Hydraulic classification | CTP

Hydraulic classification consists of separating solid particles suspended in a liquid (pulp) into two distinct particle size fractions – fine (or overflow) and coarse (or underflow). The principle of separation is based on the effective size of the particles by difference in sedimentation velocity in a liquid. This type of classification is made for particle sizes of between 15 and 800 µm.
