Mill (grinding)

Mill (grinding)

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%.

Size reduction with Planetary Ball Mills Macrolab

retSCH Planetary Ball Mills are used for the pulverization of soft, fibrous, hard and brittle ma terials. They achieve a very high final fineness down to the submicron range. The feed size depends on the mill and can be as large as 10 mm. If the sample feed size is larger than this then the sample must first undergo preliminary size reduction.
