DEVICE FOR SEPARATION OF LOOSE MATERIALS Russian patent published in 1995 - IPC

FIELD: concentration of materials; applicable in construction, chemical, mining and other industries. SUBSTANCE: device for separation of loose materials has body whose upper part accommodates loading inlet, thrower and baffle, fixed deflecting plates installed under thrower. One plate is connected with body wall opposite to wall with baffle, and the other plate is located between deflecting plate connected with body wall and baffle and has deflecting surfaces. Installed in body lower part are discharge outlets with shut-off and regulating members, air intake inlet, branch pipes of aspiration system, separating grate, redistribution chamber with discharge outlets and shut-off and regulating members located under separating grate and adjacent side. Installed under outlets are sieves of fine separation of fine and coarse fractions of material with inclination towards inclination of separating grate. Bypass collector is brought to lower edge of deflecting plate connected with body wall and in form of trough having form of angle with top located along axis of trough symmetry. Bypass collector is directed with its one end towards deflecting plate with deflecting surfaces and with its other end communicating with under-sieve space. Air intake inlets and bypass collector are provided with shut-off and regulating members. EFFECT: higher efficiency. 2 cl, 3 dwg
