When ball milling was not applied, only a 16.3% yield was achieved, whereas, after milling for 0.5–1 hour, the yield improved to 56.1–61.1% probably due to breakage of inter- and intra- molecular hydrogen bonds, with a consequent increase of hydroxyl groups available to react.

25.05.2019BALL SCREW: • A ball screw is a mechanical linear actuator that translates rotational motion to linear motion with little friction. A threaded shaft provides a helical raceway for ball bearings which act as a precision screw. As well as being able to apply or withstand high thrust loads, they can do so with minimum internal friction.

Ball screws are screw drives that convert a rotating drive motion into a linear motion in normal operation. Due to the favorable friction conditions and the associated very high degree of efficiency (90%), they are in principle not self-braking so that in reverse operation a linear drive motion can also be implemented in the rotational direction.
