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.
