Definitions

  • the raw material intake in the hopper requires, for example, a large snail chamber volume, the generation of pushing and pressing forces in the working screw a small. This results in a disproportion of the flow rates between the Zu manufacturedschnecken Scheme and the working screw area in which the pressure is built up. This leads to raw material destruction and raw material reflux in the hopper.

As a result, more raw material can be absorbed, so that a larger contact with the support surface or the support system on the inner surface of the pressure tube for power transmission can act, so that an increase in the holding force is effected and effectively prevents the raw material joins the screw rotation.
