Pneumatic concentrating machine

Abstract

The invention discloses a pneumatic concentrating machine especially suitable for sorting of mica. The lower portion of a machine body of the pneumatic concentrating machine is provided with a support. The machine body is internally provided with a motor. The motor is in shaft connection with a draught fan. The motor is connected with a frequency converter. An air outlet of the draught fan communicates with an air chamber through an air inlet pipe. The air chamber is located on one side of a sorting chamber. A grid is located on the other side of the sorting chamber. The grid and the air chamber are located on the same horizontal line. The sorting chamber is internally provided with a tapered material distribution hopper. The top of the tapered material distribution hopper is provided witha material distribution adjusting plate. The top of the sorting chamber is provided with a feeding adjusting plate. The two sides of the bottom of the sorting chamber are provided with a concentratesurge bunker and a gangue surge bunker correspondingly. The pneumatic concentrating machine is large in sorting particle size range, intensive in sorting process, high in sorting efficiency, capable of reducing product impurities and increasing the recovering rate, capable of sorting mica and other ores and suitable for agriculture, the light industry, waste recovering and other different fields.

Description

technical field [0001] The invention relates to mineral processing equipment, in particular to a wind-powered mineral processing machine, which is especially suitable for mica separation and belongs to the technical field of mining machinery and equipment. Background technique [0002] Wind beneficiation belongs to gravity beneficiation method. For a long time, gravity beneficiation has mostly been based on wet gravity separation (with water as the medium). Wet gravity separation equipment not only has many types, strong adaptability, but also has better and better performance. But at the same time, wind power beneficiation without water has always been a field of exploration. [0003] Wind beneficiation is the process of separating mineral raw materials according to the difference in mineral density in the air medium. The particle size and shape of the particles also affect the separation. Compared with wet gravity separation in water medium, wind power dressing does not ...

AI Technical Summary

Problems solved by technology

Shape beneficiation is based on the different shapes of mica crystals and gangues, and the ability to pass through the sieve gaps and holes of the sieve during screening, so that mica and gangues are separated; Sieve; its disadvantage is that heavy minerals and light minerals are not easy to separate, and the phenomenon of mineral mixing is serious

[0007] To sum up, the traditional mica beneficiation methods and equipment mainly have the following two major problems: 1. It is only suitable for minerals with large particle size, resulting in serious waste of resources, low production capacity, low recovery rate, and high cost; 2. Processing The quantity is small, the equipment is large, the process is discontinuous, and it is difficult to large-scale and large-scale production, resulting in irregular replacement of consumables, high work intensity, and high sorting costs
