This conveyor belt steadily transports loose soft flexible pe pp into the compactor at a continuous and uniform feeding speed, which is critical for stable downstream processing. It is interlocked with the compacting force feeder, once the current rises higher than set, it will automatically stop feeding, when the current drops, the conveyor resumes feeding, which ensure stable material flow and protecting the main motor of granulator from damage.

This unit scans the incoming material for ferrous and non-ferrous metal contaminants before they enter the main extruder. Detection sensitivity: ≥8mm for ferrous metal, ≥10mm for non-ferrous metal. It will automatically alarm and stop the machine when metal is detected, after workers take out the metal then restart it again, which protects the expensive downstream equipment from damage.

This machine uses high-speed rotating blades to cut and densify bulky flexible film into compact, free-flowing agglomerates. It forces this densified material directly into the extruder hopper, eliminating bridging and surging issues. The compacting action also preheats and partially dries the film, boosting extruder throughput and energy efficiency.

This high-torque extruder melts and plasticizes the material under controlled high temperatures, using a suitable L/D ratio for thorough mixing and homogenization. Its robust design handles soft agglomerates, delivering a consistent molten stream. Efficient heat transfer and screw geometry reduce energy consumption while maximizing the output of pelletizer.

This system with a strong vacuum to extract the moisture, trapped air, and volatile organic compounds from the molten polymer. Removing these gases prevents voids, bubbles, and surface defects in the final pellets. It significantly improves pellet density and mechanical properties, especially when processing recycled or wet plastic.

This unit uses hydraulic pressure to shift a slide piston containing filter screens, allowing continuous filtration without stopping the extruder. It filter coarse impurities, gels, and unconverted particles from the primary melt. Quick screen changes minimize production interruptions and maintain stable melt pressure, and minimal leakage, making it ideal for high-volume, long-running operations. Both plate-type and piston-type filters are optional

Mounted at the end of the first extruder, this die head expands the melt to release residual air and moisture before it enters the second extruder. Its specially designed flow channel creates a thin melt layer, maximizing surface area for volatile escape. This step further enhances degassing, good pellet quality and reducing void formation.

This shorter L/D extruder takes the pre-plasticized melt and subjects it to additional mixing and high-temperature plasticize. It refines the melt homogeneity and pushes it through fine filtration for superior pellet clarity and strength. It is optimized for boosting melt pressure and ensuring a stable output to the die face cutter.

This filtration stage uses finer mesh screens to remove micron sized impurities, ensuring the melt is ultra-clean before pelletizing. The hydraulic mechanism enables rapid screen replacement under full operating pressure, avoiding line shutdowns. It guarantees consistent pellet quality and protects the cutting die from abrasive wear. Both plate-type and piston-type filters are available as options.

This system rotates high speed blades directly against the extruder die face to cut the molten strands into uniform cylindrical pellets instantly. The hot-cut method produces pellets with clean, smooth edges and consistent size. Its quick-start design and easy blade adjustment minimize the material waste during the cutting process.

This tank immediately quenches the cut hot pellets in circulating cold water, rapidly solidifying their shape and preventing sticking. The flow design ensures efficient heat exchange, cooling pellets evenly throughout. Proper cooling also locks in material properties and prepares pellets for subsequent dewatering.

This high-speed centrifugal unit with a vertical rotor and screen mesh spins off surface water from cooled pellets, reducing moisture content to below 1%. Its vertical design saves floor space and achieves high dewatering efficiency with low energy consumption.

This vibrating screen separates oversized, undersized, or misshapen pellets from the acceptable product stream. It uses multiple mesh holes to classify pellets into precise size fractions, ensuring only uniform, well-formed pellets proceed. This step enhances the final product’s market value by delivering consistent appearance and flowability.

This system uses a blower to pneumatically  blow qualified pellets into a storage silo, providing automated transport with minimal manual handling. It prevents pellet contamination and damage during transfer, while the silo offers buffer capacity for packaging or downstream use. The enclosed, automated transport reduces manual handling, keeps pellets clean, and facilitates easy bagging or container loading.

This centralized cabinet houses all PLC, inverters, and relays to monitor and coordinate every single machine in the plastic pelletizing line. It provides real-time parameter adjustments, fault diagnostics, and emergency stop functions from a single interface. Its integrated automation ensures stable operation, reduces operator error, and improves overall production efficiency.

We suggest the heat exchanger by side of the water cooling tank, it transfers thermal energy between fluids through a separating wall without direct mixing. Widely used in plastic pelletizing line water cooling, its closed-loop design minimizes contamination, scaling, and corrosion, thereby extending equipment service life.
