If it is not used for a long time, the twin-screw granulator should be treated with anti-fouling and anti-corrosion. Check the gears, bearings and oil seals of the gearbox once a year. The electric control cabinet should be purged once a month, and the wear of the barrel and screw should be checked every three months, and records should be kept. If the main motor is a DC motor, check the carbon brushes of the motor once a month, keep records, and replace the carbon brushes if necessary. Every 4,000 hours of operation, the oil and lubricating oil should be changed.


If there is a sudden power failure during the production process, the main drive and heating will stop. When the power supply is restored, all sections of the barrel must be reheated to the specified temperature and kept for a period of time before the twin-screw extruder can be started. This is also emphasized by the twin-screw granulator manufacturer. After 500 hours of use, there will be iron filings in the reduction box. Therefore, when replacing the lubricating oil of the reduction box, the gears should also be cleaned. After 500 hours of use, there will be iron filings in the reduction box.
