Abstract
250,581. Jackson, L. Mellersh-, (New Jersey Zinc Co.). April 6, 1926. Resistance furnaces.-Zinc sulphide is improved in colour by heating at 600-800‹ C. with exclusion of air, and superheated steam or other inert gas may be admitted. The heating may be effected in an inclined electrically heated rotary tube 25, Fig. 3, the material being fed in from a hopper 31 through a conveyer 33. The gas is admitted by a jacketed pipe 41, which enters a stationary pipe 38 which dips under the product that has accumulated in a covered receptacle 40. The tube 25 is heated by a resistance 26 the current being supplied at slip-rings 35.
