Problems solved by technology

However, the core working principle of this type of equipment is based on the fact that the pulsation direction of the slurry or water is consistent with the direction of the magnetic force line, such as Image 6 As shown, when the pulsation direction of the pulp or water is consistent with the direction of the magnetic force line, the particle group adsorbed on the surface of the medium only exists on the side along the direction of the magnetic force line. Due to the presence of a medium in front or behind the particle group, the buffering effect of the internal liquid slows down the fluid force, which is not conducive to the evacuatio

Embodiment Construction

[0019] A double-frequency pulse double vertical ring high-gradient magnetic separator, comprising a sorting ring 1 and a magnetic field device 2, characterized in that the magnetic field device 2 is distributed on both sides of the sorting ring 1, which can generate magnetic lines of force running through the sorting ring 1, Below the separation ring 1 is provided at least one set of pulse devices that can cause the pulp to move in a direction perpendicular to the magnetic lines of force.

[0020] like figure 1 , figure 2 As shown, the present invention includes a sorting ring 1, a magnetic pole 2, and a double-pulse device 3. The sorting ring 1 is composed of a thick-walled ring, a thin-walled ring, a magnetic medium, and bolts, wherein the ring body 13 is a vertical double-ring structure, and the ring body 13 is a vertical double-ring structure. There is a turntable 12 that connects the double rings as a whole. The outer edge of the turntable is made of magnetically condu...

Abstract

The magnetic separator includes separating ring and magnetic field unit, the magnetic field unit is distributed beside the separating ring to produce magnetic force lines penetrating the separating ring, and the separating ring is provided with at least one pulse device to make ore pulp move in the direction perpendicular to the magnetic force lines. Owing to the combined closed magnetic field unit to produce horizontal magnetic force lines and unique double-pulse device, the particles adsorbed to the surface of the medium exist only in the side in magentic force line direction and the ore pulp reciprocates to produce fluid motion tangent to the particle side and shear and clean the particles, so that the included non-magnetic and weak magnetic adherant particles are washed out resulting in greatly raised separating effect.

Description

technical field [0001] The invention relates to a magnetic separator for ore dressing, in particular to a double-frequency pulse double vertical ring high-gradient magnetic separator. Background technique [0002] The high-gradient magnetic separation theory has brought a qualitative leap to the field of magnetic separation, increasing the types of minerals that can be magnetically separated, and widening the upper and lower limits of particle size. [0003] Early high-gradient magnetic separators are periodic, also known as magnetic filters, and this type of equipment is widely used in occasions with extremely low magnetic content and very fine particle size. [0004] The continuous high gradient magnetic separators that appeared immediately include electromagnetic flat ring strong magnetic high gradient magnetic separators, permanent magnet and electromagnetic double vertical ring high gradient magnetic separators. Electromagnetic flat-ring high-gradient magnetic separato...
