How to prolong the life of jaw plate

By changing the positive suspension of the eccentric shaft device of the traditional compound swing jaw crusher to a negative suspension, the crusher characteristics are improved and the tooth plate life can be extended by 50%.

Changing the thrust plate of the traditional compound swing jaw crusher to an upward inclined type, the movable jaw tooth plate has a downward component in the direction of movement of the crushing stroke, which is conducive to crushing the material and promoting the material to move downward, reducing blockage. This not only improves the wear condition of the tooth plate, but also improves the processing capacity of the crusher.
: Changing the single movable jaw of the compound swing jaw crusher to a double movable jaw makes the longitudinal relative movement between the two movable jaws approximately zero, eliminating the longitudinal relative movement between the tooth plates from the mechanical movement characteristics, and reducing the wear of the tooth plates.
The structural form of the movable jaw can also be changed to extend its life. Changing the flat movable jaw to a curved movable jaw can greatly reduce the excessive crushing of the material caused by the poor discharge of the discharge port and the resulting severe wear of the movable jaw. In order to ensure that the jaw angle is within the maximum allowable range, the ideal shape of the movable jaw tooth surface should be straight on the top and curved on the bottom.
