There are two types of jaw plates: movable jaw plates and fixed jaw plates. The force and wear mechanisms of these two different jaw plates are different. Normally, the impact force received by the movable jaw plate is bigger, so we need to consider the toughness of the movable jaws when purchasing. While the fixed jaw is supported by the frame, the hardness of the jaw needs to be taken into consideration.

Fixed jaw plates are the most important part of your jaw crusher, and they are made from high manganese steel. They attach to the frame of your machine and act as a support for all of its components. If you have an older model, it may be possible to find replacement parts for your machine at an authorized service center or parts dealer.

Since the jaw crusher is used to crush a lot of materials and its application scale is also wide, the raw materials of the jaw plate should be different for different materials to be crushed. If the hardness of the crushed material is high, the hardness of the corresponding jaw plate should also be high; On the contrary, if the hardness of the material is low, the hardness of the jaw plate can be common.
When choosing the raw materials for the jaw plate, in addition to thinking about the hardness and toughness, it’s still necessary to consider the price and try to buy the jaw plates with high quality and low price.

You can also purchase individual pieces if needed; however, these will typically only be available through select dealers with specialized expertise in this area (Sandrock Mining).
