"The T-MAG has been extensively tested in the field and at our Product Development centre. The data collected showed a reduction in mill bolt removal times by up to 5 hours on high wear relines of large mills and up to 3 hours on medium mills. The time saving increases when more Hammers are utilised for liner bolt knock-in."
