Abstract: Disclosed is a cage bar for a liquid pressing device, which is delimited by at least one pressing edge in the area of a wearing surface of a hard layer. Said cage bar comprises a spacer that is located in the region of at least one lateral face of a basic member and rises above said lateral face. The spacer (15) is welded onto the lateral face of the cage bar (8), is located at a basic distance (20) from a base (17) of the cage bar (8), which faces away from the wearing surface (11), and extends along the lateral face, no further than to the hard layer (14). The spacer (15) also extends perpendicular to a longitudinal axis of the lateral face, said extension being greater than the extension thereof in the direction of the longitudinal axis of the lateral face (21). The spacer (15) has an increasing thickness (22) perpendicular to the lateral face in a direction extending from the hard layer (14) to the base (17).

Abstract: In an internal mixer, the bearing housings of the bearing arrangements for the journals of the rotors are mounted directly on the end walls of the housing. The gaps which are formed between the rotor and the end wall and between the journal and the end wall are connected to the outside by way of outlets. These outlets bridge the bearing which is encapsulated in the bearing housing.
