ABSTRACT:
An apparatus 10 for precise treatment of powder/particle of the invention includes a vessel 11 which can be sealingly closed by a closure carrying a raw material supply on its upper surface, a rotary shaft 12 extending through the center of the bottom surface of the vessel, an agitation blade assembly 13 extending from the upper end of the rotary shaft in a radial array along the bottom surface of the vessel 11, and a chopper 36 for adjusting grain diameters of powder/particles mixed by the assembly. A horizontal turntable 24 is fixedly mounted on the upper end of the rotary shaft 12. A second rotary shaft 25 extends along the axis of the rotary shaft 12 and through the turntable 24. A second agitation blade assembly 27 extends in a radial array along the front surface of the turntable 24. The rotational speed of the second agitation blade assembly 27 and a mixer blade assembly 34 is higher than the rotational speed of the turntable 24.
