DEVICE FOR REFINEMENT OF NONMETALLIC DETAILS

摘要

FIELD: technological processes.;SUBSTANCE: invention refers to devices for refinement of nonmetallic details. The device contains, at least, one gyrating shaft supplied by a mechanical drive located in receiving tank, intended for nonmetallic details subject to refinement. The shaft is supplied by set of the teeth intended for crushing and refinement of nonmetallic details, and teeth are positioned in rows in a radial direction on a peripheral part of the shaft so that they could interact with teeth in the course of their rotation, of at least, one motionless comb rigidly linked with receiving tank and splitting this receiving tank on the upper part, positioned above the comb, and the lower part which is positioned below the comb. The motionless comb contains an electro wire basis having certain electric potential, and the electro wire surface oriented in a direction of the upper part of receiving tank, is electrically isolated from the basis and having the electric potential which is distinct from electric potential of the basis that allows to determine presence of metal details as a result of closure of the electric circuit generated thus.;EFFECT: increase of reliability and durability of operation of the device for refinement of nonmetallic details.;10 cl, 6 dwg
