FRAGILE MATERIAL GRINDING METHOD Russian patent published in 2000 - IPC

FIELD: mechanical engineering. SUBSTANCE: method involves feeding fragile material into working cavity; exposing fragile material to the action of milling bodies; discharging ground material. Grinding process is performed by direct action of cleaving, cutting, crushing and rubbing forces created between movable and immovable surfaces. Working cavity defined between movable and immovable surfaces is reducing in the direction of advancement of fragile material up to predetermined size of particles. Ground material is discharged in radial direction through at least one discharge slit. Size of particles is regulated and determined from formula presented in Specifications. Method allows continuous intensified grinding process to be performed for single stage till obtaining particles with size not exceeding predetermined value. EFFECT: increased efficiency and simplified method. 1 dwg
