Russell Mineral Equipment is asked many questions about our company, our operations, and our equipment and services. The list here aims to answer some of the commonly asked queries we receive. If you have any queries that are not answered in this list below, please try using the search facility at the top right hand side of this page. Of course, you are welcome to contact us for more information.

Can we ask for your help when we are designing our mill floor?


Experience has shown that the maintenance of the grinding mills is often not considered in the overall concentrator plant design. Simple factors, if considered during the design phase, have minimal effect on the overall plant capital cost but the effect on operating costs and plant availability can be large. This is especially true as the mills increase in size and the relining process becomes a complex combination of material flow, labour organisation and effective use of automation. The difference between a plant with allowances made during design for relining of the grinding mills and one that has no allowances can have an overall effect on annual availability of 2% or more.

RME has a wealth of information available and experienced people to talk to regarding the key things that need to be taken into account.

To discuss a project in design or arrange a visit from one of our experienced people to present and discuss design for mill relining, please contact us.

Are your systems quality assured e.g ISO?

Russell Mineral Equipment is certified a Quality, Environmental and OH&S Management Company (Certificates QEC27341, CEM21718, OHS21236) under the internationally recognised ISO 9001:2015, ISO 14001:2015, AS/NZS 4801:2001 and OHSAS 18001:2007 quality standards for the provision of the design, production, customer support and service of specialist mining and mineral processing equipment..

Can I use your equipment in a cement mill?


A number of the components of the RME Mill Relining Systems suite of technologies have found application in cement mills.

For more information contact RME.

Can RME equipment be installed onto a mill floor if we have already used another machine and it needs to be replaced?


It is extremely rare that RME has not been able to provide a Mill Relining System product or whole solution that improves reline speed, reliability or safety at a site. This is as relevant to sites that are replacing or upgrading older machines as it is to any site looking for a Mill Relining Machine or Mill Liner Handler or any one of the various Mill Relining System products for the first time.

Details such as tie downs, mill access and other site conditions need to be considered in designing the new machine, and decisions regarding whether to utilise the existing infrastructure or to make modifications will be discussed with the project manager at an early stage.

For more information, contact us.


Can your equipment interface with any steel liner, even the ones made in my country?

With the range of O-ZONE Liner Lifting Tools, RME's Mill Liner Handler can interface with all but very few liners manufactured worldwide. Steel liners fitted with lugs pose no problem, and if the liner is made from alternative materials then it can usually be lifted by the Mill Liner Handler using slings or custom designed brackets.

RME's Mill Relining Machine has a grapple mechanism, with a pinning configuration that can function within a defined range of width between the liner lugs and lug hole diameters. RME can supply details of the desired lug spacing to enable our clients to liaise with their liner supplier regarding lug configuration requirements. The grapple is also fitted with a rigging hook to enable the RME O-ZONE Hooks to be used on liners with no lugs.

So for any mill with liners with or without lugs and any combination thereof, a RUSSELL Mill Liner Handler or a RUSSELL Mill Relining Machine can be used successfully. RME recommends an assessment of the value of the mill and the cost of the downtime should be undertaken to determine the best economic decision for a particular mill and liner combination. RME is constantly in contact with all the grinding mill suppliers and grinding mill liner suppliers globally and is happy to discuss liner design details for optimum reline efficiency with you or your supplier to enable you to achieve maximum throughput and mill availability.

For more information, contact us.


Do you offer solutions for Vertical Mills?

Industry has started to install greater numbers of large vertical grinding mills. RME has manufactured and installed the first system and is pleased to be able to offer a liner handling solution for vertical mills with liner weights up to 10 tonnes.

For more information regarding RME's Vertical Mill Liner Handler solution, follow this link, or for a quote please click here.

Do you offer solutions for HPGRs?

With some of the larger individual rollers used in High Pressure Grinding Roller installations weighing in at over 100 tonnes, RME has designed and manufactured a solution for transporting the rolls when the time comes for swapping rollers over for refurbishment in space constrained plants. For more information regarding Russell Mineral Equipment's HPGR handling solutions, click here, or to contact us for more information, follow this link.

