The toggle mechanism is a vital part of the jaw crusher that helps in the crushing process. It consists of a toggle plate and its associated components. The toggle plate adjusts the distance between the jaw plates, allowing the user to control the size of the output material. When the movable jaw plate moves closer to the fixed jaw plate, the material trapped between them is crushed. The toggle mechanism, therefore, not only enables the crushing action but also helps in achieving a consistent output size.
