A jaw crusher is a sturdy machine that breaks down big rocks and ores into smaller pieces. It has two main parts: a fixed jaw that doesn't move and a swinging jaw that does. They are frequently used in rock quarries or by manufacturers that need to break material down until all the pieces are of equal size.
Pitman is the main component of a jaw crusher that forms the moving part of the crusher. It functions as the link between the stationary and the moving jaw. The pitman is responsible for transferring the motion of the eccentric shaft to the rest of the crusher components, such as the toggle plate and the swing jaw.
A jaw crusher operates by the movement of a movable jaw in relation to a fixed one to crush large rocks into smaller pieces. It does this by using a spinning shaft that makes the movable jaw move back and forth.

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.
Increasing the Gates-Gaudin-Schuhmann and the Rasin-Ramler indexes mean that by increasing the feeding rate on the jaw crusher, the uniformity of particle size distributions of the products increases.
