Mill (grinding) - Wikipedia

Mill (grinding) - Wikipedia

Ball mill. A typical type of fine grinder is the ball mill.A slightly inclined or horizontal rotating cylinder is partially filled with balls, usually stone or metal, which grind material to the necessary fineness by friction and impact with the tumbling balls. Ball mills normally operate with an approximate ball charge of 30%.

Hausner Ratio is V 0 /V F .; V 0 is unsettled apparent volume; V F is final tapped volume; The Hausner Ratio is measure of the propensity of a powder to be compressed as described above. As such it is measure of the powder's ability to settle, and it permit an assessment of the relative importance of interparticulate interactions.
