ABSTRACT:
An autogenous triturator mill for reducing particle size by colliding streams of particles in the center of a rotating bowl includes a bowl with radial vanes which is supported on a frame for rotation by a motor. Deflectors on the frame and located within the bowl intercept material centrifugally elevated in the bowl and direct the material inwardly in the form of a plurality of intersecting streams. Collision of particles in the intersecting streams reduces particle size. The concave sides of the bowl are provided with screens or foraminous walls to enable escape of fines of a pre-selected particle size from the bowl. The fines are fractioned off through the foraminous outlet as the particle size is reduced by repeated trituration or collision of the recirculating particles.
