Yes. The right speed is critical to the success of a ball mill. Too fast and the charge just spins around the outside of the jar. Too slow and the charge just slides. You want a cascade. The right speed is a function of the jar's internal diameter. According to Cardew, the right speed is 64 to 87% of critical speed, which can be found

Mill Speed - Critical Speed - Paul O. Abbe

Calculating how fast a Jar needs to spin is a little tricky, but simple one you know the factors. We need to know the inside diameter of the mill, that determine what speed we want, the outside diameter of the mill and the diameter of the rollers. The last two diameters will tell us how fast the roller has to spin to achieve our Jar speed.

Mill Critical Speed Calculation

The mill was rotated at 63% of the critical speed. The position of the balls at the end of five revolutions is shown in Figure 2. It is seen that, using a low coefficient of friction at the walls, balls tend to flow down the surface of the charge, and a "toe" begins to form. As the friction at the wall increases, cataracting motion is observed.
