Abstract
It is provided a charging system for feeding processing material, in particular granular processing material to at least one extruder screw, comprising a hopper that is adapted to guide the processing material along a feed direction to the extruder screw and extends along a hopper axis, which in the properly mounted state of the charging system extends parallel to a longitudinal axis of the extruder screw. In the proposed charging system, the hopper includes a plurality of recesses each extending axially with respect to the hopper axis on a hopper wall extending around the hopper axis.
