Long time, because the technology is limited, the level of awareness is not high, backward management and extensive development of the comprehensive utilization of mineral resources in China is very low, associated minerals and non-metallic minerals and other useful addition to the goal of mine are mostly discharged into the tailings of the in. This phenomenon is very common in the mines and crushing industry. This development is not fully the negative impact of not only reduces the production efficiency and damage the interests of investors and caused environmental pollution to a certain extent, can be said to be detrimental rather than beneficial. It is noteworthy that in the case of accelerating China's industrialization and urbanization, the contradiction between supply and demand of mineral resources has also increased, mineral resources, especially stone supply shortage situation in many places even have to rely on imports. Therefore, to cherish and take full advantage of the Tailings this valuable wealth has become particularly important, comprehensive recycling of tailings not only significant savings in the primary ore consumption, to increase resources to effectively supply the same amount in the mining case, also to devote the land to reduce environmental pollution and ecological destruction, can be described as killing two birds with one stone, for the benefit of the feat of the community.

To strengthen the tailings recycling, it is necessary to innovate on the device, which requires the mining machinery industry to actively engage in technological innovation. Mine is the energy guzzler, and more and more waste materials and derelict, and therefore must be studied at the same time to ensure safe and reliable production of new technology and new equipment in order to achieve the purpose of energy efficient recycling. Tailings recovery equipment with the mining machinery industry in technical innovation, the endless variety of tailings broken machinery. , Shanghai Kefid Machinery Equipment Co., Ltd. for the tailings recovery processing to develop new and efficient crusher, mill, etc., such as spring cone crusher of HCS efficient spring cone crusher, the HPC hydraulic cone break, 5X and VSI series of highly efficient vertical shaft Impact Crusher, PCL vertical shaft impact break, vertical milling machine and hanging roller mill, trapezium mill equipment. Produced outstanding advantages of the tailings recovery equipment is: tailings recycling capacity, high recovery, low energy consumption.

The cone crusher cavity optimization of design and laminated crushing principle, combining reasonable speed and stroke makes the models acting in the same dynamic cone diameter up to. Therefore, compared with the same type of cone crusher, with higher performance and capacity. The impact crusher set of crushing, shaping and sand three breakup mode in one of the core equipment for the tailings recycling equipment. Vertical mill the powder, the roller device, disc device, compression device, reducer, motor, shell and other components, can be treated tailings further into a variety of industrial raw materials. The separator is an efficient, energy-efficient separator device, used to all types of finished materials separation, are classified. Roller is used to roller compacted crushed parts of the material, disc fixed to the output shaft of the reducer, roll grinding roller compacted material. The pressure device is a grinding roller grinding pressure of the components, to provide enough pressure to crush material to the grinding rollers. Trapezium mill and hanging roller mill equipment package is the main host, separator, blower, jaw broken, bucket hoist, electromagnetic vibrating feeder, storage silos, bag filter, cyclone powder collector. cabinet, motor and other components. These range, crushing or grinding specifications diverse equipment to ensure that the "turning waste into treasure" this application to become a reality.

Shanghai Kefid Machinery Machine Co., Ltd. is an independent research and development, production, sales as one operating jaw crusher, impact crusher, cone crusher, mobile crusher station, impact crusher, sand washing machine, Raymond mill, hanging roller mill, T-shaped grinding, the European version of the mill, vertical mill, micro mill, vibrating screen, vibrating feeder, etc. Mine crushing plant, screening equipment, sand making equipment, and industrial milling equipment, specialized international companies . Provide screening equipment to meet different production line of the sand and gravel sand for stone production line. The production of the crushing and screening equipment and various types mill of similar products in the domestic leading and reached the international advanced level.
