Attrition Grinding Mill Design
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.
