GO is transformed to exfoliated GO by high-energy ball milling in inert atmosphere using a Tetsch PM 100 ball-mill machine. GO and ethyl alcohol were placed into the milling machine. The GO powder was ball-milled for 40 h at 500 rpm in atmospheric condition with seven balls (made from zirconium oxide) of diameter 5 mm (Fig. 2 ).

Properties of ball milled thermally treated hemp fibers in an inert atmosphere for potential composite reinforcement. Bhuwan M. Prasad 1, Mohini M. Sain 1 & D. N. Roy 1 Journal of Materials Science volume 40, pages 4271–4278 (2005)Cite this article
The ball mill may be used with an inert atmosphere and therefore can be used to grind toxic and explosive materials. It is suitable for all degree of hardness and suitable for both batch and continuous operations. However, ball mill is a very noisy machine and wear would occur from the balls and casing which can cause contamination of the product.

Ball Mill. A ball mill is a grinding machine used to grind, blend, and sometimes for mixing of materials for use in geology, ceramics, metallurgy, electronics, pharmacy, construction material, and light industry, etc. Ball mills are classified as attritor, planetary ball mill, high energy ball mill, horizontal ball mill, or shaker mill.
The high-energy ball milling process is performed in a planetary type mill under an inert atmosphere, and at various milling times (15, 20 and 30 h). The microstructure and the morphology of the as obtained alloy powders are investigated by X-ray diffraction (XRD) and scanning electron microscopy (SEM).
During a ball tube mill start-up, Riley Power Inc. recommends a specified steam flow rate to be introduced and mixed with the primary air entering the mill to establish an inert atmosphere in the mill. During mill shut down, the same inerting process starts when the coal feeder is stopped or mill coal inventory reaches a certain level.
concentration in the mill approaches the threshold value, inert gas, regulated by the compressor, "reconditions" the atmosphere in the mill. To avoid overpressure a valve to environmental atmosphere opens, which explains the short periods of elevated O 2 concentrations.
