Ball mills, like the three roll machine, are a common occurrence in industry, for the production of fine particles. during the ball milling process, there are two factors that contribute to the exfoliation. the main factor contributing is the shear force applied by the balls. using only shear force, one can produce large graphene flakes.

The operating principle of the ball mill consists of following steps. in a continuously operating ball mill, feed material fed through the central hole one of the caps into the drum and moves therealong, being exposed by grinding media. the material grinding occurs during impact falling grinding balls and abrasion the particles between the balls. then, discharge of ground material performed.

Grinding (rod) or (ball) mill type d has single weld, triple flanged, construction which means the shell is furnished in two sections, flanged and bolted in the center. all flanges are double welded as well as steel head to shell, note design. tumbling mill (rod or ball) mill type e has quadruple flanged construction. this also furnishes mill.
