Effects of grinding aid dosage on circuit performance and …

In this study, the effects of GA on transportation rate of the ground material inside the cement ball mill and the effects of this change on the whole grinding circuit were investigated. In this context, industrial tests were carried out with three different dosages of an amine-based commercial GA in a closed-circuit cement ball mill.

Key considerations when selecting a mill lining system

Rubber compounds have been developed to protect mill shells from wear, while new cast alloys and wear resistant plates can be bonded into rubber to withstand high impact abrasiveness. There is a greater understanding of how mill lining systems influence mill performance.

Composite PulpMax™ mill liners can lower costs and …

Thinner mill liners result in a larger volume inside the mill. This means you can have a higher charge level. Using composite liners also cuts the weight of the liners to about 50 percent of standard steel cast liners, making it possible to work with a higher ball charge level without increasing the total weight of the mill.

Mill liners

The shell lining has a major influence on grinding efficiency. It transforms the mill rotation into charge motion and both profile and spacing must be carefully selected to suit each specific mill. When designing a shell lining, considers the type of grinding, mill size and speed, maintenance schedules, safety, impact levels, efficient use of materials, and many other parameters.
