Industrial use of crusher

In industry, crushers are machines which use a metal surface to break or compress materials. Mining operations use crushers, commonly classified by the degree to which they fragment the starting material, with primary and secondary crushers handling coarse materials, and tertiary and quaternary crushers reducing ore particles to finer gradations. Each crusher is designed to work with a certain maximum size of raw material, and often delivers its output to a screening machine which sorts and directs the product for further processing. Typically, crushing stages are followed by milling stages if the materials need to be further reduced. Crushers are used to reduce particle size enough so that the material can be processed into finer particles in a grinder. A typical circuit at a mine might consist of a crusher followed by a SAG mill followed by a ball mill. In this context, the SAG mill and ball mill are considered grinders rather than crushers.

  
In operation, the raw material (of various sizes) is usually delivered to the primary crusher's hopper by dump trucks, excavators or wheeled front-end loaders. A feeder device such as a conveyor or vibrating grid controls the rate at which this material enters the crusher, and often contains a preliminary screening device which allows smaller material to bypass the crusher itself, thus improving efficiency. Primary crushing reduces the large pieces to a size which can be handled by the downstream machinery.

  
Some crushers are mobile and can crush rocks (as large as 16 inches. In a mobile operation, these crushed rocks are directly combined with concrete and asphalt which are then deposited on to a road surface. This removes the need for hauling over-sized material to a stationary crusher and then back to the road surface.
Crushing machine is widely applied in many industries such as mining, metallurgy, construction, Highway, Railway, water conservancy and chemicals production. The current widely used crushing machinery are jaw crusher, impact crusher, Vertical shaft impact crusher, hammer crusher, roller crusher and combination crusher, etc. Our crushing machines are relatively more efficient and reliable compared to others. Because we enjoy a 30 years' experience in this field. And every year, we use 15% of our profit to do the research and development of new products. Our quality and innovation are both at the top of this industry.
