Problems solved by technology

[0004] The purpose of the present invention is to solve the above-mentioned problems and provide a simple and compact vibrating magnetic separator for mines with a small footprint. The vibrating plate and magnetic separation equipment are combined to expose the magnetic materials in the minerals. It is absorbed by the magnetic system on the surface, which greatly improves the absorption rate of magnetic materials in minerals. It mainly solves the problems of low recovery rate of some weak magnetic ore particles and low concentrate grade in existing magnetic separators, improves the beneficiation efficiency, and solves the problem of magnetic The non-magnetic parts of the separator are magnetized, and at the same time improve the adaptability of the magnetic separator and enhance the corrosion resistance of the magnetic separator

Abstract

The invention discloses a vibration type magnetic separator for a mine, and belongs to the technical field of mine machinery. The vibration type magnetic separator for the mine comprises a frame, wherein the frame is provided with an inclined vibration flowing plate; the vibration flowing plate is arranged on the frame through a vibration spring; a vibration exciter is arranged on the bottom surface of the vibration flowing plate; magnetic separation equipment is arranged above the lower end of the vibration flowing plate; a nonmagnetic ore port and a magnetic ore port are formed in the tail end of the vibration flowing plate; and the magnetic ore port is aligned to an ore polishing place of the magnetic separation equipment. The vibration type magnetic separator for the mine is simple and compact, and is small in floor area; and the vibration plate and the magnetic separation equipment are combined, so that a magnetic material in a mineral is exposed on the surface and absorbed by a magnetic system, and the absorptivity of the magnetic material in the mineral is greatly improved.

Description

technical field [0001] The invention relates to the technical field of mining equipment, in particular to magnetic separation equipment for mining. Background technique [0002] At present, the magnetic separators used to process magnetite-type iron ore are generally drum-type magnetic separators. Because the drum of the drum-type magnetic separator needs to rotate continuously, and the magnetic system in the drum must remain fixed, Therefore, there is a gap between the magnetic system and the inner wall of the drum, which weakens the magnetic field strength of the outer wall of the drum, so that the magnetic energy of the magnetic system cannot be fully utilized. Magnetic separators, especially strong magnetic separators, are seldom used in ilmenite beneficiation operations. Generally, only weak magnetic ones are used for iron removal of ilmenite ore materials, while sand-titanium ore is beneficiated with spiral rollers, which has poor adaptability and low recovery rate. A...
