FIELD: mechanical engineering; grinders. ^ SUBSTANCE: proposed material grinding device contains charging and discharge cone-like funnels in spaces of each at least one grille and at least one knife fitted above are installed, electric motor housing with stator, squirrel-cage rotor of larger power electric motor chosen from the same series of electric motors, arranged in housing on bearings coaxially to stator and provided with hollow shaft through which auger is passed to increase transfer of ground parts of material. Axle of auger fixed relative to housing is connected in upper and lower parts with smaller bases of funnels installed with clearance relative to each other and connected with hollow shaft. Grilles are secured on inner surface of funnels. ^ EFFECT: simplified design, improved reliability and increased service life. ^ 4 cl, 1 dwg |
