When the jaw crusher is working, the movable jaw plate reciprocates with the fixed jaw plate in time. When it is close, the stone is crushed by the influence of squeezing, splitting and impact between the two jaw plates; when leaving, it has been broken. The stones are discharged from the discharge port under the influence of gravity. It can be seen that the fixed jaw plate is one of the easily worn parts of the jaw crusher. So, what can be done to reduce the wear of the fixed jaw plate of the calcite jaw crusher?      1. Choose materials with strong wear resistance. When purchasing jaw crushers or replacing jaw plates, choose jaw plates made of materials with high Mohs hardness, strong toughness and good wear resistance. Practice shows that high The durability of manganese alloy jaws is improved.
     2. Pay attention to the tightness of the jaw plate during installation. There are many constant strengthening during installation. The jaw plate can be a tooth-shaped jaw plate. If necessary, a layer of better plasticity can be placed between the jaw plate and the jaw head. The material keeps the jaw plate firmly on the jaw head, makes the contact between the jaw plates of the jaw crusher smooth, and reduces friction.
