Product Description

ADS Double Stage Cutter Compactor Recycling Pelletizing Line

The ADS 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 ADS 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.

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)

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.


ASE adopts high strength hardened reducer; Due to the compact structure and small center distance, the gearbox cannot be configured larger models of bearings, therefore, it is necessary to ensure that concentrate both coupling of motor drive and gearbox, to reduce effect of additional bending-motion to the bearings, which may affect the bearing using-life.

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.


Because of the super L/D ratio, the single stage extruder in the production line can be used as a double- stage extruder. After the middle double-piston type screen filter, another filter can be added at the end. The double filter standard can improve the quality and performance of the final product particles.


It consists of two sets of Single-Screw extruders , suitable for printing ink heavy, high moisture content, poor fluidity and temperature sensitive, high impurity content materials which requires the double filtration system, multiple exhaust and other higher requirements, and a longer process.

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.


This is the most appropriate process for the need for better melt filtration and higher production. In the first stage,two or more single screw extruders can be designed for the two-stage pelletizing production line, and then they can enter the second-stage extruder at the same time.

None-stop Piston Type Filter

* 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.
* Long screen lifetime, lower screen change frequency: Long filter lifetime owing to large filter areas. 
* Easy to use and none-stop type: easy and quick screen change and do not need to stop the running machine.
* Very low operation cost.

Plate type filter

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.

Self Clean Filter

This model combines our self-developed self-cleaning filter.The new SCF self-cleaning filtration system makes non-stopping recycling extrusion, especially suitable to highly contaminated materials re-pelletizing. SCF filtration system can handle and remove up to 5% contaminates in the melt flowing, can separate the contaminates as: paper, wood, aluminum, unmelted plastic and rubbers etc.

Water Ring Pelletizing System

* Self-adjusting pelletiziin head for the best granulate quolity and long uptime thanks to consistently correct blades oressure. 
* RPM of rotatory blades is automatic based on melt extruding pressure.
* Easy and fast pelletizer blades changeover, without adjustment work saves time.

Under-water pelletizing system

Highly automatic pelletizing system. It is suitable for materials with high MFI and high production capacity requirements. This system includes pelletizer, valve, conveying pipeline, dewatering vibrating screen, silo.

Vibration Dry

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

Plastic Particles

Final output: plastic particles,the plastic pellets can be re-used for producing high quality plastic products once again.


* Final qualified granules store here,the drying shaker together with the horizontal centrifuge can get a good drying result, and less energy consumption.
* Capacity online monitoring & Quantitative weighting system.


* Lower investment cost for a high quality and durable machine;
* Low energy consumption with high production output;
* Overseas installation and training are available;
* Machine warranty with spares in stocking and in-time delivery;
