Wind permanent magnet concentrator

Abstract

The invention discloses a wind power permanent magnetism dressing machine. The dressing machine comprises a machine shell and a permanent magnetic pulley. The permanent magnetic pulley is arranged in the machine shell. An air inlet is arranged at the lower part of one side of the machine shell, and an air outlet is arranged at the lower part of the other side of the machine shell. The air inlet and the air outlet are arranged to be staggered highly and lowly. Adjustable flow deflectors are hinged to the upper end of the air inlet and the lower end of the air outlet respectively. The adjustable flow deflectors are arranged in the positions corresponding to the air inlet and the air outlet in the machine shell, and the dressing machine can adjust air inlet volume of a feed inlet and air outlet volume of a feed outlet through adjustment of inclination angles of the adjustable flow deflectors. In the premise of ensuring ore powder not being blown out from the air outlet, the non magnetic particles in the ore powder are blown out from the air outlet, and the separation efficiency is more than 98%. The dressing machine solves the problems of high water consumption, high electricity consumption and low separation efficiency during wet ore dressing process in the prior art The dressing machine reduces the ore dressing cost, does not need to build tailing ponds, and guarantees life safety of workers greatly.

Description

technical field [0001] The invention relates to mineral processing equipment, in particular to a wind-powered permanent magnetic mineral separation machine. Background technique [0002] my country's raw ore output ranks first in the world, but most of them are lean ore, and the amount of equivalent metals accounts for a low proportion of the world's output. According to the survey data of the Geological Survey Bureau, the global raw ore output is about 2 billion tons, and China's raw ore output is about 6 billion tons, accounting for about 30% of the global output. From the perspective of the variety and quality of raw ore, domestic raw ore resources are characterized by poverty, miscellaneous and fine. [0003] At present, most of the ore dressing methods in mines use wet beneficiation. The process of wet beneficiation consumes a lot of water and electricity. The highest separation can only reach about 85%, and the efficiency is low. The tailings after wet beneficiation hav...

Problems solved by technology

[0003] At present, most of the ore dressing methods in mines use wet beneficiation. The process of wet beneficiation consumes a lot of water and electricity. The highest separation can only reach about 85%, and the efficiency is low. The tailings after wet beneficiation have a high water content. The treatment method is to build a tailings pond with a height of tens of meters to hundreds of meters for storage according to the terrain of the mine. The maintenance of the tailings pond requires a lot of manpower and material resources, and the tailings pond is easy to collapse and wet The method of mineral processing not only destroys the geology and environment, but also causes serious safety hazards to the safety of workers. In order to solve the serious energy consumption of wet mineral processing and the need to build tailings ponds, a permanent magnetic mineral processing machine is used for mineral processing. Permanent magnetic Due to the low dispersion of the minerals fed into the type concentrator, there are too many non-magnetic particles in the concentrate, and the separation efficiency is still not high. Therefore, a safe, water-saving and power-saving mineral processing equipment with high separation efficiency It has become the common vision of relevant personnel in the mineral processing industry
