And the difference between single screw extrusion ina twin-screw extruder with two parallel screw is arranged in the same cylinder. Twin screw extruder has many different forms, the main difference is that the different structure of screw. Screw structure of twin screw extruder extrusion machine should be much plex than a single screw, this is because the screw twin-screw extruder and the direction of rotation, such as mesh level etc.. The design of the extrusion machine three-dimensional design, parameters of extrusion system optimization, system simulation using UG platform, draw the twin-screw extrusion machine assembly and ponents of engineering drawing and BCCH125, complete the design of BCCH125 type double screw extrusion machine.
