ABSTRACT:
In a comminuter for solid material, which includes a plurality of upright abrasive rolls mounted in a circle to form a comminuting chamber, an improvement in the comminuting roll includes the provision of a plurality of radially directed apertures formed in the surface of the rolls to pick up product from the interior of the comminuting chamber and deposit it adjacent the outer perimeter of the comminuter as the rolls rotate. The aperture may, but need not, extend through the roll. In operation, the particles of comminuted material enter the apertures in the surface of the roll. The roll is then rotated at a speed that is sufficient to provide a centrifugal force on the particular that dislodges them from the apertures when the aperture is positioned outwardly of the comminuting chamber. The particles that are picked up from the comminuting chamber are thus deposited outside the comminuting chamber.
