A double roll crusher, also known as a roll crusher, is widely used in industrial applications such as sand production, mineral processing, cement, metallurgy, chemical industry, and construction materials. It is especially suitable for crushing medium-hardness ores and rocks, including coal and coal gangue in large coal mines or coal preparation plants. The equipment can be categorized into coarse crushers and fine crushers, depending on the application. These crushers are commonly used in mining and construction industries to achieve efficient ore crushing through high-speed impact.
During the operation of the crusher, many users may encounter issues that affect normal production. Zhongtai Machinery has shared its experience in repairing electrical and mechanical components, including motor maintenance and troubleshooting, to help customers resolve problems effectively.
Here are some steps to troubleshoot a faulty motor:
1. Check if the three-phase power supply is functioning properly.
2. If the power is normal, inspect the fuses, switches, and starters for any faults.
3. If these components are working correctly, remove the belt or coupling and run the motor under no load to determine whether the issue is caused by the load or the motor itself.
4. If the problem lies within the motor, open the junction box and check for scorch marks or other wiring issues.
5. If the junction box appears normal, inspect the bearings for damage or dry grease.
6. If all previous parts are in good condition, check the stator windings for any short circuits, cracks, or grounding issues.
7. Examine the cage rotor for cracks and the winding rotor for broken circuits.
8. Finally, check the brushes and slip rings of the wound-rotor motor.
By following these steps, you can identify and resolve common motor-related issues in your double roll crusher.
