Magnetic Mill Liner

Proven Performance

The metal magnetic mill liner has been in use for years and has provided higher grinding efficiencies. The thickness of the metal magnetic liner with the protection layer is less than that of a conventional liner, resulting in a greater working volume. The metal magnetic mill liner also creates a wave form that is generated by the magnetic force and provides optimal attrition by lifting the material being ground. The higher attrition results in less abrasion and impact, which promotes a higher charge pressure and grinding efficiency.

Grinding ball chips and other debris discharged from a ball mill can cause extreme wear to downstream processing equipment. These ball chips and debris can circulate in the milling circuit and can cause excessive damage to pumps, cyclones and piping. Energy is unnecessarily consumed as these ball chips and debris must eventually be ground to a particle size small enough to allow for its discharge from the mill circuit through a cyclone overflow.

Instead, the metal magnetic mill liner will adsorb the ball chips and debris to its surface and prevent its discharge from the mill while the solid protection layer is formed. The smaller sized ball chips are sorted out and separated from the primary ball charge. These ball chips and other debris work as the liner and no excess energy is required.
