ABSTRACT:
Apparatus for mixing and granulating a finely divided solid material, preferably including a screening of the final granular product, said apparatus including a mixing drum or cylindrical vessel with closable feed and discharge means, a rotatably driven shaft on the drum axis carrying conveyance means for mixing, stirring and conveying the solid material being treated, and pivotal support means to adjustably tilt the drum such that the drum axis and the rotatable shaft are pivoted within a substantially vertical plane. There is preferably a tubular discharge member at one end of the drum to provide a suitable sieve or screening means at the point where the final granular product is withdrawn from the drum. The apparatus is particularly useful in the mixing and granulation steps required to form a multi-component powdery material into granules which can be directly pressed and shaped into tablets, pellets, pills or the like.
