During the WPC pelletizing production process, operational errors or other factors can frequently lead to screw jamming or locking, preventing the screw from rotating. Such incidents not only directly disrupt the production workflow but may also cause irreversible damage to critical components—such as the screw and barrel—upon forced startup of the equipment; in severe cases, this can even trigger production safety accidents. Therefore, accurately identifying the type of jamming or locking fault and following standardized procedures for troubleshooting and resolution is a crucial step in ensuring the stable operation of wood pelletizing production. Drawing on practical experience in wood-plastic extrusion and pelletizing, the engineers at Yongte have developed professional troubleshooting solutions tailored to the specific causes of screw jamming.

Through systematic maintenance, the stability of the equipment can be significantly improved, the energy consumption can be reduced (the fluctuation of energy consumption under normal maintenance is less than 5%), and the life of key components can be extended (the normal service life of screw/drum can reach 8000-10000 hours).

As a professional manufacturer specializing in wood-plastic equipment R&D and customization, Yongte has always adhered to the concept of "customer-centric, technology-driven", and is committed to providing personalized and efficient production solutions for global customers. Recently, we successfully secured a customized order for 4 Cavity high speed WPC profile production line for middle east customer, which fully demonstrated our strong technical strength and flexible customization capabilities in the field of waste recycling and reuse equipment.

Yongte Plastic Machinery's wood-plastic board production line has further expanded the economic value space by making efficient use of non-metallic materials of waste circuit boards. Non-metallic materials account for more than 60% of the total amount of waste circuit boards

To reduce WPC granulator screw breakage, it is recommended to control the source: prioritize bimetallic thread blocks with strict heat treatment during purchase; ensure uniform feeding and regular cleaning of foreign matter in raw materials during use; inspect thread block wear and assembly clearance every 100-200 hours of operation.
