on wear is another issue Stresses from Hertzian pressure in 4-high cold mill back up rolls were measured years ago, the results were never published, but of high interest

The basic parameters used in ball mill design (power calculations), rod mill or any tumbling mill sizing are; material to be ground, characteristics, Bond Work Index, bulk density, specific density, desired mill tonnage capacity DTPH, operating % solids or pulp density, feed size as F80 and maximum ‘chunk size’, product size as P80 and maximum and finally the type of circuit open/closed.

The calculation results can however differ from our calculation programme B_Rex (free download on the internet under siegling) These differences are a result of the basically different approaches: whereas B_Rex is based on empirical measurements.

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.

The ball mill is used for grinding materials such as coal,pigments,and fedspar for pottery Grinding can be carried out in either wet or dry but the former is carried out at low speeds The advantages of wet grinding are less power consumption,increased capacity,no dust formation etc.
