Abstract: A device for the manufacture of extruded bodies from a plastic material or a damp pulp, comprising, arranged at an outlet end of a container for the material or the pulp, an output device (18) with a number of output wings (19) driven by a rotatably driven shaft and at an axial distance from the output device a rotatably driven extrusion device (20) with a number of extrusion wings, of which the outer ends during rotation of the extrusion device sweep closely around the inside of a surrounding cylindrical and perforated wall in order to press out to the space surrounding the wall the fed-out material through perforations in the wall. A stationary guide rail arrangement (16) is provided between the output device (18) and the extrusion device (20) and the output device and extrusion device are driven in the same direction of rotation. The output wings (19) have inclined surfaces (30) which, seen in the direction of rotation, form an acute angle (.alpha.

Abstract: An apparatus for mixing powder and liquid together continuously comprises a housing (1) which has a conical surface (16), and a rotor (7) which is journalled for rotation in the housing and which has a conical surface (9). The housing has provided therein a liquid inlet (20) through which liquid is delivered to a gap between the conical housing and rotor surfaces, and a powder inlet (12) through which powder is delivered to the upper surface (8a) of the rotor. As the rotor rotates, a liquid film is formed on the conical housing surface while, at the same time, powder is thrown onto the liquid film with the aid of rotor-carried guide vanes (10). The mixture is worked and pressed out through an outlet (30) by wing-like elements (11) carried by the rotor.

Abstract: A method and apparatus for continuously mixing a liquid and a powder to form a substantially homogenous mixture. The liquid and powder are fed, via separate lines (22,21) to a cavity (7) in a rotating wheel (3,4) and to powder-accommodating spaces (13) respectively in said rotating wheel (3,4) and are thrown therefrom by centrifugal force outwardly towards the periphery of the wheel. The liquid is pressed from the cavity (7) via a gap (8,9) arranged in the wheel in a direction towards the upper side of said wheel and forms a mist curtain as it exits from the gap. The mist curtain captures the powder particles thrown by centrifugal force from the powder-accommodating spaces (13) and is mixed with said particles.
