To determine the extent of grinding obtainable, a 60-minute grinding test was made in the 5-inch-diameter, stainless steel attrition grinder using a leonardite-water feed pulp density of 50 percent solids and a 2.5-to-1 weight ratio of sand to leonardite. The grinding medium used was minus 14- plus 28-mesh Ottawa sand.

The attrition mill is a device for mechanically reducing solid particle size by intense agitation of a slurry of material being milled and coarse milling media. For example, in 10 hours of milling, specific surfaces of 40 and 25 m 2 /g were obtained for alumina and barite, corresponding to 38 and 56 nm equivalent spherical diameter, respectively.

The effect of attrition milling on the solid-state oxidation of aluminum powder is important for the reaction-bonded aluminum oxide process. Attrition milling increased the surface area to 14.4 and 20.2 m 2 /g versus 1.2 m 2 /g for unmilled powder and smeared the Al particles, and the surface was hydrolyzed to form bayerite and boehmite. Upon heating the hydroxides decompose to …
