MILLING SET FOR DISK MILL Russian patent published in 2006 - IPC B02C7/12 

FIELD: equipment for milling of materials.

SUBSTANCE: milling set for disk mill has disks assembled from sections, namely, stator disk and rotor disk. Working surface of said disks has peripheral annular zone with working knives extending in equally spaced relation from inlet to outlet edges of sections on its end portions, with annular separating channels being provided between said portions, and central annular zone with integral and small-sized knives. Central annular zone is made conical, with generatrix of said zone being inclined in its mid portion of conicity at an angle of 6-11 deg and in entrance part of conicity joined with inlet peripheral edge of peripheral annular zone at an angle of 12-17 deg relative to supporting surface of sections. Integral knives of central annular zone are arranged in alternation with two small-sized knives, between which knives one shortened knife is positioned. Channels arranged between knives are open in direction from inlet annular edge, and knives of subsequent annular portion of peripheral annular zone relative to previous annular portion are arranged in staggered order.

EFFECT: intensified milling process, improved quality of milling, and reduced consumption of power.
