22 May, 2019. The ball mill consists of a metal cylinder and a ball. The working principle is that when the cylinder is rotated, the grinding body (ball) and the object to be polished (material) installed in the cylinder are rotated by the cylinder under the action of friction and centrifugal force. At a certain height, it will automatically ...

Ball and Rod Mills. JeanPaul Duroudier, in Size Reduction of Divided Solids, 2016. Performance. Rod mills are used in an open circuit between crushing and the ball mill. They often operate in wet and where the pulp contains up to 50% solid by mass. This machine is equally very applicable to dry where it could take a feed that has achieved 6% moisture.

While adding a 5 th flute to a 4 flute tool theoretically gives you 25% more material removal per revolution with an appropriately increased feed rate, feeding the tool that much faster may overload the tool. The 25% increase in material removal is more likely closer to 1015%, given the tool is exactly the same in all other specifications.

One way to calculate a ball mill's grinding efficiency is to divide its total static horsepower (TSH) by its total theoretical tonnage (TPT). This number can then be used to compare different types of mills. A TSH of hp/tonne is considered to be very efficient, while a TSH of hp/tonne is considered to be moderately efficient.
