SJ Series Single Screw Extruder for Plastic Recycling and Pelletizing System
SJ series single screw extrusion and pelletizing system is a specialized and reliable system, suitable to the recycling and re-pelletizing 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 and plastics injection, etc.

The operation of a single screw extruder involves feeding the plastic material into a hopper, which is then transported along a rotating screw within a heated barrel. The screw applies pressure and heat to melt the plastic and force it through a die, which shapes the plastic into the desired product or form.
To use a single screw extruder for recycling squeezed films or rigid flakes, the material first needs to be prepared by cleaning and shredding it into small, uniform pieces. These pieces are then fed into the hopper of the extruder and processed as described above.
Single screw extruders are versatile machines that can be used for a wide range of plastic processing applications, including recycling and extrusion of various plastic materials. They are widely used in the plastics industry due to their efficiency, reliability, and cost-effectiveness.
