Abstract: A mixer is described having at least one mixing element which rotates relative to a mixing container axis. The mixing element comprises a plurality of vertical rods held by a revolving plate. The velocity and the direction of rotation of the mixing element about the container axis and the rotation of the element about its own axis are such that particles of mix material contacting the mixing element have at all points the same contact velocity.

Abstract: Method and various embodiments of apparatus for producing granulates from pulverulent, granular, doughy or similar material. Material to be granulated is continuously fed into the apparatus and formed into a skin of the material in the nip space between two adjacent and cooperating rotating curved surfaces. The skin and material progresses axially of the rotating surfaces and is periodically and repeatedly kneaded as it is conveyed by the rotating surfaces towards and forced through outlet apertures whereupon it is divided up into granulates. The apparatus can be in various embodiments which use paired, skinforming rotating curved surfaces and can be the surfaces of rollers or of at least one roller cooperating with the internal surface of a drum. The rolling surfaces can be cylindrical or combinations which include one or more cylindrical, tapered or axial contoured surfaces. Single or opposed helical lands or grooves can be incorporated in one or both of the paired rotating surfaces.

Abstract: The present invention relates to a mixer having a substantially vertically arranged rotating container of cylindrical or frustoconical shape, and a rotating mixing screw arranged therein, the said screw having relative movement along the container wall and conveying the mix material upwards.

Abstract: Apparatus and a process for mixing in a continuous manner viscous, gel-like, paste-like, fluid, or other materials by means of a mixing-container which continually revolves and which has mixing elements arranged therein. The mixer revolves at such a speed that the mixing-material will lie along at least one portion of the circumference of the mixing-container. The mixing elements are independently driven screw conveyors or adjustable deflection blades which cause the material within the mixing container to be moved back and forth axially of the rotating mixing container and progressing step-wise from the inlet end to the outlet end of the mixing container.
