CENTRIFUGAL REFLECTOR-TYPE MILL Russian patent published in 1995 - IPC

FIELD: crushing mechanisms. SUBSTANCE: material to be crushed is fed onto rotor 5 with radial channels. For initial crushing, lumps of materials are thrown by centrifugal force against reflecting plates 11 fastened on the inner surface of housing 1. Large particles are taken away from discharge pipe 9; fine particles are taken by the flow of energy carrier entering the chamber of housing via nozzle 12. Crushed to the size desired, particles are sent via pipe 14 to cyclone 15 to be gathered in hopper 16 for subsequent removal through discharging device 17. After cleaning, the energy carrier is thrown away to the atmosphere by fan 11. EFFECT: higher efficiency and reliability. 1 dwg
