ABSTRACT:
A cementation apparatus is provided wherein the reaction surface thereof can be increased without changing the outer dimensions. There is provided at least one inner cylinder which is freely mounted in an outer cylinder and placed one within the other. The inner cylinders are perforated along their outer surfaces and are preferably open at both ends as is the outer cylinder. In the cylinder assembly, all the cylinders as well as the cylinder assembly are rotated. A slurry containing material to be treated as well as the amalgam is fed into the cylinders and on rotating the cylinders, the slurry is picked up by the surface of each of the cylinders so as to provide a reaction area for cementation which is equal to the sum of the surface area of all the internal cylinders and inner surface area of the outer cylinder.
