With the rise of China s mining enterprises, a large number of mineral processing equipments will also produces. In the production process, it is inevitably to concentrator produces dust, with a great deal of harm to the health and production of operating personnel. Twelve Five is a critical period for China to build mining enterprises binding characteristics and the nature of the mine dust developed a new type of low-carbon environmental protection equipment, building a resource-saving and environment-friendly social context, has become the main topics. The emergence of crusher dust is that the crushing operations in material transport and equipment operation, ambient air will produce large amounts of fine particles, the work environment is not conducive to the normal production. In current production, a common method of inertial dust scrubbers, centrifugal dust, gravity dust dust, ESP. These methods are generally easy to operate, the high degree of mechanization, to further reduce and eliminate opportunities for workers exposed to dust, so as to achieve the purpose of dust and protect the health. Mining refers to the crushing crusher machinery whose content is more than 50% of the total content, the row compound particle size is greater than three millimeters.
It is invented by British Hengan. According to the feeding and nesting size, the crushing operations are often divided into coarse crushing, crushing and crushing medium. The commonly used equipments are impact crusher, compound crusher, single stage hammer crusher, vertical crusher, gyratory crusher, roll crusher machines, double roll crusher, crusher combo, and so on. The crusher is widely used in mining, metallurgy, building materials, road, railway, water conservancy and chemical industry and many other sectors. Common crushing machines are winnowing mill, hammer crusher, impact crusher, roll crusher, crusher compound. Jaw crusher (jaw crusher), having large crushing ratio, uniform particle size, simple structure, reliable operation, easy maintenance, operating costs and economic characteristics. PF-I series impact crusher can process materials side length is 100 to 500 mm, the compressive strength is up to 350 MPa, great crushing ratio, cubic particles advantages of material was broken; PF-II series impact crusher machine, suitable for crushing hard materials, such as cement crusher, with a production capacity of the material advantages of small particle size. In addition, in the course of their work, the operator must be strengthened their own protection. Respiratory protective gear is a good protective equipment, in the the isolated dust while effectively safeguard its own security. Mining industry in the development process, should be reasonably well crusher equipment process dust work better for the benefit of business and society
