Elutriation Magnetic Separator

Abstract

The invention provides an elutriating magnetic separator, belonging to the technical field of mineral separation, comprising a sorting cylinder, an overflow device, a feeder and a water supply structure, the outer wall of the sorting cylinder is provided with a magnetic structure; the overflow device is located on On the sorting tube, and communicated with the sorting tube, it is used to discharge tailings. There is a movable or deformable first adjustable balance structure on the inside of the overflow and / or outside the feeder, which is used to change the size of the overflow. The size of the overflow surface; the feeder is arranged above the overflow device; the water supply structure is located below the sorting cylinder and communicates with the sorting cylinder; the elutriation magnetic separator provided by the invention can be selected according to the characteristics of the minerals, Properly adjust the size of the adjustable balance structure, change the size of the overflow surface of the overflow tank, so as to change the rising water velocity in the overflow tank, thereby changing the buoyancy of the solid particles with different particle sizes and densities in the overflow tank slurry, to achieve the best The separation effect is good, the concentrate grade is improved, the recovery rate is increased, and the amount of flushing water at the bottom can be reduced to save water.

Description

technical field [0001] The invention belongs to the technical field of magnetic mineral separation equipment, and more specifically relates to an elutriation magnetic separator. Background technique [0002] With the continuous improvement of metallurgical enterprises' requirements for product quality, economic benefits, equipment efficiency, energy consumption, and environmental protection, their requirements for the quality of furnace concentrates are also getting higher and higher. Whether ore can provide smelting enterprises with high-quality ore concentrate at a lower cost is the key to improving economic benefits for beneficiation enterprises. The ores in the concentrator usually come from multiple mines, and the characteristics of the selected minerals, such as magnetism and particle size, are different. Therefore, the elutriation magnetic separator with fixed structural parameters is set. When the characteristics of the selected minerals change It is difficult to ob...
