Daily maintenance guide for double-shaft shredders
Maintenance of double-shaft shredders is the key to ensure their long-term stable operation.
Here are some suggestions on how to maintain double-shaft shredders:
1. Regularly check and replace lubricating oil:
● After the machine runs for the first time for 240 hours, the lubricating oil of the reducer must be replaced and the oil in the original reducer must be completely drained.
● The reducer needs to replace the lubricating oil every 5,000 hours (or it is recommended not to exceed half a year).
● Regularly check whether the lubricating oil level meets the requirements to ensure flexible rotation.

2. Lubrication and maintenance of the main bearing:
● Use the correct type of grease, such as No. 3 lithium-based grease.
● The amount of grease filled is generally 1/2~2/3 of the bearing cavity space.
● When the grease becomes dirty, dry or aged, it should be replaced. Under normal circumstances, the bearing must be re-greased after 3,000 hours of operation.
3. Replacement and maintenance of the knife roller:
● The knife roller is designed to withstand high loads and only needs to be replaced when it breaks. The removal and replacement of the knife roller must be completed by professionals.
4. Keep it clean:
● After work every day, the machine should be cleaned in time to check whether the screws are loose and whether the wearing parts are worn.
● Clean the vent cover and filter regularly to ensure good ventilation.
5. Inspection of the electrical system and knife shaft:
● Regularly inspect and maintain the electrical equipment, knife shaft, etc. of the shredder to ensure the normal operation of the equipment.

6. Inspection before starting the machine:
● Ensure that the main machine is stable before starting the machine and it must not swing back and forth.
● Check whether the connecting bolts at all locations are tightened. If they are loose, tighten the bolts before starting the machine.
7. Safety operating procedures:
● When repairing the equipment, it is necessary to shut down the machine with power off, repair it by one person, and disassemble and assemble the equipment according to the repair instructions (using special tools).
● Before starting, make sure that the transmission part of the equipment is normal, and do not start the shredder under load.
● After starting, if any abnormal sound or situation is found, stop the machine immediately for inspection.
8. Other precautions:
● For shredders with hydraulic systems, the oil tank and the surrounding area of ​​the oil tank should be kept clean, and the oil filter element should be cleaned or replaced regularly.

● Regularly check the connection parts and internal parts of the equipment, such as whether the breaker hammer is broken or worn.
The above are some basic suggestions for the maintenance of double-shaft shredders. Specific maintenance methods may vary depending on the equipment model, manufacturer and use environment. Therefore, in actual operation, it is recommended to refer to the instruction manual of the equipment and perform maintenance in combination with actual conditions. At the same time, regular professional training for operators to improve their operating skills and maintenance awareness is also an important guarantee for ensuring the safe and efficient operation of the equipment.
