To accelerate the math orcalculationyou can use the shortenedformula: D m <= Km * d^0.5where Km =6 (log dk) is taken from Figure 5 according to the fineness of the finished product dk. Theseformulasare applicable to the case of feeding amillwith only single-sizedballsand not a mixture without consideration forball wear.

Operation and Elements of a Closed CircuitBall MillSystem.Cement ball millstypically have two grinding chambers. The first chamber is filled with larger diameter grinding media and lined with lifting liners. The first chamber coarse-grinds the feed material and prepares it for the second chamber. The second chamber is the fine grinding chamber.

Dec 11, 2018· Q: what is the throughput in aball millif i feeding say 170tph what is the throughput in aball millif i feeding say 170tph A: The output of aball millequals the feeding rate. We cannot create mass in aball mill(or any other process). So conservation mass means that what goes in must come out. • Back to Top
Planetary Ball MillWorking Principle. PlanetaryBall Millsconsist of several cylindrical grinding jars (positioned on thesunwheel as shown on the figure) which are filled with loose grinding balls. Two superimposed rotational movements move the grinding jars: Like in a planetary system the grinding jar rotates on a orbit around the centre.
