Jaw Crusher Explained
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.
