High-efficiency permanent magnet drum magnetic separator

Abstract

The invention relates to a high-efficiency permanent magnet drum magnetic separator which comprises a stander, a tank, a roller, a magnetic system and a drawing template device, and has the technical key points: an output end of a transmission control part is connected with a transmission driving shaft on a permanent magnet roller, the magnetic system is arranged on a fixed bracket at the inner side of the permanent magnet roller, magnetic system wrap angle corresponding to a sorting belt is 120-140 degrees, the number of magnetic poles can be 7-12, the drawing template device is arranged on a stander which is separated from the magnetic system and close to the outer surface of the permanent magnet roller, and the tank is also provided with an ore back flushing device used for preventing ore slurry from precipitating. The useful effect depth of scavenging area magnetic field of the magnetic system reaches 110mm, the processing capacity of unit length along the axial direction of a permanent magnet cylinder is large, and the recovery rate of magnetic mineral is high. Concentrated ore can be unloaded by a drawing template, so that the water-saving effect is remarkable compared with the traditional rinse water ore unloading way. A rinsing device is arranged for washing the concentrated ore, thus further removing the impurities in the concentrated ore. The invention has the characteristics of good sorting effect, high concentrated ore quality, simple structure, convenient maintenance, long service life, etc.

Description

Technical field [0001] The invention relates to the technical field of mining equipment, in particular to a high-efficiency permanent magnet cylinder magnetic separator used for large-scale high-efficiency magnetic separation equipment for mineral processing. Background technique [0002] As we all know, the magnetic separator is the universal magnetic separation equipment in the concentrator. In recent years, the grade of the original ore of large-scale mining of ore is getting lower and lower, and the particle size of the mineral embedded is getting finer and finer. Due to the defects of the current permanent magnetic separator's own structure, the separation effect of the mineral after fine grinding is not good. At the same time, large-scale concentrators have exposed the problem of insufficient processing capacity of a single machine. Therefore, the market will be more urgent to develop large-scale and efficient permanent magnet separation equipment. Summary of the invention...

Problems solved by technology

In recent years, the raw ore grade of large-scale mining of ore is getting lower and lower, and the particle size of mineral embedding is getting finer and finer. Due to the defects in the structure of the current permanent magnet magnetic separator, the separation effect of minerals after fine grinding is not good. At the same time, large-scale concentrators have exposed the problem of insufficient processing capacity of a single machine. Therefore, it will be more urgent to develop large-scale and efficient permanent magnetic separation equipment in the market.
