Ball Mill (Ball Mills Explained)
If a ball mill uses little or no water during grinding, it is a 'dry' mill. If 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.

Study of ball screw system preload monitoring during operation based …
The ball screw preload level usually decreases due to wear and tear of the ball after it has been in operation for a long time. This then leads to a decrease in the stiffness of the ball screw feed drive system, and consequently to decreases in the stiffness of the corresponding machine axis, strong vibrations, and machine positioning accuracy.
