Abstract
Abstract A conical chamber having its longitudinal axis disposed horizontally has input connections at the center of the larger diameter end of the cone shape. The smaller diameter end of the cone is truncated to define a discharge outlet. The cone is mounted for rotation, and the interior surface of the conical chamber contains lifting vanes of short height which extend longitudinally along the inner surface of the cone and act to mix or tumble material loaded into the chamber from the input connections without applying an undue compacting force to such material. A cooling spray is applied to the exterior surface of the chamber and the cooling fluid is collected by a pan which encloses the bottom region beneath the chamber.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
222 words
A reactor for making compactable material comprising a hollow rotatable conical drum; said conical drum being symmetrically disposed around a longitudinal axis and having a large diameter end and a small diameter end; means for rotatably supporting said conical drum with said longitudinal axis of said conical drum disposed generally horizontally; a first and second input conduit means stationarily mounted relative to the rotation of said conical drum and extending into the large diameter end of said conical drum for depositing a liquid and a solid material, respectively, to be mixed and reacted therein; rotating seal means connected to said large and small diameter ends of said conical drum to permit the interior of said drum to maintain a controlled atmosphere; said small diameter end of said conical drum being tRuncated to define a discharge opening; output means connected to said small diameter end of said conical drum for receiving a mixed product from said conical drum; elongated lifter members, having a small height relative to the diameter of said drum, secured to the interior surface of said conical drum and longitudinally extending for at least a portion of the length of said interior surface and radially spaced from one another around the interior surface of said conical drum; and rotating means connected to said conical drum for rotating said conical drum.
