In industrial production, the double-shaft shredder is a commonly used equipment for the treatment of various solid wastes, such as plastic, rubber, wood, metal and so on. However, as with any mechanical equipment, the two-shaft shredder may encounter various failures during use. This article will explore the common failures of two-shaft shredders and their solutions to help operators and maintenance personnel manage equipment more effectively and ensure production efficiency and equipment life.
1. The cause of motor overheating failure: overload, poor motor heat dissipation or motor itself failure. Solution: Check whether the load is too large, ensure that the motor cooling system works properly, and replace the motor if necessary.
2. Bearing damage failure causes: insufficient lubrication, poor bearing quality or long-term overload operation. The solution: Check and change the lubricating oil regularly, choose high quality bearings, and avoid prolonged overload operation.
3. Blade wear failure cause: use or handle materials with high hardness for a long time. Solution: Check the blade wear regularly and replace the worn blade in time to maintain the shredding efficiency.
4. Material blockage failure causes: feed speed is too fast, material humidity is too high or shredder design is unreasonable. Solution: Adjust the feed speed, ensure the material humidity is moderate, and improve the shredder design if necessary.
5. Excessive noise causes: bearing damage, improper installation of blades or improper fixing of equipment. Solution: Replace the damaged bearing, reinstall the blade, and ensure that the equipment is securely secured.
6. Electrical control system failure Cause: aging electrical components, wiring errors or improper operation. Solution: Check the electrical components regularly to ensure that the wiring is correct and operate according to the operating procedures.
7. Hydraulic system leakage failure cause: seal wear or damage. Solution: Check and replace worn seals to ensure the hydraulic system is properly sealed.
8. Transmission system failure Cause: gear wear, chain slack or bearing damage. The solution: Check the drivetrain regularly, replace worn gears and chains, and damaged bearings.
Summary: The maintenance and troubleshooting of the two-shaft shredder is the key to ensure its normal operation and extend its service life. Through regular inspection, timely replacement of worn parts and following correct operating procedures, failures can be minimized and production efficiency improved. At the same time, for any fault, should be diagnosed in time and take appropriate measures to avoid equipment damage and production interruption.
