Figure Displacement of balls in mill. where D m is the mill diameter in meters. The optimum rotational speed is usually set at 6580% of the critical speed. These data are approximate and may not be valid for metal particles that tend to agglomerate by welding. The minimal magnitude of ball size is calculated in millimeters from the equation:

The flow of lubricating oil is. monitored in the oil flow divider by a speed monitor and the oil pressure is. monitored by the pressure switches (160 and 400). Moreover, the oil pressure is. reduced by pressure limiting valves (140 and 380) in order to avoid overloading.

You also need a rod mill work index to design a ball mill operating on a coarse feed, above about 4 mm. Q1: You design for a typical percentage of critical speed, usually 75% of critical. Then you iterate the mill diameter using a Morrell Cmodel or Nordberg equation to get the RPM that corresponds to 75% for that mill diameter.

A ball mill also known as pebble mill or tumbling mill is a milling machine that consists of a hallow cylinder containing balls; mounted on a metallic frame such that it can be rotated along its longitudinal axis. The balls which could be of different diameter occupy 30 50 % of the mill volume and its size depends on the feed and mill size.
