(PDF) The Effect of Feed Solids Concentration on Hydrocyclone
Hydrocyclone Operation The hydrocyclone operates on the principle of terminal settling velocity of a particle in a centrifugal field. The feed is introduced tangentially, under pressure, to the cylindrical section and follows a circulating path with a net inward flow of fluid from the outside of the vortex finder. A centrifugal field is ...

Hydrocyclone System Design
When there is a single hydrocyclone, sampling is virtually impossible unless a valve was previously installed in the pump-hydrocyclone feed pipe. In operations with hydrocyclone batteries, if the central chamber lacks a sampling device, a good alternative is to slightly and briefly open the valve of one of the standby hydrocyclones, so that all ...
