Jaw Crusher Jaw Plate Design and Materials Directly Affect the Damage Rate
The main part of the jaw crusher is the jaw plate. The design and materials of the jaw plate directly affect the quality and efficiency of the jaw crusher. The dynamic and static jaw plates are the main worn parts of the jaw crusher, and the quality of the jaw plate is improved. It means that the quality of the jaw crusher has improved.
If you want to choose a high-quality jaw crusher, you must know the following:
1.The influence of the design on the jaw plate: a reasonable design of the jaw plate can reduce the loss of the jaw crusher. Add a lining plate on the jaw plate and replace the jaw plate with the impact contact with the material to avoid the direct contact between the jaw plate and the material for production wear. The low price of the lining plate is easy to replace and can protect the jaw plate. The uneven design can increase the crushing capacity of the jaw crusher, and the angle between the jaw plates can be adjusted according to the different materials and the different particle sizes of the required products.
2.The influence of materials on the jaw plate: The quality of the jaw plate affects its performance. The materials used for a good jaw plate are cast iron and manganese steel alloy. Cast iron has greater hardness and low price, and its disadvantage is poor toughness. Some are prone to fracture, while manganese steel has high toughness, but the price is high and it is not suitable for direct use as the material of the jaw plate. Cast iron and manganese steel are fused in a certain proportion so that the alloy has high hardness and high toughness at the same time. It can be used as a good material for the jaw plate of the jaw crusher.
Jaw plate application note:
1.When assembling the jaw crusher, the crushing plate should be firmly attached to the jaw plate, and the gap between the two should be flat. Soft metal should be used as a gasket between the crushing plate and the jaw plate, and fastened with bolts. When the jaw crusher is working, the broken The board should not be loose, otherwise it is easy to break or wear the broken board and reduce the life of the broken board.
2.In the actual production process, the crushing plate is in contact with the material. The crushing force is very large, especially when crushing materials with high hardness. The bolts on which the crushing plate is installed vibrate and the nuts are loose, which intensifies the wear of the crushing plate and generates loud noises In severe cases, the crushing plate falls off or breaks, causing the jaw crusher to stop and affect production. The spring can be used to make the bolt anti-loosening and self-tightening device. This device is composed of inner spring gland, spring, and outer spring gland. This device is worn on the bolt.
When the nut is tightened, since the spring is compressed to a certain extent by the nut. It produces a strong anti-vibration effect. The bolt loosening force generated by the large crushing force is automatically compensated by the tension force of the spring. So the bolt will not loosen, thus prolonging the crushing time. The life cycle of the board is also improved.
