Abstract: A method for adapting a pressing force of at least one blade of a granulating machine for granulating material strands, such as plastic material strands. The granulating machine has a force generating means for pushing the at least one blade with the pressing force against a perforated plate of the granulating machine. The method includes the steps of specifying a blade pressing force; determining a hydrodynamic force, such as axial pressure force, which is generated by rotation of the at least one blade and acts on the at least one blade towards the perforated plate; determining the pressing force on the basis of the specified blade pressing force and the determined hydrodynamic force; and providing the determined pressing force to adapt the pressing force prevailing in the granulating machine. Also disclosed are a corresponding computer program product, a controller, a granulating machine, and a method for granulating material strands.

Abstract: A hosing cleaning device for cleaning a housing of a screw machine comprises a support unit displaceable relative to the housing, and at least one housing cleaning unit arranged at the support unit for cleaning an inner wall of the housing, wherein the least one housing cleaning unit can be reversibly inserted into the housing. An associated shaft cleaning device for cleaning at least one treatment element shaft of the screw machine comprises a cleaning chamber, in which the at least one treatment element shaft can be arranged, and at least one shaft unit arranged in the cleaning chamber.

Abstract: A treatment element for treating material by means of a screw machine comprises a conveying section and a melting section. The melting section is arranged downstream of the conveying section in a conveying direction and is connected in one piece with the conveying section. This reduces wear and increases the service life.
