The minimum void ratios of Ottawa sand mixed with crushed silica were reported by Salgado et al. (2000). For Ottawa sand, the mean grain size D 50, corresponding to 50% passing weight of the gradation curve, is 0.39 mm and for the crushed silica, the mean grain size d 50 is 0.023 mm. The grain size ratio D/d is 17.Web

Abstract 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.Web

The ability to operate a mill with smaller-diameter grinding media greatly increases the mill's efficiency and can overall further increase the quality of product through finer grinding. However, smaller Glass beads are more prone to hydraulic packing due to their decrease in mass per bead. ... Ottawa sand, Steel balls, Pebbles, Ceramic balls ...Web

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.Web

Many unusable sands, like some beach sands, may be overrepresented in one size range, so to get the desirable overall gradation, most of the sand must be discarded (or used elsewhere). On the other hand, when the cement is the item to be tested, rounded sand of a narrow size range is used (Ottawa Sand, from Illinois, windblown).Web
