    Size Reduction With Planetary Ball Mills

    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.

  • Variables In Ball Mill Operation Paul O Abbe

    Variables In Ball Mill Operation Paul O Abbe

    The formula for critical speed is CS = 1 2π √ (g (R-r) where g is the gravitational constant, R is the inside diameter of the mill and r is the diameter of one piece of media. This reduced to CS = 265.45 √ (R-r). Dry mills typically operate in the range of 50 -70 of CS and most often between 60 -65 of CS.
