hydrocyclonesthe reading on the pressure gauge will allow for an accurate calculation of volumetric flow rates to the hydrocyclone which will make it possible to calculate the mass flow rate. lower cyclone pressure results in inefficiencies while high pressure increases the centrifugal force beyond its design specifications, which increases cyclone wear rate.

hydrocyclone overviewa hydrocyclone is a classifier that has two exits on the axis one on the bottom (underflow or reject) and one at the top (overflow or accept). the underflow is generally the denser or coarser fraction, while the overflow is the lighter or finer fraction. it has no moving parts and its operation depends on two major parameters
the characteristics of the feed stream.

how to improve cyclone separationgood cyclone separation depends upon control of pressure drop, pulp density and apex size. the pressure drop may vary but should not change rapidly, and is held at safe levels by keeping an adequate sump level. a falling sump level causes cavitation in the pump and reduction in feed rate; pressure drop in the cyclone falls and solids report increasingly to the overflow until the drop
