Vibratory Micro Mill PULVERISETTE 0 / Description - fritsch.de

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%.

SAG Mill Comminution (SMC) Test® The SMC Test® is conducted on a single size range which is typically -31.5 mm +26.5 mm, hence the sample requirements are less than drop weight test. The test generates the Drop Weight Index (DWI) which is expressed in KWh/m 3, which strongly correlates to values generated from a Drop Weight Test.
