摘要：
A method and apparatus for the classification of solid particles, in particular powdery catalytic components for the polymerization of olefins, which comprises sending solid particles suspended in a transporting gas flow through a screening device. Immediately upstream to the screening device there is an auxiliary fluidized bed classifier, in which the top of the bed is at the level of the lower part of the screening device.
