Double Stage Cutter Compactor Recycling Pelletizing Line

The series single screw extrusion and pelletizing system is a specialized and reliable system, suitable to the recycling and re-pelletizing job of rigid plastic scrap. It combines function of plasticization and pelletizing to one step and is ideal for crushed regrinds or flakes of PE/PP/ABS/PS/HIPS/PC etc.
Final productions produced by single screw extrusion line are in the form of pellets/ granules, can directly put into the production line for film blowing, pipe extrusion cand plastics injection,etc

Spiral Feeding Machine

Lumps or thick flakes after crushed, conveyed into the single screw extruder by screw loader, then, compress, plasticize in the extruder and removed volatiles and moisture by vacuum system, after filtering through the filtration system, to pelletize into granules. Depending on the different screw diameters of single screw, the typical capacity can cover from 100kg/h to 1000kg/h,Loading motor power: 2.2 kw. Conveying pipe made with stainless steel material, pipe inner thickness is 2mm, pipe diameter is 102mm.

Main feeder (Volumetric)

Main feeder (Volumetric)

It will feed the materials into the extruder. There is a stirring screw to avoid material’s blockage at the bottom of the feeder. Feeding hopper with level indicator.
If  you want to compound the materials, side feeders are optional.

Single Screw Extruder

Single Screw Extruder

Our unique design single screw extruder gently plasticizes and homogenizes the materials. Our bi-metal extruder has great anti-corrosion resistant, wear resistant and long life time.

Double Vacuum Degassing Zones

Double Vacuum Degassing Zones

With double vacuum degassing zones, volatile such as micro-molecules and moisture will be removed efficiency to improve the quality of granules, especially suitable for the heavy printed materials.

Plate type screen changer

Plate type Screen Changer

The Plate type filter is made in a continuous type with two filter plates. There is at least one filter working when the screen is changing.Ring-shaped heater for consistent and stable heating


None-stop Piston Type Filter

None-stop Piston Type Filter

1.A regular single-plate/piston double-station screen changer or non-stop double plate/piston four-station can be installed on head of extruder to present significant filtration performance.
2.Long screen lifetime, lower screen change frequency: Long filter lifetime owing to large filter areas.
3. Easy to use and none-stop type: easy and quick screen change and do not need to stop the running machine.
4.Very low operation cost.

Strap mold

Strap mold

The pull rod mold is widely used, and raw materials such as PP, PE, ABS, PET, etc. can be applied economically and economically

Plastic granulation line cooling   TANK

Plastic granulation line cooling TANK

1.Advanced dewatering vibration sieve combing with horizontal-type centrifugal dewatering present high performance dried pellets and lower energy consumption.
2. Assemble sieves: The sieves are installed and fixed by screws instead of welding, so you can change the sieves easily in the future.
