Problems solved by technology

[0002] At present, the domestic metallurgical industry and metallurgical plants in various industries have developed rapidly and have reached the world's advanced level. However, the production and processing methods of metal ore powder, one of the metal raw materials, are still relatively backward, resulting in backward metal ore powder processing technology. Low output, high environmental pollution, and a large waste of water resources have brought huge economic losses to the country and mines. Today's domestically produced metal ore powder cannot meet the production needs of major metallurgical plants.

Abstract

The invention relates to a pneumatic concentrator, belonging to the field of mine-selecting equipment. The pneumatic concentrator provided by the invention has high output, low cost, high yield and environmental protection. The pneumatic concentrator comprises a powder grinding machine, a mineral separation bin, a spiral propeller and a material storage bin which are sequentially connected by feed pipes, wherein a dust removing machine is provided with a fan and an air compressor on the feed pipe between the powder grinding machine and the mineral separation bin; and the mineral separation bin is provided with an air hole band.

Description

technical field [0001] The invention belongs to the field of mineral processing equipment, in particular to a metal ore used for selecting the specific gravity of enriched elements in the ore is higher than that of other impurities in the ore. Background technique [0002] At present, the domestic metallurgical industry and metallurgical plants in various industries have developed rapidly and have reached the world's advanced level. However, the production and processing methods of metal ore powder, one of the metal raw materials, are still relatively backward, resulting in backward metal ore powder processing technology. Low output, high environmental pollution, and a large waste of water resources have brought huge economic losses to the country and mines. Today's domestically produced metal ore powder cannot meet the production needs of major metallurgical plants. Contents of the invention [0003] The present invention aims at the above-mentioned problems, and provides...
