Abstract

The invention relates to a multi-screw extruder for the continuous treatment and/or processing of a bulk material, especially a product in powder, granular or flake form, comprising several shafts ( 3 ) which are arranged in a ring shape in a cavity ( 1 ) of an extruder housing ( 2 ) and which extend parallel to the axial direction (A) of the extruder. The extruder housing ( 2 ) is provided with axially parallel, concave segments ( 5 a , 6 a) of a circle on the radially inner ( 5 ) and radially outer ( 6 ) surfaces of the cavity ( 1 ). These circle segments act as a guide for the axially parallel shafts ( 3 ) with their processing elements ( 4 ) on the inside ( 5 ) or on the outside ( 6 ) of the shaft ring ( 3 , . . . ). The inventive improvement lies in the radial extension of the axial partial area of the cavity ( 1 ) containing the shafts ( 3 ), which is located in the area of the feed opening ( 9 ), this radial extension ( 10 b) extending along part of the shaft ring ( 3 , . . . ) in the peripheral direction (U) of the same.
