Sizing of cylpebs or ball media depends on the end product fineness and also the feed size. Selection of the mill lining; for soft minerals usually steel linings are used, sometimes with a high chromium content option, which reduces material discoloration.
Therefore it is important to maintain the size of products there are many factors that influence the size of product, some of these factors are; Feed rate – With a high feed rate, less size reduction is effected since in this case the material is present in the mill for a shorter time.
Enter the width of a mill shell liner. Note this is not the width of a lifter! You may use the Mill Liner Effective Width calculation to determine this value. The mill critical speed will be calculated based on the diameter (above) less twice this shell liner width. Mill Actual

In Grinding, selecting (calculate) the correct or optimum ball size that allows for the best and optimum/ideal or target grind size to be achieved by your ball mill is an important thing for a Mineral Processing Engineer AKA Metallurgist to do. Often, the ball used in ball mills is oversize "just in case". Well, this safety factor can cost you much in recovery and/or mill liner wear and ...
It uses to help determine the grinding media optimal size must be loaded into the ball mill for proper operation ensure. The calculation formula is below: B — the grinding balls diameter, mm; A — the correction factor (for grinding balls A = 20,17; for cilpence A = 18,15);
A ball mill is a type of grinder used to grind or blend materials for use in mineral dressing processes, paints, pyrotechnics, ceramics, and selective laser sintering. It works on the principle of impact and attrition: size reduction is done by impact as the balls drop from near the top of the shell. A ball mill consists of a hollow ...