How do I measure Mill Reline Performance?

The simplest method of measuring Mill Reline Performance is to record the total time (in hours) the mill is stopped and record the total number of liners removed and installed and then divide the second number by the first number to give a pieces per hour figure. While this is not a very detailed analysis, it does provide a basis for measuring improvement over the long term.

To analyse the effect of specific improvements or, to identify specific causes of lost time, most companies operating world class reline operations dedicate specific people to recording individual events around the clock during a reline. RME is constantly researching methods for the improvement in Mill Relining Time and can help you with analysis of your data and suggest areas for improvement. Please contact RME for further details.

Is a Mill Relining Machine different to a Mill Liner Handler?

A Mill Relining Machine differs from a Mill Liner Handler in a number of ways:

  • A Mill Relining Machine is fitted with a grapple mechanism which securely holds new liners, and enables them to be precisely mechanically manipulated into the exact location without manual intervention. A Mill Liner Handler uses a hook and sling (see also O-ZONE Tools) to carry the new liner from the liner cart or from the mill floor to the general location where the liner is to be fitted and manual intervention is required to position the liner ready for bolting.
  • A Mill Relining Machine can place liners above the centreline of the mill whereas a Mill Liner Handler can usually only be used to sling liners into position below the centreline of the mill due to the need for manual intervention to mate the liner with the mill shell.
  • A Mill Relining Machine can perform all the same operations as a Mill Liner Handler but the reverse is not true.
  • A Mill Liner Handler has only three axes of movement whereas a Mill Relining Machine normally has seven or more. The grapple accounts for the additional 4 or 5 axes difference between a Mill Liner Handler and a Mill Relining Machine.
  • A Mill Relining Machine is generally designed to manipulate liners of larger size and mass, whereas Mill Liner Handlers are typically designed to lift smaller, lighter liners (up to 1500kg). The reason for the 1500kg limit for Mill Liner Handlers is that manually manipulating liners heavier than 1000kg into place can become unsafe and slow.

How long will your equipment last for?

Depending on frequency of use and how well a machine has been maintained RME equipment is designed to have a very long life span. By way of example, RME's second and third oldest machines are still in operation at site over 20 years since commencing service. The first machine is now located in pride of place in our head office having been replaced by another RME Mill Relining Machine at site.

RME offers an onsite maintenance service for all of its installed fleet of Mill Relining Machines, Mill Liner Handlers and THUNDERBOLT Hammers. RME also maintains a full complement of spares and upgrade solutions to maintain all RME equipment in top condition, regardless of age. A number of RME's customers have engaged RME in 3-5 year service contracts, to reduce the demands on onsite maintenance personnel and ensure that the longer term reliability of the equipment is maintained.

The fleet of installed Mill Relining Machines and Mill Liner Handlers is aging but still very much operational, and because technology is progressing, RME also offers customers a service to refurbish and update older machines to ensure that they remain current and that their life extends to the life of the mine.

For more information contact us, or to request a quote regarding service or major rebuilds, click here.


How many THUNDERBOLT Hammers do I need for my mill?

This answer requires a review of the specific mill and mill surrounds, taking into account limitations and opportunities that present themselves.

For a site with no limitations, the perfect answer may be twelve or more THUNDERBOLT Hammers with mobile suspension supporting relining on both sides of the mill at the same time. For another site the solution may be two THUNDERBOLT Hammers suspended via fixed monorails, and a third suspended via a high post jib. The 'perfect' solution will almost always be moderated by factors such as site layout including other equipment installed near the grinding mill, space around the mill and mill size and configuration.

For this reason, Russell Mineral Equipment personnel are happy to assist with specification of the THUNDERBOLT Hammer and Suspension options that will provide the most effective liner bolt removal solution for each site.

For more information, contact us.


Is your equipment CE Certified?

RME has supplied several CE Certified systems and individual products into countries requiring CE Certification. We are pleased to advise that we are able to supply CE Certified products for mine sites that require it.

To discuss the details, please contact us.


