One of the most critical components of a jaw crusher is the jaw plates. These are the surfaces that come into direct contact with the material being crushed. They typically come in two varieties the fixed jaw plate and the movable jaw plate. The fixed jaw plate is stationary and mounted on the frame, while the movable jaw plate moves back and forth, creating a crushing motion. The wear and tear of jaw plates are significant since they constantly encounter abrasive materials. Hence, they are often manufactured from high-grade manganese steel to enhance their durability.
