Product Description

Product Description

Two-Stage PP / PS Rigid Plastic Flakes Pelletizing Machine

The Direct Feeding PP PS Flake Pelletizing Production Line is a specialized recycling system engineered for converting washed and crushed polypropylene (PP) and polystyrene (PS) rigid flakes into uniform, high-quality plastic pellets.

This high-capacity two-stage recycling pelletizing production line is purpose-built for large-volume processors converting PP and PS rigid plastic flakes into premium recycled pellets. The system integrates a robust single-screw primary extruder with force-feeder for reliable intake of bulky rigid flakes, followed by a secondary refining extruder for advanced melt conditioning. With output capacities ranging from 500 to 1000 kg/h, this line is the ideal choice for medium to large-scale recycling facilities, washing line downstream integration, and compounders seeking cost-effective recycled feedstock. The line's modular design allows flexible configuration of degassing stages, filtration fineness, and pelletizing method to match specific output quality requirements.

Advantage

Direct Feeding Technology Force/crammer feeder eliminates pre-compaction stage, reducing energy cost by 20-30% compared to traditional compactor-type pelletizers
Two-Stage Extrusion Separate melting and homogenization stages deliver stable melt flow and uniform pellet density
Dual-Zone Vacuum Degassing Effectively removes residual moisture, trapped air, and volatile compounds from washed flakes, preventing bubbles and voids in final pellets
Hydraulic Screen Changer Dual-stage filtration with coarse and fine screens removes paper labels, dirt, and fine contaminants
Water-Ring Pelletizing Die-face water-ring cutting produces dense, spherical pellets with excellent free-flowing properties

Application

Recycling of washed PP/PS bottle flakes from post-consumer collection
Reprocessing of rigid container/crate scrap into reusable raw material
Recovery of injection molding runners, sprues, and post-industrial rigid scrap
Pelletizing of washed PP/PS pipe and profile regrind
Production of recycled PP/PS pellets for injection molding, extrusion, and blow molding
Feedstock preparation for compounding and masterbatch applications
