FIELD: disintegrators and crushing devices.

SUBSTANCE: invention refers to the material grinding equipment. Disclosed is a ball mill with a classifying partition, comprising a drive, loading and unloading support journals, rigidly connected with support journals lined drum, comprising grinding bodies located after the loading support trunnion coarse grinding chamber and separated by an inter-chamber partition wall of the fine grinding chamber, classifying baffle with located coaxially lined drum and with an annular gap in relation to the unloading device, which separates the coarse grinding chamber from the fine grinding chamber, containing fixed, coaxially and without gaps fixed to lined drum, respectively facing the coarse grinding chamber perforated and fine grinding chamber annular solid discs, located between them, fixedly and without gaps fixed to solid disc, limited by unloading device, alternating perforated and solid blades dividing the gap between the discs, the lined drum and the unloading device on the front chambers and rear chambers interconnected with the unloading device, limited by perforated blades respectively contacting with classified material and opposite sides. Perforated and solid blades are located with gaps relative to perforated disc and lined drum, contacting with classified material side of perforated blades are limited on the side of perforated disc plates with height exceeding maximum height of located on blades of classified material, blades ribs closest to the lined drum and confining gaps with it, are inclined relative to it, in direction from perforated disc to solid, at angle of natural slope of material located in these gaps, wherein ribs of solid blades, limiting gaps with perforated disc and lined drum, are fixedly connected to corresponding ribs of alternating perforated blades, limiting gaps with perforated disc and lined drum, on sides, opposite sides, contacting with classified material.

EFFECT: device is aimed at improvement of mill productivity.
