Provided is a method of producing pellets of a graphene-polymer composite, the method comprising: (a) mixing multiple particles of a graphitic material and multiple particles of a solid polymer carrier material to form a mixture in an impacting chamber of an energy impacting apparatus; (b) operating the energy impacting apparatus with a frequency and an intensity for a length of time sufficient for peeling off graphene sheets from the graphitic material particles and transferring the graphene sheets to surfaces of the solid polymer carrier material particles to produce graphene-coated polymer particles inside the impacting chamber; and (c) feeding multiple graphene-coated polymer particles into an extruder to produce filaments of an extruded graphene-polymer composite and operating a cutter or pelletizer to cut the filaments into pellets of graphene-polymer composite. The process is fast (hours as opposed to days of conventional processes), environmentally benign, cost effective, and highly scalable.

The present invention provides a method for preparing two or more batches of material. A first batch is placed into a first container and a second batch is placed into a second container. A grinding media is added to each of the first and second containers. The first and second containers are placed into a movable body, which is moved to induce movement of the first and second containers at least under gravitational force in the movable body so that the grinding media grind the first and second batches inside their respective first and second containers. A system is also provided.
