The Ball Mill. Much like all types of mills, the Ball Mill's purpose is to grind and blend material into smaller pieces. To do this, the material is fed into the cylinder at an angle and then rotated inside. During rotation, the material travels up the internal wall of the cylinder and then falls back down to the bottom of the structure.

Figure 4 Lab Mill with Wood Ball Charge (left) and in Operation (right) Once the instrumented ball was placed within the mill, with the wood balls, the mill was allowed to reach steady state prior to the data collection. This was possible since the instrumented ball has a timer, 1.1708 +/- 0.0001 allowing it to delay certain actions.

A ball mill is an example of a comminution method which produces size reduction by both impact and attrition of particles. Ball mills consist of a hollow cylinder mounted such that it can be rotated on its horizontal longitudinal axis. Cylinder diameters can be greater than 3 m, although much smaller sizes are used pharmaceutically.
