Classifying liner – Xclass®

The revolutionary classifying liner

The Xclass® concept is a 2nd compartment tube mill liner including 2 base plates combined with deflectors/blades.

Key benefits:

  • Liner weight reduced by 20-35% vs. traditional 2nd chamber mill liners
  • Xclass® increases the useful mill diameter (from 40 to 76mm), the ball load up to 2.5 tons per EGL meter (Effective Grinding Length) and the absorbed power
  • One single bolt type to fasten all plates
  • Shorter maintenance intervention -> Reduced operating costs
  • Potential time and manpower savings during installation
