Single Screw Extruder Pelletizing for Plastic recycling

Single Screw Extruder Pelletizing for Plastic recycling

Application of Extrusion & Pelletizing System

According to customers' different production's condition combined with our almost 20 years' experience, we can always find out the best customized solution.

The most two important parts for pelletizing are extrusion system and pelletizing system. For extrusion there are some different kind of concept available. Like Single Stage or Double Stage single screw extruder or co-rotating parallel twin screw extruder. The application is always based on the production's requirement.

According to different material and processing, the pelletizing concept are also to be defined, we have water cooling strips (noddle) cutter method, water circu cooling cutting method, air cool hot cutting method , and others. when we offer you the machine , we will make the proposal according to your materials and your capacity need. the followng is some introduction of the machines.

Strand Pelletizing Process description

In strand pelletizing, polymer is cut into pellets after it has cooled and solidified. The Molten polymer flows into a strand die which looks like a sheet die, and the material exits the die through multiple holes. Each hole shapes the material into polymer strand. The strands will be firstly cooled in water bath or trough, then dried by a de-watering unit or air knife, finally are fed into a strand pelletizer, where they are cut into pellets. This pelletizing concept can also be called as "dry cut" the strand will be pelletized after de-watering.

Feature of the Product

According to the pelletizing process, the pellets are cylindrical form.  By "dry cut" the the flat end surface of the pellet can stick together and cause bridging.
