A fixed jaw, mounted in a V-shaped alignment, is the stationary breaking surface, while a movable, "swing" jaw exerts force on the feed material by pushing it against the stationary plate. The space at the bottom of the "V"-aligned jaw plates is the output gap that dictates the size of the crushed product from the jaw crusher.

For example, a 32 x 54 sized jaw crusher will measure 32 inches from the movable to stationary jaw (when measured at the top i.e. the opening), and each jaw will have a 54-inch width. If a jaw crusher is rated by jaw plate size, a suitable rating maybe 600 x 400, which indicates a 600 mm by 400 mm jaw plate dimension.

Like the jaw crusher, the cone crusher provides a relatively low cost crushing solution, but there are application drawbacks that may make another crushing solution more appealing. First, cone crushers cannot accept all material sizes. Any material fed to the crusher must be pre-sized for that particular crusher (usually 200mm or less).

This combination is mainly encountered in floor models that can accommodate large sample pieces, such as the BB 300 jaw crusher. The crushing ratio of a jaw crusher results from the maximum achievable final fineness in relation to the maximum feed size. For Retsch jaw crushers, this lies between 26 and 220. A high value reflects the capacity of ...
