Abstract

A pulverizing apparatus comprising: a grinding chamber formed between the inlet of materials and the outlet of the materials with bearings at the bottom, a shaft supported in the bearings extending into the grinding chamber and being driven by a motor, a conical plate mounted on the shaft with more than one radial blades or radial hammer plates on its inner surface, a powder selector, an air-blower and an air duct connecting the blower with the grinding chamber, the air vent of said air duct located above the conical plate. The pulverizing apparatus merges hammer pulverization, impact pulverization and power self-grind into a whole, which simultaneously finishes intermediate crush, fine crush and grinding materials, and which can improve the fineness and transmit the unfinished product into a selecting system by creating the high speed vortex.
