Dosing feeder machine for pelletizing system

If your pelletizing material is a hard type, we recommend using the dosing feeder machine for your pelletizing system.

Dosing-feeder for Plastic pelletizing machine

If your pelletizing material is a soft or film type, we recommend using the compacting silo feeding machine for your pelletizing system.

Commonly Used Equipment In Plastic Pelletizing Lines

The following equipment contains the names and applications of the main equipment in the PET recycling washing line, if you want to know more please feel free to contact us!

Screw Feeder
Screw feeder machine for plastic pelletizing line

The screw feeder machine is responsible for delivering a consistent flow of plastic material into the extruder, ensuring uniform processing and melting.

 
Dosing Feeder
Dosing feeder machine for pelletizing system

The dosing feeder machine in a plastic pelletizing line (single-screw) precisely regulates the amount of raw material fed into the extruder, ensuring consistent flow and uniformity in the final product.

Extruder Mainframe
Extruder mainframe for plastic pelletizing line
The extruder mainframe is responsible for melting and feeding plastic material through the screw, applying heat and pressure to form a continuous melt stream for shaping into pellets.
 
Vacuum Exhaust
Vacuum Exhaust Plastic pelletizing machine
The vacuum exhaust system removes trapped air, moisture, and volatile compounds from the melted plastic to ensure better pellet quality and prevent defects.
 
Filter
Filter for plastic pelletizing system
 
The filter‘s role is to remove impurities and contaminants from the molten plastic before it is formed into pellets, ensuring the quality of the final product.
Extruder Submachine
Extruder submachine plastic pelletizing system
 
The extruder submachine melts and homogenizes the plastic material before it is forced through a die to form continuous strands, which are then cut into pellets.
 
Water-Ring Cutter
Water-ring Cutting for plastic pelletizing line
 
In a plastic pelletizing line with a single-screw extruder, the water-ring cutter cools and cuts the extruded plastic strand into uniform pellets by passing it through a water bath before cutting.
Dehydrators & Vibrating Screens
Dehydrators & Vibrating Screens for plastic pelletizing line

 

For removing water from particles and separating similar sized particles under the action of a vibrating screen.

Control Cabinet

A single-screw pelletizing line can process a wide range of thermoplastic materials such as polyethylene (PE), polypropylene (PP), polystyrene (PS), and polyvinyl chloride (PVC), among others.

In a single-screw system, plastic is fed into an extruder, melted by heat and mechanical force, then passed through a die to form a continuous strand. The strand is cooled in a water bath and then cut into uniform pellets by a water-ring cutter.

Single-screw systems are typically simpler, more cost-effective, and easier to maintain compared to twin-screw systems, making them ideal for standard plastic processing with lower production complexity.

Pellet size and quality can be controlled by adjusting parameters like extrusion speed, cooling water temperature, cutter speed, and the extrusion die design.

The production capacity typically ranges from 100 kg/h to 1000 kg/h, depending on the material type, extruder size, and line configuration. However, it can vary based on the specific application and setup.
