Difference between revisions of "Crushers"

In the 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 Stage Crushers| primary]] and [[Secondary Stage Crushers| secondary]] crushers handling coarse materials, and [[Tertiary Stage Crushers |tertiary]] and [[Quaternary Crushers|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 [[Screeners|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 [[Grinders|grinder]]. A typical circuit at a mine might consist of a crusher followed by a grinder SAG mill followed by a grinder [[Ball mills|Ball mill]]. In this context, the SAG mill and [[Ball mills|Ball mill]] are considered [[Grinders]] rather than crushers.
