The machine is mainly composed of a forced feeding mechanism, a screw, a barrel, a filter head, an automatic rubber cutting device, a temperature control system and a transmission device.
The base is an integral welded structure and is machined after annealing.
The motor uses a variable frequency motor. 75kw
Form: With a full hardened gear reducer.
