The reason why the jaw crusher temperature rises abnormally

The jaw crusher is mainly used for medium-size crushing of various ores and bulk materials, and is widely used in mining, smelting, building materials, roads, railways, water conservancy and chemical industries. The highest compressive strength of the material to be crushed is 320 MPa. So what are the reasons for the temperature rise of the jaw crusher?

 

 

 

 

First, the bearing temperature. When the jaw crusher is working at high temperature, it should always pay attention to the temperature of the bearing to maintain a good lubrication state, and pay attention to whether the sound and vibration are abnormal. If it is found to be abnormal, stop the car and check the cause to see if it is caught by an unbreakable object or if the hammer and other parts are damaged.
 
Second, the friction component temperature. In the high-speed operation of the machine, the power consumed by friction is converted into heat, which causes the temperature of the friction member to rise. When lubricating with lubricating oil, heat is continuously extracted from the friction surface to be dissipated, or a certain amount of oil is supplied to take the tropics away, so that the temperature of the friction surface is lowered.
 
Third, the temperature is moving. The jaw crusher uses the upper and lower repeated movements of the jaws to squeeze the pressing material to achieve pulverization. The upper and lower parts of the moving jaws are close to the fixed jaws. After the material is crushed, the jaws are separated from the fixed jaw and the product is discharged from the discharge opening. It can be seen that the operation intensity of the moving cymbal is large, and the temperature is very likely to be abnormal. When the temperature rises to a certain limit value, the raft is damaged. If necessary, certain measures must be taken to solve the abnormal temperature rise and avoid the cause. Equipment failure causes downtime and reduces production efficiency.
