ABSTRACT:
Mixing apparatus comprises a container which may be in the form of a hollow cylinder with its axis horizontal. It contains mixing means mounted to rotate within the container about its axis and in addition a pulveriser mounted in the cylindrical wall of the container. Whereas in known mixers of this kind the additional pulveriser comprises so-called knife heads which do not in every case grind down sufficiently rapidly and uniformly the material to be treated, in the mixer now proposed the grinding of the material is improved by the addition of a shearing effect. The pulveriser comprises two concentrically arranged relatively rotatable shearing rings and is in a position to disintegrate even materials which are difficult to treat, such as damp materials, rapidly and at the same time efficiently. Fluid can also be added in the region of the pulveriser without the material being caused to form into lumps.
