Flexibility is everything. We offer mobile crushers and screens, both tracked and wheeled, to help you process rock in the toughest conditions. This selection includes jaw crushers, impactors, cone crushers, screens and scalpers for quarrying and rock excavation projects.
A mobile crusher is a machine designed to reduce large rocks into smaller rocks, gravel, or rock dust. The earliest crushers were hand-held stones, where the weight of the stone provided a boost to muscle power, used against a stone anvil.
Mining operations use crushers. Commonly, it is classified by the degree to which they fragment the starting material. There are primary and secondary crushers handling coarse materials, and tertiary and quaternary crushers reducing ore particles to finer gradations.
Each crusher is working with a certain maximum size of raw material. It often delivers its output to a screening machine. Then, the product goes through sorting and directed for further processing.
Dump trucks among others are use to deliver raw materials into the primary crusher’s hopper. A feeder device such as an apron feeder, conveyor or vibrating grid is controlling the rate at which this material enters the crusher. 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 1.5 meter (60 inches). Primarily used in-pit at the mine face these units are able to move with the large infeed machines (mainly shovels) to increase the tonnage produced.
