Toogle plate in jaw crusher, also known as jaw crusher toggle plate, toggle plate and jaw dies are all important jaw crusher parts, Although the toggle plate is simple, it plays a very important role. The jaw crusher toggle plate not only transmits power to support the swinging motion of the lower end of the movable jaw but also serves as a safety device for the jaw crusher. When the crushing chamber encounters difficult-to-crush materials, the toggle plate breaks first, thereby protecting the valuable components of the machine (such as the movable jaw and the body) from damage. In some simple pendulum jaw crushers, the discharge outlet size is adjusted by replacing toggle plates of different lengths.
