CLAY PURIFIER Russian patent published in 1996 - IPC

FIELD: manufacture of building materials. SUBSTANCE: clay purifier has housing and filtering lattice in the form of cylinder with lateral surface formed from plates located with space. The terminal part of drive auger is placed in cylinder cavity. The front surface of auger terminal part is inclined at acute angle to cylinder generatrix towards collector. The value of acute angle does not exceed the double angle of friction of the pair formed by reprocessed material and material of working areas of auger and cylinder and exceeds the double angle of friction of the pair formed by stone-like impurities and material of working surfaces of auger and cylinder. Rotor in the shape of toothed disks fastened with spaces on drive horizontal shaft is mounted in collector of stone-like impurities. The cover is made with vertical slots for placing disk teeth. Purifying knives are disposed in the spaces between toothed disks of rotor. EFFECT: enhanced efficiency of enriching ceramic masses. 3 cl, 3 dwg
