A fundamental model of an industrial-scale jaw crusher

In a jaw crusher, the material is crushed between two plates: a static plate and a moving plate. Compression is applied by the moving plate, and the material becomes crushed. The size reduction obtained by a jaw crusher is form conditioned crushing due to the nature of the machine. There are two main types of jaw crushers, single toggle and ...
