Abnormal wear patterns in liners normally suggest abnormal mill operating conditions. The operation of a mill with too dilute a slurry charge for example can result in severe slip between the charge and the lining and lead to accelerated wear. An example of this phenomenon is shown for a wave type liner design in a 6MW ball mill in Figure 35.
effect of liner type and wear on ball mill grinding efficiency and throughput. This thesis provides a comprehensive analysis of key mill operating parameters and addresses the following key research question: how does liner type, lifter face angle, and …

Ball Mill Composite liners are a new type of liners, particularly engineered by TOMINE to address SAG mill leakage due to discontinuous cracks in large alloy liners or loose liner bolts with insufficient pre-tightening force, and over-grinding of material. This type of liners extends the service life of liners and improves the mill grinding ...
The type of ball mill liner known as a grate liner is designed for discharge efficiency. It allows the discharge of ground materials via slots. With the Magotteaux range of alloys and their experience a longer lifetime and optimal grinding can be achieved. Designs of grate liners depend on their drilling pattern, mill speed, grinding media ...
Grate Discharge Ball Mills: In this type of mill, the ground materials are discharged through the grate plate, which prevents the grinding media from exiting the mill. ... Mill Liners: Liners protect the mill shell from wear and facilitate the movement of grinding media. They are typically made of rubber, metal, or composite materials.
High Chrome/Moly Iron Liners > 600 – 700 BHN Cr iron- rod mills and ball mills > Excellent abrasion resistance. Provide the best combination of toughness and abrasion resistance among white cast irons.
