How to resolve the most common hydrocyclone problems
In primary mill circuit base metal operations, hydrocyclones should be set up to produce underflow densities in the range of 50-55% by volume. Producing dilute cyclone underflow densities can lead to over grinding in the mill, translating to pay metal (product) recovery losses in flotation.

Grinding Mills - Metallurgist & Mineral Processing Engineer
Rod mills are used for primary grinding of materials with a top size of 20-30 mm (somewhat higher for soft materials). The production of fines is low and consequently a rod mill is the right machine when a steep particle size distribution curve is desired. A product with 80% minus 500 microns can be obtained in an economical manner.
