How to extend the service life of jaw crusher

1. Precautions for jaw crusher installation

1. Due to the large size and heavy weight of the equipment, the vibration of the equipment is relatively large, so the machine should be installed on a concrete foundation to reduce the impact of equipment vibration during operation. At the same time, hardwood pads, rubber belts or other shock-absorbing materials should be placed between the crusher and the concrete to better fix the equipment and prevent vibration;

2. The discharge trough should be laid with a layer of metal plate and have a sufficient slope to ensure smooth discharge of the finished product and normal and stable operation of the equipment;

3. The size of the discharge port should be adjusted according to the required product particle size and processing capacity. When adjusting the discharge port, the tension spring should be loosened first, and then the spring tension should be adjusted after adjustment to prevent the toggle plate from falling off during operation.

2. Precautions for jaw crusher use

1. When the jaw crusher is just started, do not rush to put materials into the equipment. Wait until the equipment is running normally before putting materials in, so as to ensure the normal use of the equipment;

2. The materials to be crushed should be evenly fed into the crushing chamber. Remember not to add materials sideways or fill the feed port to avoid overload; when the equipment is stopped, you should stop adding materials first and turn off the power after the materials in the crushing chamber are completely removed;

3. When the equipment is operating normally, the bearing temperature rise cannot exceed 30 degrees, and the highest cannot exceed 70 degrees. If it exceeds the specified temperature, it should be stopped and checked in time, and it can be used normally only after the fault is completely eliminated;

4. If the crushing chamber is blocked during the crushing process, the power supply should be turned off to stop the equipment from running, and the materials in the crushing chamber should be cleaned up before starting the equipment for operation;

5. Regularly check whether the vulnerable parts of the equipment are worn. If there are such phenomena, repair and replace them in time. When crushing large pieces of materials, always observe whether there is material squeezed out to avoid endangering the safety of the staff.

3. Maintenance strategy for jaw crusher equipment

1. Before the jaw crusher is started, the condition of each accessory should be checked first to see if the parts are loose and the screws are tightened. If there is any problem, repair it immediately to ensure the stable operation of the jaw crusher.

2. Before the jaw crusher is started, the bearings should be carefully inspected to ensure that the bearings are greased as much as possible. If the bearings are short of oil, they should be oiled immediately. Dry bearings will increase the friction of the equipment bearings, which will accelerate the wear of the bearings and reduce the life of the equipment.

3. When the machine is running, always pay attention to the operation of the machine and pay special attention to the machine instruments. If there is any abnormality, the equipment should be shut down and the operation should be stopped.

4. When the jaw crusher is started, it should be started before feeding. Before shutting down, the material should be drained and the material should not be left in the cavity.
