BULK FEED GRINDING APPARATUS Russian patent published in 2006 - IPC B02C13/04 

FIELD: mechanical engineering, in particular, mechanized preparing of bulk feeds.

SUBSTANCE: apparatus has cylindrical casing with charging hopper, pneumatic pipeline, fan communicated through tangential branch pipe to cyclone, wherein tilt board is established, and branch pipe for discharging of ready products. Flare with discharge channels is mounted on casing. Cyclone is communicating via return air pipeline and corrugated branch pipe with working chamber of apparatus for feeding of large fodder lumps to said chamber. Window for feeding of large particles is positioned on vertical shaft of casing at a distance making 2/3 the radius and half the distance between windows of channels of said branch pipe. Casing incorporates rotor with hammers and cylindrical toothed deck consisting of two parts. Lower part of deck is rigidly fixed, and upper part is shortened by an angle of 30-45 deg and positioned for axial rotation.

EFFECT: provision for uniform milling, simplified construction and reduced specific consumption of power for milling process.
