SJSL20 7 Heating Zone Lab Twin Screw Extruder Plastic Granulating Machine
Characteristics of twin screw extruder
The screw arrangement are adopted “toy bricks” principle, which assembly according to different machine L/D, different feeding way, different barrel and screw combination, different screen changing and cutting way, different electrical control mode, etc. it meets the features of material and technological process. Give consideration to the plastic universality commonality and appropriability.
