Hyperfine high-gradient magnetic separator

Abstract

The invention relates to the technology of beneficiation machinery, in particular to a hyperfine high-gradient magnetic separator which is suitable for deironization and extraction of non-metal minerals and beneficiation of weak magnetic minerals. The hyperfine high-gradient magnetic separator comprises a main body equipment part and a rectifying control cabinet part, and the main body equipment part comprises a main body support, a magnet yoke, a magnet exciting coil and a magnetic medium box, wherein the magnet yoke is arranged on the upper part of the main body support; the magnet exciting coil is arranged around the magnet yoke; the magnetic medium box is arranged at a gap of the centre of the inner side of the magnet yoke, and the upper part of the magnetic medium box is connected with a vibration mechanism; pipe systems for enabling ore pulps to flow in and flow out and washing water to flow in and flow out are arranged at the two sides of the exterior of the magnet yoke; the pipe systems comprise various pneumatic valves, electromagnetic valves and ball valves; the pipe systems are connected with the magnetic medium box; and the rectifying control cabinet part comprises an excitation magnet and an breakage magnet, as well as a control system, wherein the excitation magnet and the breakage magnet are used for controlling the magnet exciting coil, and the control system is used for controlling actions and resetting of each valve in the pipe system, and controlling error alarming and resetting. The invention is the most ideal non-metal deironization equipment which has the advantages of strong mine-feeding granularity, concentration and grade fluctuation adaptability, reliable work and convenient operation and maintenance.

Description

technical field [0001] The invention relates to mineral processing machinery technology, in particular to an ultra-fine high-gradient magnetic separator suitable for iron removal and purification of non-metallic minerals and mineral processing of weakly magnetic minerals. Background technique [0002] The current general non-metallic iron removal equipment can only remove mechanical iron or coarse-grained strong magnetic minerals; or the processing capacity in the beneficiation operation is small, which cannot meet the demand for high production capacity; Less than fine iron removal requirements. Contents of the invention [0003] The purpose of the present invention is to improve and innovate the shortcomings and problems existing in the background technology, and to provide a non-metallic iron removal equipment that can not only meet the requirements of large batch processing, but also achieve ultra-fine processing, and has a wide range of applications and high beneficia...
