Get DetailsSep 15, 2017 Lane Dederer. There are multiple factors affecting the velocity a ball gains while descending an inclined plane. One simple factor that will affect the velocity of a ball rolling down an incline is the angle of the incline. This is due to the fact that when the angle of the incline is increased, the height of the incline also increases.

We changed the slope α of the incline in different blocks of trials, and randomized the starting position of the ball on the incline (resulting in different durations of ball motion) across trials. Accordingly, ball acceleration on the incline and speed at the time of interception varied by about.
Get DetailsIf a ball mill uses water during grinding, it is a ‘wet’ mill. A typical ball mill will have a drum length that is 1 or 1.5 times the drum diameter. Ball mills with a drum length to diameter ratio greater than 1.5 are referred to as tube mills. Ball mills may be primary or secondary grinders.
