Web26 jan. 2024 · Diskpack extruders can be treated as single screw extruders with zero helix angle and very deep flights. The material is fed in the axial gap between thin disks on the rotating shaft. The melt moves with the disks and before one complete rotation, a channel block closes off the space between the disks. Web22 jul. 2024 · Extrusion throughput is calculated by subtracting the volumetric pressure flow of the system from the system’s volumetric drag flow. Determine the values for variables that are required to calculate extrusion throughput. You’ll need to know the diameter of the extrusion screw, the screw speed as measured in revolutions per minute, the angle ...
