Single Screw Extruder

Single screw extruder normally used for recycling, direction extrusion as well as the roto-moulding industries. The screw L/D ratio is from 8-38, with different screw designs for different applications.

As the technology upgraded, the new single screw extruder is not only for plasticizing, conveying and extrusion, but with some special design on the screw, it’s also given the function of mixing and dispersions and the screw speed now is up to 150rpm.
