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 C-model or 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.

Area of a sector. The formula for the area of a sector is (angle / 360) x π x radius, but the diameter of the circle is d = 2 x r, so another way to write it is (angle / 360) 2 x π x (diameter / 2).Visual on the figure below: Since a sector is just a slice from a circle, the formula is quite similar to that for the area of a circle, with the difference needed to calculate what part of …
