A new type of high-efficiency continuous concentrator

Abstract

The invention relates to the field of ore beneficiation equipment, in particular to a novel high-efficiency continuous ore beneficiation machine which comprises a main barrel, a centrifugal drum, a feed pipe, an air supply system and an ore concentrate drain-off system. The centrifugal drum is arranged in the main barrel; multiple separation grooves are formed in the centrifugal drum; multiple oreconcentrate discharge pipes are arranged on the inner walls of the separation grooves; open-close devices are arranged at the downstream ends of the ore concentrate discharge pipes; the ore concentrate drain-off system comprises multiple power pieces; the cross section of the centrifugal drum is in an inverted trapezoidal structure; the inclined direction of each power piece is the same as the inclined direction of a waist edge of the cross section of the centrifugal drum; each power piece is in transmission connection with the open-close device corresponding to the power piece; the feed pipeis arranged in the centrifugal drum; a hydraulic lifting system is arranged at the upper end of the feed pipe; the air supply system is arranged on the bottom part of a separation barrel; and the separation barrel is arranged on the periphery of the centrifugal drum. According to the novel high-efficiency continuous ore beneficiation machine provided by the invention, ore concentrates can be stably discharged in real time, and the simultaneous discharge rate of ores to be beneficiated and the ore concentrates is reduced.

Description

technical field [0001] The invention relates to the field of mineral processing equipment, in particular to a novel and efficient continuous mineral processing machine. Background technique [0002] The ore concentrator is mainly used for the beneficiation of gold, silver, tin, manganese, tungsten, iron, shaft, rare earth and other elements. As we all know, the current general-purpose discontinuous ore-discharging drum type centrifugal concentrator is the only thin-flow film concentrator that mainly relies on centrifugal force; modern centrifugal concentrators can be divided into two types, namely horizontal centrifugal concentrators and vertical centrifugal concentrators. Concentrator. The drum of the centrifugal concentrator rotates at a high speed at a certain number of revolutions, and the ore pulp is sent to the inner wall of the drum by the ore feeder through the feed nozzle in two places. The pulp rotates with the drum at high speed. Under the action of centrifugal ...

Problems solved by technology

[0004] The disadvantage of the above scheme is that the cut-off valve used does not specify what kind of valve body it is, and according to the traditional valve body on the market, it is a spring return structure. The valve can only be opened stably, but due to the centrifugal force, the divergent expansion of the water is caused. Whether the valve of the valve body can be automatically reset is a problem; The concentrate is produced by a sorting cycle. In the non-stop state, the valve is opened and the concentrate is discharged. The real-time injection of the ore to be selected and the concentrate may be mixed, and there may be a high probability that the two will be discharged at the same time. The problem
