Sep 06, 2018· One of the most common types of grinding mill is a ball mill. This machine is typically used to grind material into powder. The ball mill uses a cylindrical container that rotates on a horizontal axis. This container is generally filled with the material to be ground, and a grinding medium, which refers to a substance that does the grinding.
The twostage ball mill grinding circuit run in a molybdenum mine is simulated and optimized based upon a mathematical grinding model using the population balance approach. The results of the batch grinding tests showed that the specific rates of breakage in wet grinding are .
A predictive model of the fully coupled flow of grinding media and viscous slurry (containing fine product) through an industrial scale overflow ball mill attached to a rotating trommel screen has been presented. This provides the ability to understand the behaviour of the solids and fluid phases in each of the part of the mill/trommel system.
A SAG Mill trommel screen lets you control the true discharge size of your SAG mill or the transfer size to the downstream Ball Mill circuit. A well sized trommel should not let rocks pass to the Ball Mill if they are to be more than say 5/8″ or 16mm In the image case below, strangely enough, is the mill shell liner and discharge grate manufacturer.
