3) Bulk Density. Bulk Density represents the mass to volume ratio of a bulk sample, including the space between individual particles, and is reported as lbs/ft 3 or kg/m 3. Bulk density is measured by weighing a container of known volume filled with a fertilizer sample.
Steel shot is one of the least expensive grinding medias with the benefit of high density and the availability of a wide range of sizes for small media. The more narrow size ranges of shot will last longer. Density: gm/cc. Bulk Density: kg/l; #/l; kg/gal; 38 #/gal. Color: Black Polishes to Silver.
