Single Screw Plastic Granulator for Waste Film & Soft Plastic Recycling Repelletizing

This mature single screw plastic granulator, also commonly named single screw extrusion pelletizer, is the most cost-effective extrusion equipment for conventional waste plastic recycling industry. Designed for low-complexity regranulation of soft plastic scraps, this single screw recycling extruder features simple structure, low energy consumption and easy operation, widely adopted by small and medium-sized plastic recycling factories to process waste plastic film, woven bag leftovers, agricultural film and packaging scraps into uniform recycled plastic pellets.

Matched with crushing and squeezing compaction equipment upstream, this single screw re-pelletizing machine solves feeding difficulty of light and fluffy waste film materials. The compaction feeding inlet prevents material floating, bridging and air wrapping during feeding, ensuring stable continuous feeding for low bulk-density plastic waste. After melting, filtering and extrusion, molten plastic is cut into finished pellets through strand cutting or water-ring cutting structure according to customer selection.

Compared with twin-screw compounding equipment, this single screw extrusion unit focuses on simple physical recycling rather than complex modification blending. Its segmented temperature control barrel and wear-resistant screw structure guarantee stable plasticization, while optional vacuum vent design removes moisture and volatile impurities to improve finished pellet surface quality. Customers can choose single stage structure for small output or two stage single screw extrusion granulation system for high-yield, high-pellet-quality requirements.

We customize hourly output ranging from 100kg/h to 1200kg/h to fit different production scales. The recycled pellets produced can be reused for film blowing, injection molding and plastic extrusion products, realizing circular utilization of waste plastic resources. The whole unit occupies small space, with low maintenance threshold and fewer vulnerable parts, greatly reducing daily operation cost for recycling enterprises.

FAQ – Frequently Asked Questions for Single Screw Plastic Granulator

Q1: What raw materials can this single screw pelletizer process?

A: Our single screw pelletizer, also called single screw plastic granulator, is mainly applicable for PP PE waste film, woven bag scraps, agricultural mulch film, plastic packaging leftovers and nonwoven fabric trimmings. As stable single screw recycling extruder, it realizes efficient regranulation for various soft thermoplastic waste materials.

Q2: What is the difference between single screw and twin screw extrusion granulation equipment?

A: This single screw re-pelletizing machine is designed for simple waste plastic physical recycling, with lower price, simpler operation and lower power consumption. Twin screw units are more suitable for plastic modification, filling blending and high-demanding devolatilization formula production with higher investment cost.

Q3: Can we customize production capacity and cutting mode for this equipment?

A: Yes, we support full customization. We adjust screw diameter, motor power and feeding structure to realize different hourly output, and provide optional strand cutting and water-ring cutting system to match your raw material characteristics and finished pellet demands.

Q4: Is pre-compression treatment necessary before feeding waste film into the extruder?

A: Loose and fluffy waste film needs squeezing compaction to improve feeding stability and avoid unstable extrusion. If materials are already compacted fragments after crushing, direct feeding is available to simplify your pretreatment flow.

Q5: What after-sales service is included after order placement?

A: The machine enjoys 12-month warranty excluding wearing spare parts. We provide lifelong discounted spare parts supply, overseas engineer installation and commissioning, staff operation training and remote online technical troubleshooting to guarantee long-term stable production.