What are O-ZONE Liner Lifting Tools?

After an extensive Research and Development effort the O-ZONE Liner Lifting Tools range was added to the Mill Relining System suite of technologies in 2007. The idea was borne out of the problem of how to safely and quickly secure worn and new liners so that they can be moved with the Mill Relining Machine or Mill Liner Handler. Prior to the invention of the O-ZONE Liner Lifting Tools, crowbars and slings made of a variety of materials were used, and many reline operators suffered crush injuries as a result.

The range of O-ZONE Liner Lifting Tools currently comprises:

Each of these elements has been designed to be used in conjunction with the other components of the O-ZONE range, and is also offered in a range of capacities to accommodate the lifting requirements at each site.

O-ZONE Liner Lifting Tools are designed and tested to meet both Australian Standard and CE lifting equipment requirements. For example within each batch produced, one set is proof tested to 4 times the Working Load Limit (WLL) and discarded, and every tool is load tested to 2 times its WLL, to ensure that their lifting capacity rating can be assured.

The O-ZONE Liner Lifting Tools have been proven to dramatically reduce reline time. In a typical example five hours was saved on the reline time of a large Ball Mill in where O-ZONE Liner Lifting Tools saved over 1 minute per liner for 300 liners.


What is a Mill Liner Handler?

Mill liners are designed to be sacrificial linings to protect grinding mill shells and to enhance the movement of the charge for optimum throughput and grinding performance. A Mill Liner Handler is a purpose designed machine used to remove and insert liners in grinding mills. Typically, RME's Mill Liner Handlers find application in AG, SAG, Ball and Rod mills throughout the hard rock mining regions of the world. Mill Liner Handlers as they are today were invented by John Russell of Russell Mineral Equipment to make the process of replacing mill liners faster, safer and more reliable.

Prior to the introduction of the modern Mill Liner Handler, mill reline personnel resorted to a variety of dangerous and largely ineffectual methods for removing and inserting liners, including truck mounted cranes, overhead cranes, chains and pulleys, and brute strength. For these reasons, grinding mill relining was often a labour intensive, time consuming, and dangerous task. The range of RME's Mill Liner Handlers today provides solutions for small mills (into which a man can enter) right through to larger mills with liners up to 1500kg. For liners larger than 1500kg, Mill Relining Machines are required. Click here for an explanation of the differences between the two machine types and here for a description of a Mill Relining Machine.


What is a Mill Relining Machine?

Mill liners are designed to be sacrificial linings to protect grinding mill shells and to enhance the movement of the charge for optimum throughput and grinding performance. A Mill Relining Machine is a purpose designed machine used to remove and place liners in grinding mills. Typically, RME's Mill Relining Machines find application in the larger AG, SAG, Ball and Rod mills throughout the hard rock mining regions of the world. Mill Relining Machines as they are today were invented by John Russell of Russell Mineral Equipment to make the process of replacing mill liners faster, safer and more reliable.

Prior to the introduction of the modern Mill Relining Machine, mill reline personnel resorted to a variety of dangerous and largely inefficient methods for removing and inserting liners, including truck mounted cranes, overhead cranes, chains and pulleys, and brute strength. For these reasons grinding mills were much smaller because mill shell liners and consequently mill size was limited by the weights and sizes of the liners that could be physically manoeuvred. Furthermore the grinding process was less efficient due to the fact that liner profiles were designed for liner life (not productivity) due to the long time that it took to complete each liner change.
Today, liners up to 7250kg are able to be manoeuvred precisely into place with the 7 Axis or 8 Axis movement of a RUSSELL Mill Relining Machine. RME has Mill Relining Machines installed at sites which operate what are currently the world's largest grinding mills (40' diameter mills). Without RME's constant Mill Relining Systems innovation such massive mills would not be possible because there would be no effective way to replace the liners in them.

RME is currently working closely with key partners in the grinding mill industry to develop mill relining solutions for the next generation of AG/SAG mills, which are expected to have diameters up to 44' and liner weights up to 10 tonnes.


What is a T-MAG?

