Plastic Pelletizer machine– Water Ring Cutting Granulation Equipment for Recycled Plastic Extrusion

This mature plastic recycling pelletizer, widely known as high-efficiency water-ring cutting type granulation equipment, is matched cutting terminal for plastic recycling extrusion line, specially designed for pelletizing sticky, low-melting-point soft plastic materials after twin screw or single screw extrusion. As functional plastic recycling granulator and precision plastic cutting machine, it solves pellet adhesion, wire breakage and uneven particle size problems commonly seen in traditional strand pulling cutting mode, becoming preferred cutting solution for PP/PE film, woven bag scraps and flexible plastic recycling granulation projects.
 
The core working principle of this cutting unit: molten plastic extruded from extruder die head is immediately cut into small particles by high-speed rotating cutter, and the cut pellets are rapidly cooled and dispersed by circulating water ring around the die surface, preventing mutual sticking of hot soft plastic pellets. It perfectly matches upstream squeezing dewatering machine and extruder, processing cleaned agricultural mulch film, greenhouse film, stretch film, express bags, shopping bags and woven bag leftover materials after washing and squeezing treatment.
 
Compared with strand cutting system, this water ring structure occupies smaller layout space, avoids frequent wire break shutdown caused by fluffy film material, and runs more stably for long-time continuous production. We configure cutter material, cutter quantity and rotational speed according to different material viscosity and extrusion output, supporting hourly extrusion capacity from 300kg/h to 3000kg/h. Wear-resistant alloy cutting blades extend service life and reduce replacement frequency, lowering daily operation and maintenance cost for recycling factories.
 
Finished pellets processed by this cutting equipment feature uniform size, smooth surface and low adhesion rate, with good market competitiveness for recycled plastic pellet sales. The whole set includes cutting head, circulating water tank, centrifugal dewatering machine and pellet vibrating screening unit, realizing integrated cutting, cooling, dewatering and finished product screening procedure.

FAQ – Frequently Asked Questions for Water ring cutting system

Q1: What is the core advantage of this water-ring cutting system vs strand cutting system?

A: Our core water-ring plastic pelletizer, also categorized as professional plastic pelletizer machine, general-purpose plastic granulator machine and high-precision plastic cutting machine, adopts face cutting + instant water cooling design. It effectively avoids wire breakage and pellet sticking issues of strand cutting, more suitable for high-viscosity, easily-adhesive soft plastic film extrusion granulation with more stable continuous running performance.

Q2: What kinds of recycled plastics is this plastic pelletizer suitable for?

A: This cutting equipment is mainly applied for recycled PP/PE agricultural film, packaging stretch film, courier bags, plastic shopping bags, woven bag scraps and other flexible plastic waste after washing and squeezing treatment. As matched plastic granulator terminal, this dedicated plastic cutting machine solves granulation difficulty of sticky soft plastics that are hard to process with traditional cutting mode.

Q3: Can we customize cutting speed and cutter configuration for this water-ring cutting plastic pelletizer?

A: Yes, we support full personalized customization for our water-ring granulator. We adjust cutter quantity, blade material, rotating speed and die hole layout according to your extruder hourly output, material melt viscosity and target pellet size requirement. We also make structural upgrade for high-adhesion materials, forming exclusive plastic pelletizer and plastic granulator cutting solution matching your whole extrusion line.

Q4: Why is water ring cooling necessary for soft plastic pelletizing?

A: Hot molten PP/PE plastic pellets have high surface viscosity right after cutting, easy to stick together into agglomerates without rapid cooling. Circulating water ring cools pellets instantly after cutting, separating individual particles quickly to guarantee neat pellet shape and stable finished product quality.

Q5: What complete after-sales service can you obtain after purchasing this plastic cutting machine?

A: The whole cutting unit enjoys 12-month warranty excluding vulnerable cutting blades. We supply lifelong discounted spare parts supply, overseas engineer on-site installation, commissioning and operation training, plus remote online technical troubleshooting, ensuring long-term stable coordinated operation with your extruder and full recycling granulation line.
