The treatment unit has a comminuting device and a conveying device which are received in a housing. An outlet opening is arranged in an end region of a conveying section of the conveying device. The plasticizing device has an extruder screw which is received in an extruder housing. The extruder housing is equipped with a filling opening which is arranged so as to directly adjoin the outlet opening arranged in the housing. In the region of the outlet opening, the conveying device has a circulating direction which runs in the opposite direction of the conveying direction of the extruder screw.

Mixing and plasticating machine (100) for continuous conditioning processes, comprising: a housing (10) in which a hollow interior (18) is formed that is delimited by the interior peripheral surface of the housing (10) and extends in the longitudinal direction of the mixing and plasticating machine (100); a screw shaft (12) which extends through the interior (18) of the housing (10), rotates in the interior (18) of the housing (10) during operation and simultaneously moves translationally back and forth; a drive which rotates the screw shaft (12) during operation; and a filling device (36) arranged on the housing (10), for feeding at least one starting material into the interior (18) of the housing (10), the filling device (36) extending through a cut-out (42) that extends through the housing wall (40) or being connected to a cut-out (42) that extends through the housing wall (40), the filling device (36) comprising at least two cavities (54, 54) that each extend over the height of the filling device (36), which cavities are separated from one another by at least one separating wall (52, 52).

A connecting tube assembly (128) for an extruder (110) is proposed. The connecting tube assembly (128) comprises a connecting tube (130), wherein the connecting tube (130) is configured for connecting to a dosing conveyor device (118) and a side feed (126) of the extruder (110), wherein the connecting tube (130) defines a longitudinal axis (132), and a drive device (142), wherein the drive device (142) is configured for rotating the connecting tube (130) about the longitudinal axis (132). Furthermore, an extruder (110) is proposed.

A flow path forming device is provided that includes: a first flow path forming member having a first flow path forming surface; and a second flow path forming member having a second flow path forming surface. The first flow path forming surface and the second flow path forming surface form a flow path through which a plastic composition flows. When a water droplet is deposited on a droplet deposition surface of each of the first flow path forming surface and the second flow path forming surface, and the droplet deposition surface on which the water droplet is deposited is tilted to measure a maximum droplet weight, an average value of the maximum droplet weight on the first flow path forming surface and the maximum droplet weight on the second flow path forming surface is 8 g or more and 25 g or less.

Disclosed is a system for pelletizing Solid Refuse Fuel (SRF).
