Two-stage extrusion line
Two-stage extruder series usually first-stage mixing extruder runs at high speed to obtain better mixing and higher output. The second-stage extruder of the two-stage extruder series must be a single-screw extruder with a larger diameter and a low-speed operation. Low screw speed can avoid excessive shearing force, and the internal cooling system of screw can avoid overheating and strong heat exchange ability. The functional separation of the two allows the operator to carry out a more flexible and predictable mixing process and temperature control.
