Problems solved by technology

Although they have solved the problem of continuous ore discharge of concentrate and have the advantages of high separation index, they have not been widely used so far due to the disadvantages of high water consumption, high energy consumption, the need to add water purification devices and poor mechanical stability.
Although the separation effect of the multi-gravity concentrator (MGS) is good, the discharge method of the concentrate is to use a mechanical scraper to discharge the ore, which makes the equipment structure complicated, the scraper wears a lot, and the price is expensive.
To sum up, the main disadvantage of the existing horizontal centrifugal beneficiation equipment is that either it can only feed ore intermittently and discharge ore, and cannot run continuously; or it can run continuously, but the problem of continuous discharge of concentrate is not well solved

Abstract

A chute-type centrifugal ore dressing machine features that several groups of tapered chutes are axially installed round a horizontal rotary axle in the bottom-to-bottom mode. When the ore sludge flows through the chutes, the chutes in rotating around the axle at high seed. The generated centrifugal force can deposit the high-density mineral on the bottom of chutes and then discharge it.

Description

Technical field [0001] The invention relates to wet gravity mineral processing equipment, in particular to a horizontal rotary tapered chute type centrifugal mineral processing machine which relies on a composite force field mainly for centrifugal force field for mineral processing and automatically discharges ore by centrifugal force. Background technique [0002] Wet gravity beneficiation method refers to the beneficiation method in which crushed ore is separated from light and heavy minerals by relying on the different gravity of particles with different densities to have different settling velocities in the slurry system with water as the medium. The traditional gravity beneficiation method mainly relies on the effect of the gravity field, so the separation efficiency is relatively low, the processing capacity is small, and the scope of application is limited. Especially for fine particles, such as particles smaller than 19 microns, gravity alo...
