It is rather recommend changing reaction time than frequency. Start with 75- of the maximal operation frequency of the ball mill. The thermal stress for the reactants could be reduced by using cycled mode: mill for a. specific amount of time – 5-10 min pause – start milling again and repeat the procedure for the required amount of time.

The approximate horsepower HP of a mill can be calculated from the following equation: HP = (W) (C) (Sin a) (2π) (N)/ 33000. where: W = weight of charge. C = distance of centre of gravity or charge from centre of mill in feet. a = dynamic angle of repose of the charge. N = mill speed in RPM. HP = A x B x C x L. Where.

Mesin ball mill merupakan mesin penggiling yang sangat canggih. Mesin ini mempunyai prinsip kerja yang sangat efektif dan efisien.
