In order to ensure the safe and stable production of single screw plastic granulators and prolong their service life, it is necessary to strengthen the maintenance of single screw plastic granulators, the content of which is as follows.

1. impurities are not allowed in the material, and prevent metal and sand and other hard substances from entering the hopper and barrel.

2. preheating warming time to be sufficient, generally reach the process set temperature should be the constant temperature for fifteen minutes, before driving, manual disk pulley should be light and fast.

3. the screw is only allowed to start at low speed, the idling time should not exceed two minutes, and the feeder can only gradually increase the speed after feeding in a starvation way.

4. 500 hours of operation of the new reducer, need to replace the new oil, the future use of oil quality should be regularly checked, for mixed with impurities or aging deterioration of the oil, must be replaced at any time, while often checking the oil level height, the oil level is lower than the specified height, need to be timely replenishment, from the second time, the reducer every 3000 hours of operation, change oil times.

5. screw lifting mechanism screw in the factory has been filled with low-temperature grease, after once a week wipe, and grease.

6. When the main motor is a DC motor, the motor brush should be checked once a month, make a record, and replace the carbon brush when necessary.

7. The electric control cabinet should be purged once a month.

8. quarterly checks the screw, and barrel wear, and makes a record.

9. once a year check the gears, bearings and oil seals of the gearbox.

10. daily inspection should be carried out, including the lubrication of each lubrication part, the temperature rise and noise of each rotating part of the bearing, the vibration of the unit, the current and voltage display of the motor and electric heater, the temperature of the lubrication and cooling water, the quality of the extruded products, etc.

11. When the machine is shut down for a long time, there should be anti-rust and anti-fouling measures.