T-MAGs are the latest innovation in THUNDERBOLT Hammer moil guidance and liner bolt removal safety and efficiency. Tests have shown that effective use of T-MAGs can reduce liner bolt removal time by over 30%.

The T-MAG uses a powerful magnet attached temporarily to the mill shell to hold a high strength moil guide tube in place over the liner bolt, thereby eliminating the need for reline personnel in the THUNDERBOLT Hammer strike zone.

Prior to the introduction of the T-MAG, labourers were required to position themselves in front of the THUNDERBOLT Hammer, physically holding a cylindrical sleeve to guide the contact between the THUNDERBOLT Hammer and the liner bolt. This was a dangerous practice, as injuries caused by flying metal shards, operating in a confined space and unexpected manoeuvres by the THUNDERBOLT Hammer operator all combined to create potentially lethal operating conditions.

RME recommends having a set of at least four T-MAGs per THUNDERBOLT Hammer on site to achieve maximum liner bolt knockout efficiency. To ensure optimum safety and efficiency, T-MAGs are sized to suit specific liner bolt and washer combinations.

To request a quote for a set of T-MAGs, please click here.


What is a THUNDERBOLT Hammer?

A THUNDERBOLT Hammer has been designed to replace manual sledge hammering. A strong man, rested and with a good aim can produce a blow with a sledgehammer of around 150 Joules, and can do so for only a relatively short time due to the strenuous nature of the work. Russell Mineral Equipment invented the range of THUNDERBOLT Hammers to make the removal of liner bolts from mill shells quicker and safer. The range of THUNDERBOLT Hammers currently comprises:

  • THUNDERBOLT 1500 Recoilless Hydraulic Hammer (delivering 1500 Joule blows, at a rate of 60 blows per minute)
  • THUNDERBOLT 750 Recoilless Hydraulic Hammer (delivering 750 Joule blows, at a rate of 90 blows per minute)
  • THUNDERBOLT 450 Recoilless Pneumatic Hammer (delivering 450 Joule blows, at a rate of 60 blows per minute).

For more information regarding the range of THUNDERBOLT Hammers, please click here.



MILLMAST is the name given to Russell Mineral Equipments liner handling solution for small mills with small limited openings or limited clear space in front of the mill.

For a MILLMAST to be a suitable option, liners must typically be no heavier than 400kg, and a man must be able to enter the mill to assemble and operate the MILLMAST in the mill.

For more information click here, or to obtain a quote for a MILLMAST, follow this link.

What is the largest capacity machine I can have?

At the moment, the largest capacity that an RME Mill Relining Machine has is 8000kg. The largest RUSSELL Twin 8 Mill Relining System currently in operation is a 2 x 600kg capacity system, giving a total lifting capability of 12000kg.

With the next generation of SAG/AG Mills being designed, RME is currently considering design parameters for Mill Relining Machines that have the capacity to lift 10 tonnes.

For more information contact RME, or click here.

Why are solid rubber tyre options better than rail wheels?

RME can provide our Feed Chute Transporter, Mill Relining Machine, and Mill Liner Handler technologies mounted on rail configurations.

However, industry is tending to move away from rail mounted equipment for a combination of the following reasons:

  • Rail tracks often get filled with rock and debris, and must be regularly cleaned to allow movement of the Feed Chute Transporter or Mill Relining Machine along the track
  • Rail tracks often impede the most satisfactory location of tie downs for the Mill Relining Machine or Mill Liner Handler
  • Rubber tyre machines offer greater flexibility with regards to moving and locating the Feed Chute Transporter or Mill Relining Machine, by not confining movement to a track set into the floor
  • The all wheel steer feature which is only available on rubber tyre equipment offers maximum manoeuvrability.
  • Floor loads can be better distributed thereby allowing for decreased cost in floor construction, with weight being borne by up to 10 solid rubber tyre wheels on Feed Chute Transporters required to potentially transport loads up to 100 tonnes
  • Multiple wheel Feed Chute Transporters do not exhibit significantly higher point load events if one wheel is impeded (by a rock, for example) as the load is evenly spread across a number of independently supported wheels
  • Rubber tyre Feed Chute Transporter and Mill Relining Machine options can traverse inclines and negotiate other small obstacles located on the mill floor
  • Sophisticated manufacturing techniques and materials now produce wheels with solid rubber tyre permanently adhered to the rim resulting in long life and maintenance free operation

For more information regarding rubber tyre application in the Mill Relining Systems suite of technologies, please contact RME.


