Abstract
An apparatus for classifying fine particles in slurry provides a sharp particle size distribution with few mixed coarse particles and high classification accuracy. The apparatus includes a rotor () including classification chambers () between blades () radially arranged at circumferentially regular intervals, and classifies particles so that a classified particle size is constant in an entire radial region from an outer periphery to an inner periphery of the classification chamber. The blade () of the rotor has a circumferential thickness t(d) increasing toward the outer periphery, and the classification chamber () has a width increasing toward the inner periphery.
