Calculate and Select Ball Mill Ball Size for Optimum Grinding

In Grinding, selecting (calculate) the correct or optimum ball size that allows for the best and optimum/ideal or target grind size to be achieved by your ball mill is an important thing for a Mineral Processing Engineer AKA Metallurgist to do. Often, the ball used in ball mills is oversize “just in case”.

OverviewWorkingApplicationsDescriptionAdvantages of the ball millVarietiesSee also

A ball mill is a type of grinder used to grind, blend and sometimes for mixing of materials for use in mineral dressing processes, paints, pyrotechnics, ceramics and selective laser sintering. It s on the principle of impact and attrition: size reduction is done by impact as the balls drop from near the top of the shell. A ball mill consists of a hollow cylindrical shell rotating about its axis. The axis of the shell may be either horizontal or at a small angle to the horizontal. It is partially filled with balls. The grinding media are the

CALCULATION OF MAXIMUM BALL SIZE FOR BALL MILL GRINDING

Jun 25, 2018  Mill effective diameter = 2.23 m . 335 is a constant used for dry grinding with steel balls in the mill. Actual size of media is taken is lower than the calculated value. It is around 80 to 90 mm. If you Wants to reduce the maximum ball size, thenreduce the feed size by using pre-grinding operation.

Bal-tec - Ball Diameter Calibration

The second approach to ball diameter calibration is the so-called absolute method.

A micrometer or thread-driven measuring machine is an example of the absolute concept.
