FIELD: process engineering.
SUBSTANCE: invention relates to grinding of materials and can be used in chemical industry agriculture and production of agricultural materials. Mil comprises housing 1 with cover 2, top and bottom millstones 4, 3 with grooves 5 and rotary drive 9, 10, axial displacement mechanism 11, grain feed bin 12 and ground product discharge device 13. Note hear that surfaces of said millstones 3, 4 running in opposite directions have directed helical grooves 5. Note hear that ball-shape ledge 6 arranged in top millstone spherical recess 7 is made at central part of bottom millstone 3. Millstone shafts are shifted relative to each other to allow shifting the millstones in the planes and varying the clearance between surfaces of ledge 6 and recess in several radial directions.
EFFECT: finer grinding.
