Crushing in Mineral Processing
Crushing is the first stage in the comminution process. This is usually a dry operation, which involves breaking down the ore by compressing it against rigid surfaces or by impacting it against hard surfaces in a controlled motion flow.This process step prepares the ore for further size reduction (grinding) or for feeding directly to the classification or concentration separation stages. Tailings are usually not generated in this process step.
Crusher Types and Application
There are many different types of crusher machine are developed for various industrial applications, such as jaw crusher, impact crusher, cone crusher, gyratory crusher, small stone crushing machine etc.
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.
