Abstract
It is an object of the present invention to provide a particle crushing and sizing apparatus having a sufficiently wide particle crushing and sizing range, capable of being scaled down in size, and having high processing throughput. To achieve the object, a particle crushing and sizing apparatus has, in a casinga horizontally provided drive shafta plurality of circular platesfixedly supported with intervals at the drive shaftand statorsarranged so as to be opposed to plate facesat lower peripheral edges of the circular platesand each having inclined facesthat cause a gap between the plate facesof the circular platesto become narrower toward peripheral edges of the plate facesThe plate facesof the circular platesand the inclined facesof the statorsform gap portions A where particles are held, and particle crushing and sizing portions B are formed by the peripheral edges of the circular platesand narrowest gap portions between the peripheral edges of the circular platesand the inclined faces of the stators
