Crusher - Wikipedia

In industry, crushers are machines which use a metal surface to break or compress materials into small fractional chunks or denser masses. Throughout most of industrial history, the greater part of crushing and mining part of the process occurred under muscle power as the application of force concentrated in the tip of the miners pick or sledge hammer driven drill bit.In industry, crushers are machines which use a metal surface to break or compress materials into small fractional chunks or denser masses.
