Where the use of outside materials will be large granular materials into the process of small particles, called broken machinery used is called crusher. Any use outside of small particles of materials into the process of powder material, called crushing or grinding, or grinding. It is called the use of mechanical grinding machinery. Will be broken and together referred to as broken grinding mill, referred to by the use of mechanical grinding machin broken. Grinding materials broken the purpose and significance of Broken grinding material is designed to: increase the specific surface area material; Preparation of man-made sand and concrete aggregate; so useful ore dissociation; for processing raw materials to prepare for the next step, or easy to use. With the rapid development of the contemporary socio-economic, all kinds of metals, non-metallic, chemical minerals, as well as cement, building materials, and other materials of social demand and the growing scale of production, the need for ground breaking rapid increase in the volume of the material. Since the 90's, a year after breaking ground all over the world of materials amounted to more than 10 billion tons. Brittle materials production in China has reached more than 1.5 billion, of which about 240 million tons of iron ore, non-ferrous metal ore over 100 million tons, more than 260 million tons of non-metallic minerals, chemicals more than 030 million tons of minerals, some more than 400 million tons of cement, building materials with more than 470 million tons of limestone. The vast majority of these materials to go through the broken grinding, crushing and powder works can be seen in the national economy plays a huge role. In mineral processing industry, Concentrator grinding mill pieces of the production cost of operation, the average total cost of more than 40%, while the production cost of grinding operations, the average total cost of more than 40%, while investment in ground equipment accounted for beneficiation plant a total investment of around 60%. In the cement industry, cement the role of broken mill production costs accounted for about 20%, broken machinery, plant-wide power consumption accounts for about 10% of the total power consumption, while the powder machinery accounted for 60% of power consumption. Grinding process of breaking power consumption, steel consumption and the consumption of raw materials and its great. The concentrator has been only as an example, the broken ground of the power consumption per tonne of ore averaged 16KW.H, concentrator accounted for 40% of the total power consumption around. Steel consumption of an average of 1.5KG / T. This calculation, only broken concentrator mill annual power consumption of up to 1.6 billion KW.H consumption 150,000 tons of steel. Therefore, the area of broken ground saving energy, can have a tremendous social and economic benefits, and its great significance and far-reaching.
