Magnetic separator

Abstract

Disclosed is a magnetic separator. The magnetic separator comprises a machine frame, a rotating ring, a horizontal rotating drive mechanism and an exciting device which is arranged on the machine frame and used for generating a horizontal separation magnetic field. A medium mixing box is arranged on the rotating ring. A water-vapor combined washing device used for washing and discharging the medium mixing box from the side face is arranged beside the rotating ring. Materials are fed from the upper end face of the rotating ring and are further discharged out of the lower end face of the rotating ring after separation. The feeding and discharging direction is perpendicular to the washing and discharging direction. By adoption of the structure that the feeding and discharging direction is perpendicular to the washing and discharging direction, as long as the thickness (washing and discharging depth) of the medium is unchanged, the sorting height of the medium box can be designed accordingto the magnetic property requirements of sorted substances without affecting the washing and discharging effect of the medium box, stable and continuous operation of equipment is guaranteed, and blocking can be avoided; the sorting gradient is increased by using the medium mixing box, and the grading effect is effectively improved; and the moisture content of the discharged substances is effectively lowered through the water-vapor combined washing device on the side face, the follow-up treatment difficulty is lowered, and reliable and practical technical equipment is provided for sorting weakly magnetic substances.

Description

technical field [0001] The invention relates to a continuous high-gradient magnetic separator, in particular to a horizontal side flushing high-gradient magnetic separator for sorting weak magnetic substances. Background technique [0002] Continuous high-gradient magnetic separators are divided into vertical ring high-gradient magnetic separators and horizontal high-gradient magnetic separators. Widely used in mining enterprises and sewage treatment enterprises at home and abroad, it is one of the most important equipment for wet separation of weak magnetic substances. [0003] In recent years, with the gradual depletion of mineral resources in my country and the world, the price of mineral resources has continued to rise, and more and more low-grade weak magnetic mineral resources (iron ore, manganese ore, etc.) are urgently needed to be developed and utilized; on the other hand, industrialized Development has higher and higher requirements for products, and it is more and...

AI Technical Summary

Problems solved by technology

This structure increases the height of the feeding and discharging direction (magnetic media sorting height). Although the sorting effect is improved, it will cause the flushing and discharging height to increase at the same time, and it is difficult for the flushing water to penetrate through the thick media box effectively. There are more and more residual magnetic substances, the sorting effect of the equipment is getting worse and worse, and even the media box is blocked, which seriously affects the normal operation of the equipment and the sorting efficiency

Moreover, the mixed arrangement of magnetic permeable materials in the direction of the separation height of magnetic media in this structure will also increase the difficulty of washing and unloading

In addition, the existing flushing and unloading method has a high water content in the unloaded material, which is not conducive to subsequent processing
