摘要

FIELD: concentration of mineral resources. SUBSTANCE: the device is furnished with a diverging recleaner cell connected to a branch pipe used for unloading of sands and having arrangements for trapping the heavy fraction tightly secured in its bottom; the arrangements are made in the form of vertically installed cylinders with conical bottoms, having outlets in the vertexes of the cones, and tangential branch pipes installed on the cylinder walls, in the joint with the conical bottoms; the diverging recleaner cell on the side of the wider end is furnished with an adjustable overflow threshold and a chute for reception of pulp with fine-grained fraction; the cylinders of the arrangements have an annular shoulder secured on the cylinder internal surface at the level of its upper end. EFFECT: improved design.
