A wear-resistant and anti-clogging permanent magnet wet coarse pre-selection magnetic separator

Abstract

The invention discloses a wear-resisting blocking-resisting permanent magnet wet type coarse particle preconcentration magnetic separator which comprises an ore feeding device, a tank (7), a barrel (1), a driving device of the barrel, a magnetic system (8), a magnetic regulating device (10), an ore unloading flushing water pipe (9), a concentrate box (4) and a rack (3). The ore feeding device is formed by combining a mixing pool (6), an ore feeding water pipe (13) and an ore feeding hopper (12). A water outlet of the ore feeding water pipe (13) is located in the mixing pool (6), and the ore feeding hopper (12) is of a dustpan-shaped structure. The magnetic wrap angle of the magnetic system (8) ranges from 130 degrees to 145 degrees. A vulcanized rubber composite bonding ceramic sheet is arranged on the surface of the barrel (1). A forced ore unloading device (5) is arranged in the concentrate box (4), and a spiral forced conveying structure is adopted in the forced ore unloading device (5). A magnetic field work area is divided into a preconcentration area, a separation area and an ore unloading area. By means of the wear-resisting blocking-resisting permanent magnet wet type coarse particle preconcentration magnetic separator, ore can be evenly and loosely fed to the surface of the barrel, the situation that the tank is blocked due to mineral sedimentation is not prone to happen, the wear resisting capacity of the tank and the barrel is high, and high-magnetic minerals can be effectively caught.

Description

technical field [0001] The present invention relates to a permanent magnet wet-type drum magnetic separator, in particular to a downstream permanent magnet coarse-grain pre-selection waste magnetic separator, which is used for wet pre-selection of strong magnetic materials with a particle size of 0~15mm before entering the mill. Magnetic separation work. Background technique [0002] With the severe situation of mines in recent years, the cost of mining and beneficiation of foreign iron ore is low, while the cost of mining and beneficiation of extremely poor iron ore resources with a large amount of storage in my country is high, which cannot withstand the price impact of foreign mines. Therefore, energy saving, consumption reduction, Efficiency enhancement is the development trend of mineral processing plants, and an important way to save energy, reduce consumption, and increase efficiency is to break more and grind less, and pre-select waste. [0003] In order to implement...

Problems solved by technology

This magnetic separator partially solves the wear resistance of the cylinder and the clogging of the tank, but there are still the following problems: although it contains the ore feeding box and the ore feeding chute, the pulping process is lacking or the pulping is not sufficient, and the fed The material agglomeration phenomenon is serious, which is not conducive to ore feeding and separation; although the tank body has a recoil suction pipe, the slurry is still easy to block the tank body, because the coarse particle material stays on the arc plate for a long time, has poor fluidity, and is easy to settle; Although the body is bonded to the ceramic sheet, it is easy to fall off. The reason is that the bonding strength of the adhesive will become worse and worse in the harsh environment, and the problem of the wear of the tank body is still not solved.
