Physical Bauxite Processing: Crushing and Grinding of Bauxite
A crusher does not know what type of material is passing through it. The crusher does however "know" the feed and product sizes, the compressibility, the work index, the level of stickiness, and the abrasion level. With all the application variables defined, the correct type and model of crushing circuit equipment can be properly specified.
