1. Decreased production
Reason: Uneven feeding, motor belt slipping or loosening, tool or grinding disc wear, and blockage inside the equipment.
Solution: Maintain uniform and continuous feeding; Check and tighten or ｒｅｐｌａｃｅ the belt; Regularly inspect and ｒｅｐｌａｃｅ vulnerable parts; Stop the machine and clean the blockage.
2. Abnormal vibration and noise
Reason: Uneven equipment foundation or loose fixing bolts; Bearing oil shortage or damage; Dynamic balance imbalance of rotors (such as crushers and stone removal machines); There are hard objects (such as stones, metal) stuck inside.
Solution: Secure the anchor bolts to ensure the equipment is level; Regularly add or ｒｅｐｌａｃｅ lubricating grease, and ｒｅｐｌａｃｅ damaged bearings; Contact the manufacturer for rotor balance calibration; Stop the machine and remove foreign objects.
3. Motor overheating or burning out
Reason: Overload operation; Voltage instability; Blockage of ventilation openings; Motor bearings are damaged; The circuit is aging.
Solution: Operate at rated capacity to avoid overloading; Ensure stable power supply voltage; Clean the motor cooling fan and casing; ｒｅｐｌａｃｅ bearings; Check and ｒｅｐｌａｃｅ aging wires.
4. The temperature rise of the bearing is too high
Reason: Insufficient or excessive lubricating grease, incorrect or deteriorated lubricating grease model; Improper installation or damage of bearings; The belt is too tight.
Solution: Add an appropriate amount and correct model of lubricating grease according to the instructions; Reinstall or ｒｅｐｌａｃｅ bearings; Adjust the belt to the appropriate tightness.
