In order to ensure the safe and stable production of the twin-screw rubber extruder and extend its service life, the maintenance of the twin-screw extruder must be strengthened. The maintenance methods are as follows:

1. Maintenance during equipment operation

No sundries are allowed in the materials, and hard substances such as metal and sand are strictly prohibited from entering the hopper and barrel. When opening the cover of the extraction chamber, foreign matters should also be prevented from falling into the barrel. The rubber extruder shall maintain sufficient heat preservation time after heating up, and shall not start operation until it is rotated briskly before starting. The screw is only allowed to start at low speed, and the idling time shall not exceed 2min, the speed can be gradually increased.

2. Daily maintenance host

The engine oil and lubricating oil shall be replaced once every 4000h of operation. If the main motor is a DC motor, the carbon brush of the motor shall be checked once a month and recorded. If necessary, the carbon brush shall be replaced. The electric control cabinet shall be purged once a month, and the wear of the screw and barrel shall be checked quarterly and recorded. Check the gears, bearings and oil seals of the gearbox once a year; During long shutdown, the machine shall be treated to prevent corrosion and pollution.

After the twin-screw rubber extruder fails, it should be repaired according to the steps and methods described in the equipment instruction manual.
