CONE SEPARATOR FOR HEAVY MINERALS Russian patent published in 2005 - IPC

FIELD: mining industry; devices for minerals dressing using a method of heavy minerals separation.

SUBSTANCE: the invention is pertinent to mining industry, in particular, to devices for minerals dressing using a method of heavy minerals separation. The heavy minerals cone separator includes a body, a drive, an airlift with a receiving box, a drainage sifter with a drain pan and a rabble. A zone of separation is partitioned from a stagnation zone by a ring-type cleaver-pusher. The cleaver-pusher is fixed on the rabble. The drain pan of the drainage sifter is supplied with a curvilinear launder. The launder is passing along the course of rotation of the rabble into the zone of separation. An internal wall of the body and the ring-type cleaver-pusher form the zone of separation. The diameter of the cleaver-pusher makes 0.2-0.4 of the diameter of the cylindrical part of the body. Depth of its immersing in suspension concerning to the level of overflow makes 0.3-0.5 m. The drainage sifter is displaced relatively to the axis of the rabble rotation and is installed under the receiving box of the outside airlift. The technical result is an increase and stabilization of a density of suspension in the zone of separation.

EFFECT: the invention ensures an increase and stabilization of a density of suspension in the zone of separation.