Why do I need so much room at the feed end of the mill?

The feed end of the mill is usually the 'business end' of mill relining activities. This end of the mill is typically used to access the mill to facilitate the liner exchange.

For maximum reline efficiency, it is preferable that a concentrator plant be designed to facilitate all relining functions that occur at the feed end, including:

  • manoeuvring of the Mill Relining Machine or Mill Liner Handler into and out of the feed end of the mill
  • temporary storage of new and worn liners, bolts, washers and nuts nearby to provide quick access
  • access for Feed Chute Transporters and space for storage and maintenance of the feed chute
  • room for the efficient movement of a forklift to deliver new liners and remove old liners to the liner cart
  • space for THUNDERBOLT Hammers to operate at the feed end more easily
  • location of O-ZONE Liner Lifting Tools, T-MAGs and T-MAG adapters, spare moils, and other consumables for quick access, and
  • when a mill floor is located high above ground level, storage of THUNDERBOLT Hammers and Power Packs, the Mill Relining Machine or Mill Liner Handler, and THUNDERBOLT Suspension options between relines.

When Greenfield site concentrator plant designers consider the potential opportunity to improve annual mill availability, by designing to accommodate the RME Mill Relining Systems products, the provision of space at the feed end will pay dividends for the life of the mine asset.

RME is experienced, however, in designing a custom made Mill Relining System that still delivers value for Brownfield sites where such considerations have not been taken into account or subsequent additions to installed plant have restricted the available space.

For more information, please contact RME.


How do I get access to copies of manuals for our equipment?

When a customer purchases RME equipment, our standard procedure is to supply electronic copies of Installation and Operation manuals in the language requested by the customer. Customers can also purchase hard copies of manuals if required. However, most of our customers find that the self service client login area of RME's website provides access to up to date copies of manuals for all equipment at their particular site and alleviates the need for them to store and maintain local copies.

If you do not have the login details for your site, please contact us to be setup.


Why do you have up to 10 wheels on your Feed Chute Transporters?

The Multi-Wheeled Feed Chute Transporter is the latest addition to the range of RME Feed Chute Technologies.

High floor loads are imposed by the four wheeled rubber tyre version of the Feed Chute Transporters particularly when used for the larger feed chutes now prevalent with the larger mills in modern concentrator plants. These larger feed chutes in some cases can have a potential fully choked weight exceeding 100 tonnes.

The Multi-Wheeled Feed Chute Transporter has been developed to provide a solution to reduce the costs of design and construction of a mill floor that can accept such significant loads by reducing and evenly distributing individual wheel loads.

Why use a THUNDERBOLT Hammer when I have a jackhammer?

The range of THUNDERBOLT Hammers has been specifically developed, and is still the best choice, for knocking out worn grinding mill liner bolts.

There are a number of reasons for this:

  • The THUNDERBOLT 1500, THUNDERBOLT 750 and THUNDERBOLT 450 Hammers all have a recoilless action making them a more ergonomic , more controlled choice
  • The action of a jackhammer requires the influence of gravity and downward pressure to fully and efficiently transfer their blow energy
  • Without modification, a jackhammer is awkward to suspend horizontally and difficult to maintain sufficient horizontally force
  • The THUNDERBOLT 1500 and THUNDERBOLT 750 are supplied with their own hydraulic power pack, and the THUNDERBOLT 450 is recommended to be used with the TURBO 500 Air Intensifier, and in doing so are not dependent on site air, which can sometimes be unreliable
  • The noise generated by a THUNDERBOLT Hammer is greatly reduced relative to a jackhammer
  • The THUNDERBOLT Hammer range can be supplied with a range of suspension options, suitable to most site conditions, and to the effective operation of the Hammers
  • A THUNDERBOLT Hammer delivers a series of controlled, high intensity blows with precision. A jackhammer takes more of a 'scatter gun' approach, delivering multiple difficult to control blows of reduced energy. In most cases the use of jack hammers has resulted in damage to the mill shell around the liner bolt holes resulting in poor sealing and leaks during the mill operation.



