ABSTRACT:
A method and apparatus is provided for intimately intermixing a first finely divided dry material into a second finely divided dry material to produce a dry blend of the two materials. In a specific application, the method and apparatus provide an improved means for introducing an homogeneously distributing a dry powdered lubricant into a dry powdered material (such as chlorine) which is to be shaped into a molded article. The means for forcibly introducing the powdered additive into the powdered material which is to be molded into a tablet form may comprise a mechanical device such as a screw type conveyer, e.g., an auger or other suitable mechanical means or it may comprise a pneumatic device which propels the powdered additive into the body of the dried, finely divided material to produce a dry blend.
