WebMar 1, 2024 · Since most extruders use square-pitched metering screws, both the pitch and lead equal the diameter, and the helix angle is 17.7°. The helix angle can also be calculated as In metering screws, the flighted section is divided into three zones: feed, transition or compression, and metering. WebParallel screws with the same diameter for the length of the screws: Parallel counterrotating TSEs are typically longer than the conical design, and the screw geometry relies on geometric changes to the flight gaps, the flight count, and changes in pitch to achieve the desired processing conditions.
