Mine tailings discharge of dry sense of ore into the concentrator via crushing, grinding and sorting, after homework, useful minerals in the ore sorted into one or more of the concentrate product. Places pulp tailings discharged in the state. Fine mineral was smaller, non-ferrous metals concentrator fine mineral rate is generally only 10-20%; a large number of planetary ball mill tailings yield is generally 80% to 90%; even bigger. If a daily processing of 100t small concentrator, tailings daily emissions of up to 80 ~ 90t or more; high-grade ore, fine mineral rate, the tailings is low. If not properly handle a large number of tailings, great harm. Concentrator tailings discharged water often contains a lot of chemical and hazardous substances. Its source is added during beneficiation and ore flotation reagents metal element ball mill, a common lower cyanide, xanthate, black medicine, pine oil, copper ion, lead ion, zinc ion, individual cases may also be arsenic phenol mercury. Tailings water can not reach these harmful substances emission standards, the human body, animals, fish and farmland are harmful. In the current level of technology, some precious metals, rare metals can not be recycled, but with the increase of science and technology, tailings useful components can be re-exploited. Tailings comprehensive utilization of resources at home and abroad have been many instances, such as copper, Hubei Province recorded Mine Tailings rich in gold, silver, copper, iron and other useful components, in recent years, with the development of mineral processing technology in 1985, the Mine use of weak magnetic - intensity magnetic separation technology for Tailings, the recovery of tens of thousands each year t of iron ore from the tailings, the number value for the yuan, is now being further regrinding tailings re-election, so that tailings Gold, silver, copper, iron and other useful minerals to be fully recycled, so much economic progress in mine. Shenyang North Mine Zhongcheng Machine Equipment Co., Ltd. to provide you with the most professional service! Main products: ball mill, flotation machine, mining equipment, processing equipment, gold mining equipment, tailings discharge device dry! Fault Analysis sieve mill small part of the domestic high-yield, high fine, screening grinding sieving device in the presence of screening plate aperture large, small size sieve through material easily cause loose material to run rough, grate plate grate sew easy to plug weaknesses. Causing the user in the course of production increased much, and the quality is volatile, and sometimes even to stop the machine to handle and clean sieve grate grate plate joints, causing great losses to the user. Such a division of labor positions grinding crushing and two positions more clearly and substantially eliminate the phenomenon of over-grinding mill dry ball mill to improve production efficiency of the mill; the structure of the lining of the mill, ball forging graded conduct optimal adjustment, so that each device can maximize system capacity; the ventilation capacity strengthening ball mill liners, through feed area increases, grinding high humidity, high temperature material production decline significantly high yield at the end of the ordinary units, high Fine, screening mill. The use of solid volume lamination theory and principle and according to the nature of broken material, size of the jaw crusher to optimize the design. The new jaw from the material into the crushing chamber to receive continuous extrusion, and in the lower crushing chamber by squeezing a certain distance parallel. Because of the number of materials in the crushing cavity being squeezed times the normal crusher, so crushing efficiency greatly improved.
