Recovery of waste energy in the production of expanded shale aggregate [electronic resource] / V.V. Mirkovich, Mineral Processing Division. Ottawa : Information Canada, 1974. iii, 12 p. : chart Technical bulletin ; TB 184 Cover title. "January 1974." Digitized edition from print [produced by Natural Resources Canada]. Includes bibliographical references. “In view of increasing fuel costs and the need for energy conservation, a typical process for expanding shales to light-weight aggregate was studied. It was decided that, for such a granular material, counterflow, moving-bed heat exchangers should be considered for recovery of heat from the exhaust gases and from the product. The depths of the beds were calculated after the method of Munro and Amundson. An overall heat balance of the process indicates that 36 per cent of the heat presently used can be saved"--Summary, p. i.
