微粉砕装置
Document Type and Number:
Japanese Patent JP5160453
Kind Code:
B2
Abstract:
A pulverizer simplified in structure for easy maintenance and suppressed in cost. The pulverizer has a hopper (2) provided on one side thereof, a product discharge hole (4) provided on the other side thereof, and a raw material crushing chamber (3) for crushing raw material that is fed from the hopper (2) and discharging the crushed material from the product discharge hole (4) . The pulverizer further has at least one thin plate-like rotor (8) disposed on the upstream side inside the raw material crushing chamber (3), a hollow circular cylindrical space (S1) in which the rotor is placed, a classifying space (C) disposed on the downstream side of the hollow circular cylindrical space (S1) and formed in a hollow circular cylindrical shape having an inner diameter smaller than the hollow cylindrical space (S1), and a product discharge hole (4) which is coaxially disposed on the downstream side of the classifying space (C) having an inner diameter smaller than the classifying space (C). Airflow produced by the rotation of the rotor (8) causes raw materials to collide with each other to crush them or causes raw materials to collide with the inner wall surface of the raw material crushing chamber to crush them.
