CAUTION! Because the tool spins on a mill, hot chips can be thrown much farther than when using a lathe. Safety glasses and proper clothing are a must for all milling operations. Milling on a vertical mill is usually accomplished with end mills. These cutters are designed to cut with both their side and end. (See Figure 12.)

A ball mill is a crucial piece of machinery used in grinding and mixing materials in various industries. It works by rotating a cylinder with steel or ceramic balls, causing the balls to fall back into the cylinder and onto the material to be ground.

Previous studies (Mazzinghy, 2012, Mazzinghy et al., 2012) have shown that the higher efficiency of the vertical mill produces larger values of the selection function when compared to the ball mill selection function, by a constant parameter S1 E, from Eq. (5), is multiplied by a scaling factor equal to to correct for the higher efficiency of the vertical mill.

One comment that I did not see here is the potential for differential grinding, especially in vertical mills, but also in ball mills. That is when intergrinding different materials, the softer materials tend to be ground finer. In air swept vertical mills, this can leave a higher quantity of the harder to grind material in the mill.
