Abstract:
1. A cyclone for classifying materials comprising: a) a head section; b) an inlet duct connected to said head section for directing the materials to be classified into said head section at high velocity; c) a cover plate mounted on said head section and having a nozzle which forms an overflow outlet; d) a conical housing of downwardly tapering configuration depending from the bottom end of said head section to receive the materials to be classified from said head section for classifying the received materials into relatively smaller and larger particles, said conical housing having open sides and including, e) at least one vibrating device mounted on said conical housing for generating vibrations therein for increasing the amount of smaller particles classified in said conical housing; f) means on said conical housing for mounting said vibrating device on one of said strut means of said conical housing; and g) a downwardly tapering apex cone extending from the bottom end of said conical housing for creating a vortex to carry the smaller particles of the materials classified in said conical housing upwardly through said conical housing and said head section and through the overflow outlet provided by said nozzle.
