The impact crusher is mainly used for coarse crushing and second crushing operations. It can be used to break the surface rock of open pit mines, mining ore and limestone. The impact crusher is widely used in the following conditions, such as mineral materials such as clay, iron ore, and gold-copper ore. The counter crusher is widely used in the following conditions, and the application ratio is relatively large. Metal mines: Impact crushers are used in a variety of metal mines such as gold and copper mines, lead-zinc mines, etc. But most of the other is still concentrated in the coal mine. Coal Mine: The coal mine is the largest user of the counter-crushing equipment, accounting for about half of the total coal mines. In China, it is mainly concentrated in the use of new large coal mines. Stone: The crushed stone industry is more suitable for counter-attacking. Especially the mobile crusher is more suitable for stone mining and processing. In the European countries such as the United Kingdom, it adopts the tire-car traction full-mobile crusher. Cement industry: It is common for cement plants to use counter-crushers. This is the easiest place to use the impact crusher. Non-metallic ore: The impact crusher is more suitable for the crushing of heavy clay ore, gypsum mine and other materials. This machine does not have the problem of blocking the feed port and the discharge port. Municipal Engineering: The counter crusher is used in conjunction with construction waste treatment equipment. It can also be used to process urban waste and garbage for resource recycling. Initial crushing of various hard-to-break materials such as glass and used tires. The counter-crushing sand-making machine is a kind of crusher that appeared very early. In the development and application, the structural transformation is continuously improved, so that it can adapt to various mining operations and expand its application range.
