Shaking-table cross flow belt concentrator

Abstract

The invention discloses a shaking-table cross flow belt concentrator, which is provided with a frame, a head wheel, a tail wheel and conveyer belts, wherein the head wheel, the tail wheel and the conveyer belts are arranged on the frame; a tail wheel end is provided with an ore concentrate flushing drain pipe and an ore concentrate receiving groove; the low side of each conveyer belt is provided with a tailing groove; the high side of each conveyer belt is provided with an ore feeder and a flushing water pipe; the frame is supported on a sliding mechanism and moves in a reciprocating way; thehead wheel end, the tail wheel end or the lower part of the frame is provided with a push-pull rod connected with a machine head; the machine head is a mechanism with reciprocating push-pull effort; each conveyer belt is provided with a reciprocating bar; the frame is provided with a lifting plate inserted into a space between adjacent conveyer belts; multiple rows of multi-layer conveyer belts can be arranged on the same frame; and the machine head is driven by a speed regulating motor. In the invention, the motion characteristic of a shaking table is organically combined with a cross flow belt concentrator, and a revolving gear at the bottom of the frame is eliminated, so that a combination effect is achieved by using two motion characteristics. By adopting the concentrator, the concentrating indexes of heavy metal ores such as tin, tungsten, lead and the like of over 10 microns can be greatly increased, the concentration belt separation is very remarkable, the recovery ratio is up to 85 percent in maximum, the concentration ratio is as high as 10-40 times, and the handling capacity is 10-25 tons/set.

Description

technical field [0001] The invention relates to a mineral processing equipment, a shaker type cross-flow belt mineral processing machine. Background technique [0002] Shaking table and belt concentrator (also known as belt chute), especially cross-flow belt concentrator, although the slurry flow direction is roughly the same as that of the shaking table, the way and direction of the force on the ore particles are very different. The shaker is a gravity beneficiation equipment that has been used for hundreds of years. The technology is mature, but the disadvantages of the shaker are: the processing capacity is small when the fine-grained ore is sorted, the recovery rate is low, and the bed will overflow when the processing capacity increases. Mineral materials are piled up, and the sorting index drops; in addition, the amount of wood used in the shaking table is large, and the bed surface is easy to scale or deform and damage, which requires regular maintenance and high oper...

Problems solved by technology

The shaker is a gravity beneficiation equipment that has been used for hundreds of years. The technology is mature, but the disadvantages of the shaker are: the processing capacity is small when the fine-grained ore is sorted, the recovery rate is low, and the bed will overflow when the processing capacity increases. Mineral materials are piled up, and the sorting index drops; in addition, the amount of wood used in the shaker is large, and the bed surface is easily scaled or deformed and damaged. Regular maintenance is required, and the use cost is high.
