DEVICE FOR WASHING AND SIZING

摘要

FIELD: washing and sizing of gravel-sand mixes, crushed rock, crushing waste, etc. SUBSTANCE: the device is a rotating crushing member of tapered sections 1 separated from one another and edges by ring disks 2. The surface of the tapered sections is made up of separate plates 4 located in overlap, attached to the ring disks by single-point bolted joints providing for their turning; in the zone of the lap the plates are attached to one another by bolted joints with bushings 6 adjusting the size of the slots so as to obtain granular material of the preset grain size. During device rotation the plane of the slotted opening attacks the watery mass of material moving in the opposite direction by its full section. EFFECT: enhanced efficiency of sizing. 3 dwgt
