An active/resilient grinding media inside a tube containing a sample is oscillated rapidly by a homogenizer so that the active media is driven in a first direction until it impacts a first end of the tube, which causes it to deform and store an energy charge as it decelerates and stops, and it then accelerates rapidly in the second opposite direction under the discharging force of the stored energy toward the opposite second end of the tube. This cycle of the active media decelerating/charging and then discharging/accelerating is repeated throughout the entire oscillatory processing of the sample. The result is much higher velocities of the active media and therefore much greater impact forces when the sample and active media collide, producing increased efficiency in disruption and size-reduction of the sample particles.

Embodiments described herein relate generally to large scale synthesis of thinned graphite and in particular, few layers of graphene sheets and graphene-graphite composites. In some embodiments, a method for producing thinned crystalline graphite from precursor crystalline graphite using wet ball milling processes is disclosed herein. The method includes transferring crystalline graphite into a ball milling vessel that includes a grinding media. A first and a second solvent are transferred into the ball milling vessel and the ball milling vessel is rotated to cause the shearing of layers of the crystalline graphite to produce thinned crystalline graphite.
