Based on this selection criteria it would be common practice to offer, twelve smaller 400 mm diameter hydrocyclones to meet the performance requirements. Through the reduction in pressure and the use of specific sets of cyclone fittings, the smaller hydrocyclone will cut coarser allowing it to meet the classification target in the overflow.

Selection of the hydrocyclone is an essential part of grinding circuit design. Improper hydrocyclone selection leads to poor grinding circuit operation. For example, large diameter hydrocyclones have been installed in low throughput regrind circuits with only two hydrocyclones in operation during full plant production.

The hydrocyclone is a simple piece of equipment that uses fluid pressure to generate centrifugal force and a flow pattern which can separate particles or droplets from a liquid medium. These particles or droplets must have a sufficiently different density relative to the medium in order to achieve separation. The flow pattern in a hydrocyclone ...

Hydrocyclones demonstrate a trait that is useful for gold mills—minerals with higher specific gravities have a progressively finer cut-size (whether this is desired or not). In plants with free-milling gold, this leads to gold concentrating in the milling circuits (see Figure 17.13).On a size-by-size basis, concentrations of up to 100 times can occur in …
