Water standing wave shaking table and beneficiation method

Abstract

The invention discloses a water standing wave shaking table and a beneficiation method. The water standing wave shaking table includes a machine frame, a shaking table body supporting driving mechanism and a shaking table body. The shaking table body supporting driving mechanism comprises a driving motor, a speed reducer, polished rods, active sliding sleeves, passive sliding sleeves and deflection mechanisms; the polished rods, the active sliding sleeves, the passive sliding sleeves and the deflection mechanisms are in symmetrical arrangement. The polished rods are fixedly connected with themachine frame. The active sliding sleeves and the passive sliding sleeves slidably sleeve the polished rods. The tops of the active sliding sleeves are hinged to the shaking table body, an adjustingmechanism is arranged between the passive sliding sleeves and the shaking table body, and each deflection mechanism includes an eccentric disc and a crank connected with the eccentric disc. The cranksare hinged to the active sliding sleeves, the speed reducer is provided with two output shafts, each output shaft is connected with the corresponding eccentric disc. The water standing wave shaking table is simple in structure and convenient to operate, can recover fine-grained heavy metal particles and is high in recovery efficiency and beneficiation efficiency, no chemical agent is added duringthe beneficiation process, no harm is caused to the environment, and the water standing wave shaking table has broad promotion value.

Description

technical field [0001] The invention relates to a water standing wave shaker and a mineral processing method, belonging to the technical field of mineral processing equipment. Background technique [0002] The shaking table is one of the important equipment for mineral processing. It is a gravity mineral processing equipment for separating fine-grained materials. coal etc. [0003] The ore beneficiation process of the traditional shaking table is carried out on the inclined bed surface. The inclined bed surface is engraved with grooves. Under the action of gravity, horizontal flow force, inertia and friction caused by the reciprocating asymmetric motion of the bed surface, it is stratified according to specific gravity and particle size, and moves longitudinally along the bed surface and laterally along the inclined bed surface. Therefore, the ore particles with different specific gravity and particle size gradually flow down from the mineral filling side to the opposite s...

AI Technical Summary

Problems solved by technology

The traditional shaking table recovers heavy metal particles with a particle size of 2-0.037mm, the recovery rate is not high, and the efficiency is relatively low

Among them, there is also a standing wave shaker in the existing gravity beneficiation equipment, whose vibration track is the direction of rotation, and the sorting particle size is relatively wide, and it is impossible to accurately sort fine-grained materials; for gold particles with a recovery particle size of less than 0.1mm, existing The leaching or flotation process is often used in mineral processing operations. Due to the complexity of the leaching and flotation process and the need to add chemicals, it will endanger the environment and the cost is high
