Mill Relining

More than liner replacements

SPS also offer expertise in the following areas:

  • Mill backing rubber replacement: Backing rubber is essential to protect the mill shell. SPS is an industry leader in mill backing rubber replacement during relines, by effectively coordinating rubber work activities during relines to deliver a complete reline service.
  • Bolt torquing: Correctly torqued mill bolts are an important part of the relining process. Executing this function correctly reduces the possibility of bolts getting loose and breaking during normal operation. At SPS we have a large range of calibrated torque units for every bolt fastening application, using Norbar, Torcup, and RAD Torque systems ranging from 500Nm to 8000Nm.
  • Trommel and Trunnion liners: Worn mill trunnions can result in bearing failures and cause structural failure of the entire mill. At SPS we have the resources and knowledge to minimize change out time for trunnion liners and trommel screens. Repair and manufacturing options are available.
  • Liner life-cycle solutions: SPS can offer liner scanning solutions and optimised specific liner design, through our partnership with Outotec.
