DISK MILL Russian patent published in 2010 - IPC B02C7/10 

FIELD: process engineering.

SUBSTANCE: invention relates to fine-crushing devices used, for example in mining and metallurgy. Proposed disk mill comprises loading funnel 13 mounted on casing 1 accommodating lower disk 7 fitted in cantilever on drive shaft 6 and spring-loaded upper disk 10, doth disks being arranged off-center relative to each other. Disk 10 runs unobstructed and moves vertically, and has central bore to load stock in space between said disks that makes fine-crushing chamber. Proposed mill incorporates annular chamber 15 and tube 19. Note here that said annular chamber is rigidly fixed on lower disk 17. Note also that lower end of tube 19 is arranged in bottom part of chamber 15, closer to its outer wall 16, while tube upper end is located inside loading funnel 13.

EFFECT: higher efficiency of fine crushing and simplified design.
