One of the most used tumbling mills is the ball mill. This paper reviews different types of grinding media that have been developed and improved over the years and their properties.
Ball end mills, or ball nose end mills, are used for drilling shallow holes, slotting a channel where a flat bottom is not required or most commonly used to produce multi-dimensional contours in molds or dies. The design of ball end mills forms a hemispherical cutting action identical to the diameter of the tool.
The characteristic tumbling motion of these mills has given them the name 'tumbling mills', which include the ball mill, tube mill and rod mill. Ball mills are horizontal rotating cylindrical or conical steel chambers, approximately one third to half full of steel, alloy steel or iron balls, like that shown in Fig. 4.10 A–C, or flint stones.

Grinding test results for zinc ore showed that it is possible to decrease the total grinding energy consumption from 20.11 to 11.40 kW h/t by using vertical roller mill instead of AG/SAG-ball mill circuit (van Drunick et al., 2010).
Grinding test results for zinc ore showed that it is possible to decrease the total grinding energy consumption from 20.11 to 11.40 kW h/t by using vertical roller mill instead of AG/SAG-ball mill circuit (van Drunick et al., 2010). In another test performed in the Loesche test centre in Germany, 22.9% in airflow-mode and 34.4% energy savings ...
The voids (or interstitial space) within a rod load are approximately half those in a ball mill grinding load. Rods in place weigh approximately 400 pounds per cu. ft. and balls in place approximately 300 pounds per cu. ft.. Thus, quantitatively, less material can progress through the voids in the rod mill grinding media than in the ball mill ...
