The impact crusher is one of the common crushing equipment, which is widely used in various ore crushing, highway, railway, cement, chemical, energy, construction and other industries. In actual production, some common failures inevitably occur, such as impact crushing. The failure of the machine to start is a relatively common fault, especially in winter, this phenomenon is more obvious. What should we do if the impact crusher cannot be started?

1. If the impact crusher does not start, it is necessary to check whether the plug at the bottom, the power supply and the power cord are in good contact, and whether the outer skin has broken marks. If not, plug in the power cord, power up and debug.

　　2. If the crusher does not start after being powered on, and the wheel can be turned when it is tapped by an object, it can be determined that the two starting capacitors inside the motor have failed. In this case, it is recommended to replace the startup capacitor before starting and retrying.

　　3. The impact crusher does not rotate when powered on normally, and can only complete the rotation with the help of external force. However, when there is current noise inside the motor, it may be caused by a slight leakage of the starting capacitor. If the current noise is too high to start the motor, it should be caused by a shorted start capacitor. In the absence of an instrument, the capacitor can be removed *, then the capacitor can be charged by inserting two wires into the neutral and live jacks respectively, then the capacitor can be removed and the two wires unplugged to discharge. If there is a discharge spark and a "pop" sound is heard, the capacitor has been charged and can be used. If the spark and noise are weak, it means that the capacity of the capacitor is reduced. You can choose to get a new one or add a small one. If the capacitor is shorted, do not use this method, but replace it with a new capacitor of the same specification.

　　4. The rubber V-belt is prone to loosening after the crusher has been working for a long time. If the maintenance personnel fail to adjust the tightness of the belt in time, the V-belt will loosen and cause slippage, and it will be difficult to start.
