RME BOLTBOSS is an integrated technology toolset that allows SAG, AG and ball mill liner bolts to be secured from outside the mill during new liner placement. The system enables safer liner installation by eliminating the need for reline crew to be on the mill charge and in the vicinity of mill relining machine (MRM) movements during liner placement.


  • Transforms risk and safety: holds, installs and secures liner bolts from outside the mill.
  • Improves process efficiency: liner bolts are fixed in place before entering the mill.
  • Reduces confined space, at-height and mobile plant operational hazards for reline crews.
  • Universal system suitable for SAG, AG and ball mills.
  • Works with a range of liner designs including feed, shell and pulp lifters from leading OEMs.
  • Avoids liner installation challenges associated with other liner bolting solutions.
  • Requires less crew for placement to improve resource allocation to value-adding activities.
  • Enables MRM operators to increase liner manipulation speed without risk to crew safety.
  • Reduces the duration of the liner placement phase.
  • Creates new opportunities to improve mill availability.

  • Versatile two (2) bolt holding system – magnetic collars and wave clips – for a variety of liner bolt lengths and angles associated with their location inside the mill
  • Secure bolt retention system holds liner bolts up to 7kg
  • Bolt slide hammer for pulling retained bolts through the mill shell from outside the mill
  • Camera system to assist external crew align, secure and install liner bolts
