Graphite Applications for Wet & Dry Grinding Attritors Graphite is a crystalline form of pure carbon. Its structure consists of sheets of hexagonal networks that are one atom thick. Because the sheets are poorly connected, they easily slide against one another when subjected to even a small amount of force, contributing to graphite's relatively low
