Problems solved by technology

However, when this type of equipment handles higher-grade materials, it cannot take into account the enrichment ratio and metal recovery rate. It only produces concentrate and tailings. Only one of the concentrate grade and metal recovery rate can be guaranteed. If both It is necessary to add another section of operation, increasing investment and operating costs, that is, when high-grade concentrates are obtained, the metal loss in the tailings is relatively large; on the contrary, when the tailings grades are effectively controlled, the quality of the concentrates is difficult to guarantee

Embodiment Construction

[0017] Such as figure 1 , figure 2 , Figure 4 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, and a shaft sleeve 19 with a bearing is arranged in the turntable 12. Arc grooves are arranged around the ring body 13, and magnetic medium stacks 14 are respectively arranged in the arc grooves. The above magnetic medium stacks 14 are as follows: image 3 As shown, it includes a medium bead 15, a magnetic gathering medium 16, a medium spacer 17, and a medium box 18, wherein the magnetic gathering medium 16 and the medium spacer 17 are set as interlayers, and are fixed by the medium bead 15 and loaded with a matching medium box of 18. ...

Abstract

The magnetic dressing machine includes separating ring and magnetic poles and features the double pulse equipment, which is below the separating ring and can output tailing and middling by means of its two ore flow shocking frequencies. The double pulse equipment consists of double pulse mechanism, tailing bin and middling bin and the double pulse mechanism is outside the tailing bin and midding bin and connected to ground via the frame. By means of the liquid power and the magnetic force, minerals with different magnetism are separated effectively. The double-pulse equipment can be used to obtain high-grade mineral concentrate while reducing the grade of tailing and obtaining some middling and is especially for processing several minerals with different magnetism.

Description

technical field [0001] The invention relates to a magnetic separator for ore dressing, in particular to a dual-frequency vertical-loop pulse 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 vertical ring high gradient magnetic separators. Electromagnetic flat-ring high-gradient magnetic separator is easy to cau...
