autogenous wet ball mill effects

A comparison of wet and dry autogenous grinding | J ...

2021-11-26 · It has been earlier shown that the effect of dry ball mill grinding increases considerably, when the fines are efficiently removed from the mill. In this work autogenous grinding in small continuos scale has been undertaken to compare the effect of fine particle removal from the mill charge by efficient classification both wet and dry.
