Abstract
The invention relates to a belt magnetic separator. Generally, the present dry-type belt magnetic separator is suitable for separating big ferromagnetic ores but is unsuitable for separating iron ores with smaller particle size. The belt magnetic separator comprises a vibration bracket (1), wherein a driving pulley (2) and a driven pulley (3) are respectively arranged at two ends of the vibration bracket; a magnetic roller is arranged in the driven pulley (3); a belt (4) is arranged on the driving pulley and the driven pulley; a set of steel columns (10) is arranged on the belt; a magnetic system (5) is arranged between the driving pulley and the driven pulley; a feeder (6) is arranged above the driving pulley; and a discharging hopper is arranged under the belt. The belt magnetic separator is applied to dry magnetic separation of fine-granularity and low-grade iron ores.
Description
Technical field:
the present invention relates to a kind of belt magnetic separator.
Background technology:
magnetic separation is a technology of utilizing the magnetic contrast between the mineral to carry out sorting, and the development of magnetic separation is the development of belt magnetic separator after all.Generally adopt the wet type permanent magnet drum-belt magnetic separator to carry out sorting for the iron that contains in the thinner mine tailing of some granularities when perhaps iron ore low for head grade and that disseminated grain size is little is recycled at present; Regulate the concentrate grade and the rate of recovery through regulating feed ore concentration; Concentrate need precipitate again, dewater; Cause and produce investment greatly; Technological process is complicated, and sort cost and improve greatly, if but adopt present dry type belt magnetic separator; Because present dry type belt magnetic separator generally is suitable for sorting (10-120mm) the ferromagnetism ores of bulk; For granularity thin (10mm once) if mine tailing in iron or iron ore low for head grade and that disseminated grain size the is little magnetic field intensity that increases belt magnetic separator magnetic system when carrying out sorting merely improve the rate of recovery, certainly will cause concentrate grade to descend, do not reach the requirement of smelting.
Summary of the invention:
the objective of the invention is to the problem of above-mentioned existence belt magnetic separator in to be provided; Has separating effect preferably for the granularity thin (below the 10mm) and the iron ore of iron-holder lower (below 20%); And production technology is simple, invests low.
Above-mentioned purpose realizes through following technical scheme:
belt magnetic separator; Its composition comprises: vibration bracket, the two ends of described vibration bracket are installed the negative pulley wheel that drive pulley and the inside have magnetic drum respectively, on described drive pulley and the described negative pulley wheel belt are installed; Has one group of steel column on the described belt; Magnetic system is installed between described drive pulley and the described negative pulley wheel, and batcher is installed in the top of described drive pulley, and discharge bucket is installed in described belt below.
described belt magnetic separator; Described discharge bucket comprises mine tailing discharge bucket, concentrate discharge bucket, chats discharge bucket; Described mine tailing discharge bucket is installed in the below of negative pulley wheel; Described concentrate discharge bucket is installed in the below of drive pulley, and described chats discharge bucket is installed in the below of magnetic system.
described belt magnetic separator, the line and the angle between the horizontal line in the axle center of described drive pulley and described negative pulley wheel are 0.5-10 °.
Beneficial effect:
1. the present invention is owing to adopt vibration bracket, and belt is vertical tremor in motion, the magnetic system that adopts NS alternately to arrange; Good separation effect; Be specially adapted to fine-grained sorting mineral, mine tailing is along with belt movement is discharged to a side of negative pulley wheel automatically, and concentrate falls into the concentrate discharge bucket automatically run to away from magnetic system with belt after; The present invention is ad hoc chats discharge bucket; Can directly smelt or carry out the secondary sorting according to the grade situation of actual detected, concentrate grade be high, and the rate of recovery is high.Utilize the present invention to carry out dry type magnetic separation, saved the flow process of essence mine dehydration, technological process is simple, and construction investment is little, and production cost is low.
2. the present invention are provided with one group of steel column on belt, because the magnetic conduction effect of steel column helps iron ore to the steel column enrichment, separating effect further improves.
Certain inclination angle is arranged to have with belt and horizontal line in
3. the present invention, in the process that belt vibrations are advanced, helps iron mineral and gangue mineral separates, and is convenient to improve concentrate grade.
Description of drawings:
accompanying drawing 1 is the structural representation of this product.
The specific embodiment:
Embodiment 1:
belt magnetic separator; Its composition comprises: vibration bracket 1; The negative pulley wheel 3 that drive pulley 2 and the inside have magnetic drum is installed at the two ends of described vibration bracket respectively; Belt 4 is installed on described drive pulley and the described negative pulley wheel, is had one group of steel column 10 on the described belt, between described drive pulley and the described negative pulley wheel magnetic being installed is 5; Batcher 6 is installed in the top of described drive pulley, and discharge bucket is installed in described belt below.Magnetic system is positioned at the end near negative pulley wheel, because the negative pulley wheel the inside has magnetic drum, forms continuous magnetic field between magnetic system and the negative pulley wheel and avoids concentrate in the process that falls, directly to fall into the mine tailing bucket.Having a segment distance between magnetic system and the drive pulley is convenient to concentrate and breaks away from from belt.
Embodiment 2:
described belt magnetic separator; Described discharge bucket comprises mine tailing discharge bucket 7, concentrate discharge bucket 9, chats discharge bucket 8; Described mine tailing discharge bucket is installed in the below of negative pulley wheel; Described concentrate discharge bucket is installed in the below of drive pulley, and described chats discharge bucket is installed in the below of magnetic system.
Embodiment 3:
described belt magnetic separator, the line and the angle between the horizontal line in the axle center of described drive pulley and described negative pulley wheel are 0.5-10 °.
The magnetic pole that
described magnetic system adopts one group of N-S utmost point alternately to arrange can adopt electromagnet or permanent magnet.
