Dense medium ore sorting equipment

Abstract

The invention discloses dense medium ore sorting equipment, and belongs to the field of beneficiation equipment. The dense medium ore sorting equipment comprises a sorting cylinder body (5), a movablescreen plate (1), a fixed screen plate (2) and a lifting device (3), the fixed screen plate (2) is arranged at a discharging port of the sorting cylinder body (5), the movable screen plate (1) is arranged in the sorting cylinder body (5), moreover, the lifting device (3) can drive the movable screen plate (1) to move up and down, dense medium chain strings (4) are arranged at the lower end of themovable screen plate (1) at intervals, one ends of steel ropes (43) of the dense medium chain strings (4) are connected with the end surface of the movable screen plate (1), and dense medium balls (41) are arranged on the steel ropes (43) in a penetrating and sleeving mode. According to the dense medium ore sorting equipment, the principle that light minerals and heavy minerals generate floatingand sinking and jigging ore dressing phenomena in a heavy suspension liquid is adopted, the lifting device (3) drives the dense medium chain strings (4) to do vertical movement so as to realize transverse uniform distribution of dense media at the sorting cylinder body (5) or in the cylinder body, then the dense media can not precipitate in the up-and-down movement, and the purpose of screening ores is realized.

Description

technical field [0001] The invention discloses a dense medium ore sorting device, which belongs to the field of mineral processing equipment. Background technique [0002] Before extracting the valuable minerals in the ore, it needs to be crushed. The crushed ore needs to be screened, and the ore particles with qualified particle size are screened out, and then the ore beneficiation method is gravity separation, magnetic separation, flotation, electric Beneficiation and chemical beneficiation, and sorting to obtain useful concentrates. [0003] Dense medium means that the density is greater than 1g / cm of water 3 heavy liquid or heavy suspension fluid. The process of sorting ore particles in dense media is called dense media beneficiation. The dense medium beneficiation method is a kind of gravity separation method, which is a method of mineral separation strictly according to density. Its basic principle is Archimedes' principle - particles less than the density of the d...
