Minerals processing plants typically use grinding mills in closed circuit with hydrocyclone batteries to produce slurry with a very specific particle size distribution. This size distribution is critical to the performance of the recovery stage of flotation. Therefore it is important to operate the hydrocyclone battery within its design set points. Tangential velocity and slurry feed density are critical to the operation of the hydrocyclone battery. Tangential velocity is inferred from either battery pressure or volumetric flow in the feed line while density is measured directly using a density meter. That is why most closed circuit grinding operations employ a volumetric flow meter and a density meter on the hydrocyclone feed line.
