Bauxite Mining | The Australian Aluminium Council

Crushing. A crusher is used to break the ore down to a smaller size suitable for transport. The crusher is made up of a number of components that include a vibrating screen, a jaw crusher and sizers. Fine material drops through the vibrating screen while larger material passes over the screen to the jaw crusher that breaks up the large rocks.
