Separators Overview
Separators, also known as magnetic separator (magnetic separator), can produce a strong magnetic field is a suction device, it will be mixed with hazardous materials in the guide (Fe) magnetic metal impurities removed to ensure the delivery system broken machine, grinding machine, ball mill and other machinery and equipment safety work, and can effectively prevent a large, long-iron zoned split conveyor belt accident can also remove harmful metallic impurities significantly improve raw taste.
I produced the separator to form their source of magnetic field can be divided into electromagnetic separator, strong magnetic hooks permanent magnetic separator; hanging at installation can be divided into non-contact separator, touch separator; circular shape can be divided according to their , rectangular, vertical cylinder, flat, spherical, roller, trench, etc.; press cooling can be divided into natural cooling, forced air cooling, oil cooling, etc.. The use of different occasions and magnetic structure, the formation of hundreds of specifications. Range ferromagnetic debris was removed from the powder particles (30 mesh -300 mesh) to 50 kg, in addition to iron ratio of up to 95%.
Separators are widely used in metallurgy, mining, coal preparation plant, power plants, ceramics, glass, Magnetic plates cement, building materials, chemicals, food and feed processing industry in the emerging waste disposal industry, also need to recycle waste separator in steel. My company produces a variety of separator in in all major steel companies, metal mining, power plants, light industry, building materials, refractories, foundry and other industries widely used, and play a significant role.

China's weak magnetic tailings closed-circuit grinding process transformation of
technical problems and development direction
How to improve the effect of a weak magnetic beneficiation tailings, how to improve the weak magnetic tailings process, how to improve the weak magnetic beneficiation tailings conditions, has become a serious problem. A weak magnetic tailings closed-circuit grinding transformation must adopt advanced processing equipment, scientific and reasonable mineral analysis, rigorous process and technology, therefore, in the transformation of weak magnetic tailings closed-circuit grinding process, Yu Hui uses the most stringent test conditions.
Weak magnetic tailings granularity is too coarse, monomer dissociation is low. After transformation process oxide ore later, still using the original rod mill with closed-circuit grinding magnetic hooks hydrocyclones, hydrocyclone overflow granularity-0.045mm accounted for about 15%, to a weak magnetic separation into rougher obtain iron grade 64%, about 0.5% sulfur content of magnetite concentrate, and then into a large ball with Sec hydrocyclone system composed of closed-circuit grinding fine grinding; cyclone inflow desulfurization flotation, flotation concentrate as pellets raw materials; rough first pass through the cyclone separator tailings off the mud, the bottom stream into four series of small ball mill and hydrocyclone closed-circuit grinding system consisting of finely ground, overflow to the mine as a stand-loop system. Vertical ring concentrates combined with weak magnetic concentrate fed into six series of large ball mill and hydrocyclone consisting closed-circuit grinding system further after grinding through flotation desulfurization.
About setting coarse tailings cyclone separator off the mud problem by experiments prove that this part of the fine mud iron grade is not very high yield is relatively low, tailing iron direct loss of less than 3%, has little effect on iron recovery, But Outward vertical ring magnetic flotation and subsequent desulfurization, especially for relatively large filter, the test measured filtration efficiency Grate Magnets and primary ore than 30% lower. Therefore, the decision directly tailing.
Weak magnetic tail after regrinding the vertical ring magnetic separator feed size-0.045mm content from 20% to 25% to 45% to 55%, vertical ring slightly higher grade iron ore, but the sulfur content decreased. Vertical ring tailings desulphurization efficiency from the previous 30.41 percent regrind increased to 33.1%, flotation desulfurization rate from 12.55% up to 17.4%. But obviously the final concentrate is still up 0.44% sulfur content, the sulfur content is not acceptable. Therefore, reducing the sulfur content of concentrate processing oxide ore is still an important issue.
Through testing, analysis of weak magnetic tail distribution ratio of sulfur and weakly magnetic particle size, reducing the sulfur content of concentrate processing oxide ore is still an important issue, the weak magnetic tailings closed-circuit grinding transformation process has made some achievements, but still need to configure the transformation of mineral processing equipment and technology in order to reduce the sulfur content of the final concentrate. Achieve such results Henan Hui paid a lot of manpower, material resources, but if the effect of the magnetic beneficiation tailings is still a long way to go to improve the subject tests.