Why do you recommend suspension options for my THUNDERBOLT Equipment when I can use the overhead crane?

Experienced mill maintenance managers will know that the one of the most heavily utilised pieces of equipment during a plant shutdown is the overhead crane. The overhead crane is also normally designed to lift and transport pieces of equipment with weights far exceeding that of a THUNDERBOLT Hammer and as such it is a slow and inefficient means of supporting THUNDERBOLT Hammers during liner bolt knock removal.

For these reasons, the overhead crane should not be used for suspending the THUNDERBOLT Hammers during a reline. To ensure maximum efficiency of liner bolt knock in, RME recommends that THUNDERBOLT Hammers be supplied with their own THUNDERBOLT Suspension option.

For more information, contact RME.

Please send me the operation and service manual for our equipment

All our equipment is supplied with installation and operation manuals. However, we know that sometimes they aren't always able to be found at site when they are needed the most. RME has enhanced our customer access to the relevant manuals for their own Mill Relining Systems products, by providing a new self-serve client access portal which enables customers to download manuals, or relevant sections, whenever they are required. All sites have been provided with a username and login, but if this too has been misplaced, RME can renew the access for current site personnel.

Can I download my installation and operation manual (IOM)?

All manuals relevant to the equipment at each site are available via you login at our client access portal. If you cannot find the required manual after logging in or do not have login details please contact us.

How do I get a quote on all of the items I need to improve the relining time of my mill?

Each Mill Relining System solution is unique and customised to accommodate each concentrator plant's characteristics. Due to the large number of constraints and design considerations RME requires a considerable amount of information to provide a firm quote and confirm machine suitability for each mill. However, we understand this information is not always readily available and as such we are also able to provide a quote based on limited information that can be used for budgetary and feasibility planning. When the time comes to place an order RME can also help with a site visit from one of our experienced engineers to gather all the required dimensions and information.

Feel free to use the Request a Quote facility on this website, or contact us to discuss your requirements.

How do I know which products I need?

Russell Mineral Equipment works closely with our existing and potential customers to assist them to identify the best possible solution for their particular situation. RME's team of Engineers and Key Account Managers work closely together with the customer or Engineering, Procurement and Construction Manager (EPCM) to identify the customised Mill Relining System that will provide the best value for money.

Having detailed information on current relining practices (such as reports on lost time or pieces per hour) greatly enhances RME's ability to advise on the best approach based on our experiences globally.

Feel free to Contact us for advice or review our products listing for more information.

Do you outsource any of your manufacturing?

For many years, Russell Mineral Equipment has designed, fabricated and assembled the majority equipment at our facilities in Toowoomba, Queensland, Australia. Our staff are highly trained and skilled in their specialised fields, and take great pride in manufacturing the highest quality product possible.

We do however recognise the capabilities of specialists in various products and services and as such we seek out the best suppliers and outsource a few highly specialised manufacturing tasks to these firms under strict quality controlled conditions. This enables RME to concentrate our highly trained and specialised workforce on the tasks and components that make RME the market leader. On average the amount of manufacturing that is sourced from external suppliers is limited to less than 15% of the total manufacturing throughput.


Do you have an agent in my area?

Due to the highly technical and customised nature of Mill Relining Systems and the relatively small market size RME does not sell products or services through distributors or agents. All products and services are sold through wholly owned subsidiaries. This way RME has complete control over the quality of parts and services offered.

RME reinvests a relatively large percentage of revenue every year in staff training and research and development to ensure our customers get the best possible advice and the right product to suit their needs. Please contact your nearest RME office for professional sales, service and support.


We're in the middle of a reline and we need your help NOW!

