An apparatus for filling a screw ( 7 ) bearingly supported within a housing ( 6 ), in particular of an extruder, for processing of pre-comminuted synthetic plastics material, in particular PET, has a filling opening ( 5 ) for the screw housing ( 6 ). This filling opening ( 5 ) is in flow connection with the lower outflow opening ( 4 ) of an upright receptacle 81 ) for the material to be processed. Within the receptacle ( 1 ), tools ( 30, 31 ) circulate around a preferably vertical axis, and they act on the material positioned within the receptacle ( 1 ). This material is introduced into the evacuable receptacle ( 1 ) through a sluice ( 60 ). A quickly circulating tool ( 30 ) for creating a mixing cone ( 71 ) is disposed between an upper interior portion ( 68 ) and a lower interior portion ( 69 ) of the receptacle ( 1 ). Within the lower interior portion ( 69 ) that constitutes a dwell space for the heated plastics material that has reached it for thermal homogenization thereof, also circulating tools ( 31 ) are disposed, which, however, are mere mixing tools without substantial introduction of power, so that within this dwell space an agglomeration of the plastics material is avoided.
