MAGNETIC SEPARATING the inside belt and sorting tank. The magnetic minerals attached on the surface of sorting tank cannot fall off automatically (cannot unload mine automatically). As the accumulation grows, the separation effect is affected. What’s worse, rapid wear of sorting tank body as well as the belt will be caused, and the normal operation of production will be seriously af- fected. With the magnetic wrap angle of 360° , the magnetic system adopts Nd-Fe-B magnets with high magnetic energy product and high coercivity, strong magnetic density and high affect depth. The demagnetization rate of the magnetic density within 8 years is no more than 5%; Covering the magnetic system with non-magnetic stainless steel to ensure no peeling off of the magnet The sorting tank can be lined with super wear-resistant rubber produced by our company to significantly improve the service life. Under the condition that the grade of the dry tailings is equal to or even lower than that of conventional magnetic roller or conventional dry separator , for rich magnetite of different nature, by adjusting corresponding technical parameters and structure, about 10% tailings discharging and about 1.0%-4.5% of concentration grade can be increased compared to con- ventional magnetic roller or conventional dry separator. Under the condition that the particle size is below 2mm through fine crushing with coarse dissemination size, qualified concentrate with the grade of over 60% can be directly gained. Under the condition that the grade of the dry tailings is equal to or even lower than that of conventional magnetic roller or conventional dry separator , for rich magnetite of different nature, by adjusting corresponding technical parameters and structure, about 30% tailings discharging and about 2.6%-8.7% of concentration grade can be increased compared to con- ventional magnetic roller or conventional dry separator. The concentrate grade of dry separation is significantly enhanced compared to the feeding grade. Discarding a large number of qualified dry tailings can reduce the costs of transportation, stockpiling, ore grinding and min- eral separation, and greatly reduce the concentration ratio and the production costs. It can also reduce the transportation volume of the wet tailings, and prolong the service time of the tailing pond, which is not only beneficial to the production management of the mineral processing plant and reduction of the production costs, but also conforms to the national poli- cies on energy conservation and emission reduction. In the actual production, by using this patented product, more qualified dry tailings increased by 10~30% can be discharged compared to the conventional magnetic roller or conventional dry separator. If one patented product can process 1 million tons of raw ore every year (150t/h, 1million t/a), it can discharge an extra 0.1-0.3million tons of the qualified dry tailings, and reduce 0.1~0.3 million tons of waste rocks before ore grinding every year. If the production costs such as the ore grind- ing, magnetic separation and the wet separation tailing processing is 30 yuan/ton, one set of the patented product can save the production costs of about 3-9 million yuan. Under the condition of the same amount of mining, the output of the iron concentrate basically remains unchanged. As the amount of the waste rocks into the mill is reduced, the annual capacity of the ball mill is actually increased by (100,000-300,000 t/a) for each rapid magnetic turn roller with high and strong magnetic force, and the iron powder produc- tion is correspondingly increased without any investment in plant expansion, increase of grinding and mineral processing equipment, roads, water supply, tailing processing, etc., and with almost no increase of electricity load and labors, the eco- nomic and resource environmental benefits are significant. 团 集 海 鑫 Technical Parameters Spec. & Model CTXG-0606 CTXG-0812 CTXG-0818 Diameter of Cylinder (mm) 600 800 800 Length of Cylinder (mm) 600 1200 1800 Surface Magnetic Density (mt) 300~500 300~500 300~500 Feed Size (mm) -30 -30 -30 Feed Moisture Content ≤ 5% ≤ 5% ≤ 5% Capacity (t/h) ≤ 35 ≤ 100 ≤ 150 Motor Power (kw) 2.2×2 11×2 11×2 Total Weight (t) 2.9 5.8 7.9 Overall Dimensions (mm) (L×W×H) 2700×1700×1900 3400×2000×2100 4200×2000×2100 - 61 -