RME experts can be contacted on our 24 Hour Service Hotlines.

Alternatively, during regular business hours we are available at each of our locations, to assist.


Why is RME the market leader?

We have heard from our customers that Russell Mineral Equipment is their first choice in Mill Relining Systems. This is a position that we are very proud of, and do not take for granted.

RME was the first company in the world to identify that mechanising the mill relining process could take the activity off the maintenance critical path. RME has stated for many years "when the mill stops turning, the mine stops earning" and so our research and development focus for 25 years has been on developing a suite of complementary mill relining technologies, known today as the RME Mill Relining System, to further increase annual grinding mill availability.

Russell Mineral Equipment is the only company in the world to offer a Mill Relining System solution. This is one of the key reasons why our customers have been able to achieve reductions in reline time of 75%. With just a mill relining machine, a site can reduce the time to reline considerably. However, without Mill Relining Systems elements such as RME's T-MAGs, O-ZONE Tools, THUNDERBOLT Hammers and Suspension, concentrator plant operators are limited in their ability to achieve world's best mill relining time and consequently maximise plant availability.

RME's Mill Relining System is backed up by quality in design and manufacture, which means reliability for our customers. We stand by our decisions to only use highest quality inputs and components in our products, because we know how critical operational performance is when a shutdown is underway.

Quality equipment is limited in the life time value it can provide if it is not backed by quality service and spare parts. RME invests heavily in recruitment, training and development and retention of staff to ensure quality equipment is backed by market leading support long after the initial purchase is forgotten.


How do you transport your mill relining machines to site?

To mainland Australia based mine sites, RME's Mill Relining Machines are usually transported largely intact by semi trailer or low loader to their destinations.

To all destinations outside of mainland Australia, Mill Relining Machines are packed into 40' open top standard gauge shipping containers and loaded onto ships at the Brisbane port in the state of Queensland, Australia. After factory commissioning and tests are complete, the machines are partially disassembled as required to fit in the containers and distribute load evenly. The components are then carefully packed into the open top containers fitted out with purpose built supporting structures for the equipment components. Due to the size, weight and complexity of the individual machines RME strongly recommends transportation to site in the original container.

Upon arrival at site, our trained technicians will assist site personnel with unpacking and assembly and recommissioning of the Mill Relining Machine, and provide training in its operation. To unpack the Mill Relining Machine or Mill Liner Handler at site a mobile crane and basic metal cutting and grinding capabilities are required to free the machine from the packing structure.


In terms of location, are we too remote for RME's equipment and service?


RME operates effectively throughout all major hard rock mining regions in the world. We have increasing capacity to provide after sales service, support, and spares for each of these installations.

For more information regarding where Russell Mineral Equipment is currently located, click here, or contact us.


Where is the coldest region that your equipment is in operation?

RME has installations in the major hard rock mining regions throughout the world. It would be difficult to pick exactly which site is the coldest, but we operate in sub-Arctic conditions in Sweden, Canada, USA (Alaska), Mongolia and Russia. It is not unknown for RME's Mill Relining Technologies to operate in temperatures below -40 degrees Celsius in such locations. Operating temperatures should be specified by the customer to ensure that the appropriate modifications to the equipment are made.

Can your equipment be used in mills with rubber liners?

RUSSELL Mill Liner Handlers and Mill Relining Machines are both used on mills lined with rubber liners. The problem however, is that pure rubber liners usually have no lugs and hence limited ability to be 'manipulated' and must be lifted using slings and the rigging hook. An economic decision to use a Mill Relining Machine in preference to a Mill Liner Handler needs to be made when a large mill is rubber lined and also has steel discharge pulp lifters and grates that are coated in rubber.

Large AG mill operators have reported to RME that considering how difficult the large liners are to manoeuvre, the investment in a Mill Relining Machine can be well worth it.

Can you supply systems approved to CSA electrical standards?

RME has supplied several systems to Canada with CSA electrical inspection completed and approved either onsite by the customer or in our factory before shipment. We are pleased to advise that we are able to supply CSA electrical standards approved products for mine sites that require it.
