Multistage pyrite water-saving sawtooth wave jig gravity separator

Abstract

The invention provides a multi-stage pyrite water-saving sawtooth wave jigging gravity selection machine. The multi-stage pyrite water-saving sawtooth wave jigging gravity selection machine comprisesjigging boxes which are each of a V-shaped structure with an upward opening and is internally filled with medium water, a discharging device and a power driving device, wherein the jigging box is composed of a first jigging box and a second jigging box which are symmetrically arranged left and right, the first jigging box is used for receiving a mixture of pyrite and waste rock monomer and carrying out concentrate reselection, the second jigging box is used for carrying out secondary concentrate reselection on the mixture of the pyrite and the waste rock monomer and discharging tailings, and aconveying mechanism for connecting the opening of the first jigging box and the opening of the second jigging box is arranged between the opening of the first jigging box and the opening of the second jigging box; and an agitation mechanism used for vibrating the inner medium water is arranged on the side face, close to the bottom, of the jigging box, the discharging device is used for dehydrating and discharging the concentrate deposited at the bottom of the jigging box, and the power driving device is used for providing driving power for the conveying mechanism, the agitation mechanism andthe discharging device.

Description

technical field [0001] The invention relates to a mineral dressing jigging machine, in particular to a multistage pyrite water-saving sawtooth wave jigging re-separator. Background technique [0002] The hydraulic jigging gravity separator is a gravity beneficiation process that uses the vertical alternating water flow caused by strong vibration to layer the ore particles according to the relative density and collect light and heavy minerals separately by appropriate methods to achieve the purpose of separation. During the process, the pyrite raw ore is crushed by the crusher to the optimum particle size for the rod mill, and then transported to the rod mill for grinding by the belt conveyor, so that the pyrite and waste rock are separated, and the pyrite and waste rock The single-head mixture is conveyed to the hydraulic jig by a belt conveyor for gravity separation, and the concentrate (pyrite) and tailings (waste rock monomer and a small amount of pyrite) are obtained fro...

AI Technical Summary

Problems solved by technology

[0003] At present, the common sheet of the existing hydraulic jigging gravity separator makes the water medium vibrate in a sawtooth wave through the agitation of the diaphragm at the bottom of the jigging chamber. Since the diaphragm needs to overcome the pressure and gravity of the medium water, each diaphragm is driven by a separate motor Agitation has the disadvantages of high energy consumption, high pressure on the diaphragm and easy damage; and when separating the concentrate, it is necessary to discharge the medium water in the jigging chamber, which has the disadvantage of wasting water resources. In order to overcome the above-mentioned Deficiency, the inventor designed a super pyrite water-saving sawtooth wave jigging re-separator with ingenious structure, simple principle, single motor and double jigging chamber, capable of continuous pyrite ore separation, and high beneficiation efficiency
