 When the jaw crusher is working normally, it will generate heat, so the bearing temperature should be checked in time. If there is an abnormal temperature, there could be too much or not enough grease, dirty grease, or damaged bearings. The amount of grease should be checked in time, or the grease and bearings should be replaced. If the outdoor temperature is high, the consumption of the wearing parts of the jaw crusher will become more and more serious, so what are the reasons for the temperature rise of the jaw crusher when it is working?
 
jaw crusher
 
1. Bearing temperature. When the jaw crusher works at high temperature, you should always pay attention to the temperature of the bearing to keep it in a good lubrication state, and pay attention to whether the sound and vibration are abnormal. If it is found to be abnormal, s* and check immediately to find out the cause and confirm whether it is stuck by an unbreakable object or the hammer head and other parts are damaged.
 
2. Temperature of friction parts. During the high-speed operation of the machine, the power consumed by friction is all converted into heat, causing the temperature of the friction parts to rise. When lubricating oil is used for lubrication, the heat is continuously absorbed from the friction surface to be dissipated, or a certain amount of oil is supplied to take away the heat to reduce the temperature of the friction surface.
 
3. The temperature of the movable jaw. The jaw crusher uses the up and down movements of the jaw plate to squeeze and roll the material to achieve crushing. The upper and lower parts of the movable jaw are close to the fixed jaw plate. After crushing the material, the movable jaw leaves the fixed jaw and the product is discharged from the discharge port. It can be seen that the operation intensity of the movable jaw is high, and the temperature of the movable jaw is prone to abnormality. When the temperature rises to a certain limit value, the jaw plate will be damaged. If necessary, certain measures must be taken to solve the abnormal temperature rise of the movable jaw to avoid the Equipment failure causes downtime and reduces production efficiency.
