precited for a wave liner in a coal mill or block type lifters in copper ore grinding. In a carefully conducted study it was shown that the wear life of a 40 ft. SAG mill could be accurately modeled, and hence this study led to a unique design of a curve shaped lifter (Hart et al. 2006) with a lead angle of 28 degrees.

SAG Mill Liner Design

Semi-Autogenous Grinding (SAG) Mills. The shell liner profile possible is primarily determined by the chordal dimension. The profile must minimize packing and plate wear but give sufficient lift for proper grinding action. Liner profiles are as numerous as operations. They range from typical plate and lifters to "rail" or integral liners.

The Selection and Design of Mill Liners

function of mill liners. The second primary function of a liner is to transfer rotary motion of the mill to the grinding media and charge. After all, it is the interface between the mill and the grinding charge. Although work on the grinding action in mills was published 100 years ago (White 1905 and Davis 1919), the first

Key considerations when selecting a mill lining system | …

A mill lining system serves two purposes: to protect the mill shell from wear caused by the impact and abrasion of the mill charge, and to elevate and tumble the mill contents in the necessary manner to create a grinding action. To achieve this, the mill liner profile must be constructed from high wear resistant materials and incorporate ...

Grinding Media Wear Rate Calculation in Ball Mill

In the previous discussion the fact was established that the work done by a ball when it strikes at the end of its parabolic path is proportional to its weight and velocity; then, since the velocity may be considered as constant for all the balls in the mill, the work done by a ball is proportional to its weight. Since the amount of ore crushed varies as …
