Ball milling is a mechanical technique that is broadly used to grind powders into fine particles [134141]. The reactants are generally broken apart using solvent molecules in the traditional method; but in ball milling, reactants are broken by using mechanical forces. The term mechanochemistry has been introduced very recently [142].
This critical speed ratio [r C] can be derived by taking the equilibrium of centrifugal force acting on the ball during milling from the rotation of the pot and the revolution of the disk, as follows: Two centrifugal forces ([F p] rotation, [F r] revolution) are derived from Eqs. (4), (5).

The mill speed affects the power proposal. A builtin barrier for increasing the mill speed is the phenomenon of centrifuging at a nearly critical speed. Stirred ball mills, in contrast, feature a highspeed rotor and an installed grinding chamber. By using compressionshear action, grinding is caused.
In ball milling, the speed of the rotation is more important. At a low speed, (a), the mass of the ball slides or rolls over each other with inefficient output. ... (50 to 80% of the critical speed), (c), the centrifugal speed force just occurs with the result that the balls are carried almost to the top of the mill and then fall to ...

A distinction is made between mills which have an overcritical speed of rotation and mills which have a subcritical speed of rotation. It is known that the critical speed of rotation in the case of mills is that speed of rotation at which the centrifugal force exceeds the weight of the members, as determined by the force of gravity.
These were milled together with PHBV using a centrifugal ball mill at 650 rpm for 60 minutes. The resulting composites were then moulded in a hot press to form thick films. The dispersion of the CNCs within the polymer matrix was studied by SEM, which showed a good dispersion and distribution of the crystals within the nanocomposites.
