Red (brown) iron ore magnetic separator is a special beneficiation equipment for hematite, the magnetic field strength of the equipment is as high as 14500Gs, the magnetic field gradient is large, the power consumption is low, and the performance is stable. This series of equipment is used for the sorting of low-grade weak magnetic hematite, which can improve the grade of hematite by 5-15 at one time, which solves the problem that low-grade hematite can not be smelt in the furnace and is difficult to sell, and finds a way out for low-grade ore, which can produce considerable economic benefits. The equipment has a high return on investment and is a good project with less investment and quick results.
The raw ore of 0.04-5 mm is sent into the upper hopper, and the material output can be precisely adjusted by the hand wheel after the vibration motor vibrates the cloth. The magnetic roller is driven by the speed regulating motor, and the speed of the speed is adjusted by the speed regulating meter, which can control the output and concentrate grade of the magnetic separator. The ore particles are sent to the upper magnetic roller through the conveyor belt for sorting. Because the ore particles of hematite are magnetic, they are immediately adsorbed on the magnetic roller by the strong magnetic field, while the gangue particles (mixed stone, sand) are not magnetic (the magnetism is very weak), and the strong magnetic force of the magnetic roller does not produce suction. With the rotation of the magnetic roller, the ore particles have been absorbed on the magnetic roller. The gangue particles are thrown out in front of the separation plate when the magnetic roller is turned to the front position (the grade of the concentrate can be adjusted by changing the size of the Angle of the separation plate), and the ore particles are automatically dropped into a concentrator bucket when they continue to be brought to the demagnetization area by the magnetic roller. Because the gangue dropped by the upper magnetic roller also contains some ore particles with weaker magnetism, they will enter the lower magnetic roller to continue magnetic separation, and the finished ore particles after magnetic separation enter the beneficiation bucket to collect as finished products, and the gangue thrown out through the tailings port, so that the magnetic separation process is over.
1. Good sorting effect: Because the machine adopts dynamic magnetic system design, the mineral material slides, displacements and rolls on the surface of the drum, the drum does not stick material, which is conducive to material sorting, the primary grade can be increased by 1-4 times, and the selection grade can reach more than 60%. 2. Large processing capacity: Because the company adopts the parcel type open magnetic system, the material is not wrapped, there is no blocking phenomenon, so the processing capacity is large, the processing capacity of a single preliminary separator can reach more than 50 tons of raw ore, and multiple machines can also be used in parallel, which can double the output. 3. Adapt to a wide range of industries: the company's dry magnetic separator, divided into four categories, there are more than 20 varieties and specifications. It can meet the needs of various iron ore, river sand, tailings, steel slag, steel ash, sulfuric acid slag, abrasive, refractory, plate making, rubber, grain and many other industries, and some equipment can also be used in one machine. 4. High production effect: dry selection does not use water, so it is not subject to water source restrictions, continuous production all year round, for water-free areas, seasonal water shortage areas, cold areas, can increase 100-150 working days per year, effectively improve equipment utilization.
