Trough body for high-efficiency permanent magnet drum magnetic separator

Abstract

The invention discloses a trough body for a high-efficiency permanent magnet drum magnetic separator, comprising a trough body, wherein the trough body is provided with an ore-feeding inlet at the upper part of one lateral surface and a tailing outlet at the lower part of the lateral surface and corresponds to a high-efficiency permanent magnet drum. In addition, the trough body adopts a semi-reverse current form. The trough body is characterized in that an ore inlet communicated with the ore-feeding inlet is arranged on the bottom surface in the trough body; an overflow port communicated with the tailing outlet is arranged on a slope surface in the trough body, which is positioned at the same side with the ore-feeding inlet; a coarse particle discharge hole communicated with the tailing outlet is formed in the trough body at the lower part of the overflow port; an ore concentrate outlet is arranged at the upper part of the slope surface of the trough body on the lateral surface opposite to the ore-feeding inlet; and a spraying device jetting to the permanent magnet drum is arranged in the trough body. The invention has the advantages of high overflow weir and long sorting band for delaying the sorting time. In addition, with the coarse particle prior discharge hole, the phenomenon that ore is blocked in the trough body can be effectively prevented. Spraying tubes are arrangedin an ore unloading area, so that ore concentrate sundries can be removed and the ore concentrate grade can be improved. The invention also has the characteristics of simple and reasonable structure,simple and convenient operation, long service life and the like.

Description

Technical field [0001] The invention relates to the technical field of high-efficiency magnetic separation equipment, in particular to a tank for a high-efficiency permanent magnet drum type magnetic separator. Background technique [0002] As we all know, magnetic separation equipment is an important separation equipment in the process of iron metal separation in mines. At present, there are two main types of magnetic separation equipment used in mines. One is disc magnetic separation and the other is drum magnetic. selected. With the continuous development of science and technology, in order to improve production efficiency, large-scale magnetic separation equipment is becoming larger, and the performance of professional magnetic separators designed for the magnetic separation operating environment is constantly improving. In response to the requirements of the high-efficiency permanent magnet cylinder magnetic separator sorting operation, it is necessary to have a deeper magn...

AI Technical Summary

Problems solved by technology

In view of the requirement of high-efficiency permanent magnet drum magnetic separator for sorting operation, it is necessary to have a deep magnetic field with a high depth gradient in the sweeping area, so as to ensure that it can complete the complete recovery of strong magnetic minerals under the condition of large flow, and At present, the trough body for permanent magnetic drum magnetic separators on the market has defects due to its own structure, such as: for the requirements of high-efficiency permanent magnetic drum magnetic separators for sorting operations, the pulp throughput is 800m 3 ~1200m 3 / h, corresponding to the large wrap angle of the equipment and the characteristics of the long separation zone, a high overflow weir is configured to increase the residence time of the slurry; at the same time, the inclusion of concentrate is more obvious in the separation operation, and it is necessary to deal with the inclusion phenomenon to reduce the inclusion Improve concentrate grade
