Another key difference is the speed at which jaw plates move. In a stationary jaw crusher, jaw plates are typically set low enough to let the jaw move at a slow, steady pace. In a jaw crusher with movable jaw plates, on the other hand, jaw plates will move much faster to break up large rocks into smaller pieces quickly.
