Factors affecting grinding throughput - Minerallurgy

Factors on throughput. The throughput in grinding mills (tonnes/hour) is dependent on the mechanical properties of the mill feed, the mill dimensions and how the mill is operated i.e. rotational speed, water content, fill level etc. In general the throughput in the mills is lower the higher the strength of the feed material is, and the strength ...
