COARSE GRAINS DISC GRINDER Russian patent published in 2014 - IPC B02C9/00 

FIELD: process engineering.

SUBSTANCE: invention relates to feed processing shops of live farming and poultry farming complexes. Proposed grinder comprises bearing case with intake funnel. Said case houses two aligned discs facing each other by working surfaces. One of the latter is fixed at said bearing case while the other one is secured on vertical shaft. Through opening is made at fixed disc centre to communicate with aforesaid intake funnel. This grinder is equipped with assembly to adjust working clearance between said discs. Two pairs of discs are fitted on vertical shaft in parallel. Note here that separator tapered grate is arranged under the first pair of discs, its vertex facing grain board under which fitted in the second pair of discs. Fixed and moving discs have three belts of deformation: intake belt with triangular cross-section grooves with recesses facing the direction of moving disc revolution, feed belt with concentric-radial cross-section and modular belt corresponding to preset particle size arranged at one third of the disc peripheral part.

EFFECT: power savings, expanded range of particle sizes.
