Hydrocyclone - Wikipedia

A 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 two major parameters:.
