Abstract
The apparatus and its process utilization enables a higher throughput of ore bodies being comminuted, provides a closer or more accurate selection of size of particles or particulates produced, has a low noise level in its operation, and uses its rotor impeller to facilitate the charging-in of ore bodies to be processed, the breaking-up of such bodies, and the delivery of such bodies in the form of sized particles or particulates is introduced by suction peripherally into one of the compartments of a motor-drive impeller and axially into all of the compartments, ore bodies are introduced into all of the compartments and are thrown under centrifugal force from one of the compartments against an anvil. Broken-up bodies of a desired size are fluidized and moved upwardly out of the apparatus while those of a rejected size are returned to the impeller for reprocessing with additional ore bodies being newly introduced therein. The impeller operates in a circular housing that is cushioned and sound-proofed by a suitable resin or plastic backing. The speed of rotation of the motor drive controls the size and size range of the particles or particulates produced. Input of fluidizing air into the apparatus is provided by rotation of the impeller with the entry quantity being valvecontrolled.
