Inspection and cleaning of twin-screw extruders

Keeping the twin-screw extruder clean can produce better products. Keeping it clean can also reduce the failure rate and ensure continuous production. The basic elements of twin-screw extrusion equipment maintenance - inspection and cleaning.

The inner wall of the cooling water pipe attached to the twin-screw extrusion equipment is easy to scale, and the outside is easy to rust and corrode. Careful inspection should be done during maintenance. Excessive scale will block the pipeline, and the cooling effect will not be achieved. If the rust is serious, it is easy to leak water. In daily maintenance, scale removal and anti-corrosion cooling measures must be taken. After a period of production and use, a comprehensive inspection of the twin-screw extruder equipment should be carried out to check the tightness of all screws and make inspection records. Imprison the threaded parts that are easy to loosen, and tighten them immediately to prevent failures during the production operation of the twin-screw extruder.

The basic maintenance is to clean the machine and lubricate the various moving parts of the twin-screw extruder. For example, there will be iron filings or other impurities from the gear grinding in the reduction box, check the wear of the gears and bearings and make a record. When cleaning the gears, replace the gearbox lubricating oil regularly. Check and adjust the motors, control instruments and other pipelines and working parts of the twin-screw extruder. If there is a sudden power failure during production, the main drive and heating stop. When the power supply is restored, each section of the barrel must be reheated to the specified temperature and kept for a period of time before the extruder equipment can be started.
