Abnormal temperature of the jaw crusher may be caused by many factors. Here are some possible reasons:

1. Lack of lubricating oil in the movable jaw: The movable jaw is the main operating component of the crusher. When the movable jaw lacks lubricating oil, the increased friction will cause its temperature to rise abnormally.

2. Bearing problems: If the lubricating oil injected into the bearing is too large or fails, the lubrication work will fail, resulting in excessive bearing friction and abnormal temperature of the movable jaw. In addition, if the bearing part is placed in the tightening bushing of the crusher, and the axial swing of the tightening bushing occurs abnormally, it may also cause collision and friction between the movable jaw and other parts, thereby generating heat.

3. Motor problems: Falling off or wearing out fan blades may cause the motor to heat up. In addition, excessive motor power may result in excessive wind speed, and materials may be blown back during the crushing process, causing the motor to work repeatedly and generate heat. If the motor voltage is too low, it will also increase the load on the motor and cause abnormal heat generation.

4. Temperature and environmental factors: When the outside temperature is too high, the internal operating temperature of the crusher may exceed the specified range, causing the motor to heat abnormally.

5. Equipment overload: When the jaw crusher is overloaded, the heat generated by the equipment will also increase, resulting in abnormal temperature.

6. Cooling system failure: Cooling system failures such as fan failure, blocked heat sinks, damaged heat pipes, etc. may lead to poor heat dissipation of the device, which in turn may cause the body temperature to be too high.

7. Excessive dust accumulation inside the device: Excessive dust accumulation inside the device will not only affect the performance of the device, but may also affect the cooling system, leading to poor heat dissipation.

To solve the problem of abnormal temperature of the jaw crusher, it needs to be investigated according to the specific situation. , check whether the lubrication system is operating normally and ensure that the movable jaw and bearings are properly lubricated. Secondly, check the working status of the motor and cooling system to ensure that they can operate normally and dissipate heat. At the same time, pay attention to the influence of external temperature and environmental factors, and adjust the working conditions of the equipment in a timely manner. If none of the above fixes the problem, you may need to call in a professional for further inspection and repair.
