The key to improving the life of the jaw plate: the symmetrical structure design can be adjusted when worn, and the efficiency of block replacement of large machines is doubled; parallel fixation during assembly to prevent wear, spring reinforcement bolts during operation to reduce vibration and prevent loosening, scientifically extend the service life and ensure production efficiency.

The following are the methods to improve the life of the jaw plate of the jaw crusher:

1. Choose a reasonably designed jaw plate

The structural design of the jaw plate has a significant impact on its service life. For small and medium-sized jaw crushers, the jaw plate can be designed as a symmetrical structure up and down. When the lower part is severely worn, its life can be extended by turning it over. For large jaw crushers, the jaw plate can be designed into multiple symmetrical blocks, which is convenient for timely replacement of wear blocks and comprehensively improving the use efficiency.

2. The assembly method of the jaw plate must be correct

When assembling the jaw plate, be sure to firmly fix the jaw plate on the movable jaw and the fixed jaw. Adjust with materials such as copper, lead, and zinc to ensure that the movable and fixed jaw plates remain parallel. This step is crucial to prevent the jaw plate and the movable and fixed jaws from wearing or even breaking due to relative sliding when the jaw crusher is working.

3. Precautions for actual operation

(1) When the mounting bolts of the jaw plate loosen due to vibration, causing the jaw plate to wear, even fall off or break, it is necessary to conduct a specific analysis of the causes of the loosening and falling off during the operation of the crushing plate. It is unscientific to simply tighten the fastening bolts of the jaw plate before starting the machine.

(2) Install springs on the fixing bolts to improve the anti-loosening and vibration reduction capabilities of the jaw plate fixing bolts, extend the service life of the jaw plate, and improve the production efficiency and economic benefits of the crusher.
