Crushing and Grinding and Related Machines

The process of crushing large particulate material into small particles of materials by external force can be called crushing, and the used machinery can be called jaw crusher. The process of the using external force crushing small particles of materials into the powder material can be called comminuting or grinding, and the used machinery is grinding machinery.
    In the mineral processing industry, the production costs of concentrator and crushing job averagely accounted for more than 40% of the full production costs of grinding jobs, and the grinding equipment investment accounted for more than 40% of the full cost, and the beneficiation plant's total investment accounted for about 60% of the total investment. In the cement industry, cement crushing and grinding cost accounted for about 20% of the production cost, the power consumption of crushing machinery accounts for about 10% of the total power consumption of the whole plant, and the powder mechanical power consumption is about 60% of the total power consumption.
    In today’s economic development, infrastructure or metal, non-metallic, chemical minerals, as well as cement, building materials industry, etc. are inseparable from the support of the various materials. The social demand and production scale of the crushing materials is always growing. According to the relevant statistics, China's annual grinding or crushing materials have reached 100 million tons since after 1990, today, I think it is more than this number. From this point of view, the crushing equipment or grinding equipment plays an important role in the national economy and will have a very broad development prospects in the future.
