Fig. S4† shows the thermogravimetric analysis of the ball milled graphite.The heating process was programmed to be the same as the annealing process. C 1 shows little weight loss during the annealing. Both C 2 and C 4 show a weight loss about 3% below 100 °C, which might be contributed by the absorbed moisture. We noticed C 2 has steady mass …

In a ball mill circuit, the "output" can be defined as the production rate of fines of the circuit. As for any output, ball mill circuit output is a function of both its inputs and efficiencies. There are two "inputs" to a ball mill circuit: the ore fed to the circuit and the power delivered by the grinding mill.

The ball mill is a popular tool choice amongst mechanochemical researchers. Widely available in a variety of sizes and designs, these devices contain one or more loose balls that crush whatever is inside them as the vessel is shaken or rotated. Both compressive and shear forces are put on any molecules inside.

Ball end mills produce a radius at the bottom of pockets and slots. Ball end mills are used for contour milling, shallow slotting, contour milling and pocketing applications. Flutes Spiral-shaped cutting edges are cut into the side of the end mill to provide a path for chips to escape when an end mill is down in a slot or a pocket.
