The sizing of ball mills and ball milling circuits from laboratory grinding tests is largely a question of applying empirical equations or factors based on accumulated experience. Different manufacturers use different methods, and it is difficult to check the validity of the sizing estimates when estimates from different sources are widely divergent. It is especially difficult to teach mill ...
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 optimum composition of the make-up ball sizes in ball mills is presented. • The effect of various factors was investigated via a grinding circuit simulation. • Binary mixtures of two ball sizes always perform better than other mixtures. • An equation is proposed for calculating the optimum composition of the make-up balls.
Throughput Optimisation in Milling Circuits Overview. All mineral processing plants have some form of comminution, with SAG and Ball Mills drawing the highest power.
SAG mills are the main workhorses in the majority of comminution circuits globally. They need to be fed and kept working round the clock. But challenges can arise when capacity is not optimised causing unnecessary downtime and liner wear leading to the one sound operators do not want to hear - the sound of the mills standing still.
A ball mill, a type of grinder, is a cylindrical device used in grinding (or mixing) materials like ores, chemicals, ceramic raw materials and paints.Ball mills rotate around a horizontal axis, partially filled with the material to be ground plus the grinding medium. Different materials are used as media, including ceramic balls, flint pebbles and stainless steel balls.
