Rotational flow material distribution device for classificator

Abstract

The invention relates to the field of mineral processing equipment, and particularly relates to a rotational flow material distribution device for a classificator. The rotational flow material distribution device is arranged above a sorting barrel of the classificator and comprises a material distribution outer barrel and a swirler, wherein the swirler is positioned in the material distribution outer barrel; a first overflow opening is formed in the top of the swirler; a bottom flow opening is formed in the bottom of the swirler; a feeding opening of the swirler extends out of the material distribution outer barrel through a feeding pipe; and a second overflow opening is formed in the material distribution outer barrel. The rotational flow material distribution device further comprises a material distribution mechanism for receiving ore pulp materials, an auxiliary water supplementing mechanism for diluting the ore pulp materials and a material flow controller for controlling the flowof the ore pulp materials, wherein the auxiliary water supplementing mechanism penetrates the material distribution outer barrel and is connected with the material distribution mechanism; and the material flow controller is positioned in the material distribution outer barrel and controls the flow of the ore pulp materials at the bottom of the swirler. The rotational flow material distribution device has the effects that the sorting effect of the classification work is improved, and the work burden of subsequent classification is relieved.

Description

technical field [0001] This application relates to the field of mineral processing equipment, in particular to a swirling flow distribution device used on a concentrator. Background technique [0002] The sorting operation of magnetite is mostly carried out by column type concentrator to improve the grade. Column concentrator is a new type of beneficiation equipment that uses alternating magnetic force, gravity and the impact of reverse water to separate high-grade ferromagnetic minerals from low-grade gangue minerals. [0003] At present, the concentrator in use only has a cyclone, and the high-grade and low-grade pulp materials are processed through the cyclone. This kind of separation efficiency is low only relying on the cyclone, and at the same time, the low-grade pulp material overflowed from the cyclone It will contain high useful elements, which will cause waste of resources, low recovery rate of pulp materials, and poor sorting effect. [0004] In view of the abov...

[0003] At present, the concentrator in use only has a cyclone, and the high-grade and low-grade pulp materials are processed through the cyclone. This kind of separation efficiency is low only relying on the cyclone, and at the same time, the low-grade pulp material overflowed from the cyclone It will contain high useful elements, which will cause waste of resources, low recovery rate of pulp materials, and poor sorting effect

[0004] In view of the above-mentioned related technologies, the inventor believes that there are defects such as high separation of concentrators, poor effect of low-grade mineral materials, and low efficiency
