Technical bulletin ; TB 94 Cover title. "August 1967." Digitized edition from print [produced by Natural Resources Canada]. Includes bibliographical references. “Variations in the operation of a vibrating mill were examined experimentally, and the various factors were related to the surface area of product as determined by the Lea and Nurse air-permeability apparatus. It was found that the product became finer as feed rate was decreased, or as amplitude and frequency were increased. The finest products were obtained when media of fused alumina cylinders, 1/2 by 1/2 inch, were used. These products contained approximately 70 percent minus 10 microns material. Plus-325-mesh particles in various amounts were present in all products"--Abstract, p. i. Includes abstract in French. gccst Minerals gccst Processing gccst Equipment Wyman, R. A. Canada.
