The large balls tend to break down the coarse feed materials and the smaller balls help to form fine product by reducing void spaces between the balls. Ball mills grind material by impact and attrition. The degree of milling in a ball mill is influenced by; a. Residence time of the material in the mill chamber. b.

For a coal mill, we usually recommend a light classifying liners and for raw mills we recommend heavy classifying liners. If the raw materials are particularly coarse, a mixed solution might be best. This could be either by replacing the first few rings – e.g., the first 1.5 m of the chamber – with step lining or combining wave lining

Cement ball mills typically have two grinding chambers. The first chamber is filled with larger diameter grinding media andlined with lifting liners . The first chamber coarse-grinds the feed material and prepares it for the second chamber. The second chamber is the fine grinding chamber. It is lined with classifying-type millshell liners and ...
All the theory that goes into ball mill RPM's can really get people worked up, but if it isn't at a perfect RPM, it'll still do good work; it'll just take a bit longer is all. Anyway, those conveyor belt rollers are awesome for a ball mill. Those in the US can get them from Surplus Center. Those international just have to dig a bit and find a ...

Then in ball-wear formula (25), T = 6.9/K Log10 Da/Db; but from (29), K = Rt/Wt. Then T = 6.9Wt/Rt Log10 Da/Db T is 1 day, Wt is the original weight of the ball charge, and Rt is the ball wear for one day. Then Log10 Da/Db = Rt/6.9Wt are all known, and it is only necessary to solve for Db, the diameter of the balls to be added.
This document provides guidance on ball mill grinding processes. It covers topics such as ball mill design including length to diameter ratios, percent loading, critical speed, and internals evaluation. Methods for assessing ball charge, wear rates, and liner management are described. Empirical relationships for power draw and grinding laws are presented. …
