摘要: A dynamic classifier for a coal pulverizer has an improved drive mechanism (18, 20 and 26) which is mounted on top of concentric with the axis rotation (36) directly controllable. The variable-speed DC or AC electric motor (20) having hollow shaft (28). can produce rotor (60) rotational speeds between 50 200 RPM. supported from shaft. feed pipe (16) passes through (28) into pulverizer.
