CENTRIFUGAL MILL Russian patent published in 1995 - IPC

FIELD: mechanical engineering. SUBSTANCE: centrifugal mill has housing 1. Two hollow cone-shaped disks 4 and rotating in contrary directions are coaxially mounted on shafts 2 and 3 in the housing. One of the disks is made with the smaller diameter of its cylindrical part. The distance from output face 6 of the cylindrical part of disk 4 of the smaller diameter to the base of the tapered surface of disk 5 of the greater diameter is determined by the value Δh. Besides shafts 2 and 3 with disks 4 and 5 can be disposed vertically. Disk 4 of the smaller diameter is located below. Channel 7 for feeding the crushed material is made inside shaft 3 of disk 5 of the greater diameter. EFFECT: enhanced efficiency of the equipment for the fine grinding of different materials, coal, for example, reduced energy consumption on the grind and enhanced grind efficiency. 1 cl, 3 dwg
