In general lines the grinding circuit is composed by a powdering or pulverizing process and a classification process. In most sites a ball mill is used for grinding to produce fine particles and a (hydro) cyclone is used for classification to seperate the fine particles from larger particles.
This ball mill also called mill for measuring bond work index is a key device for measuring grinding work index. It is widely used by teaching and researching departments for grindability test of cement materials and mixtures.
qm3 ball mill for measuring grinding work index. qm 3 ball mill for measuring grinding work index . A bond ball mill work index is then performed on the mill product for the design of sagball mill circuits this is important because it was found that there was a kwht higher ball mill work index if the mm ball mill test feed size is obtained by sag mill grinding
