Tower mills consist of a stationary, cylindrical grinding chamber filled with grinding media (such as steel or ceramic balls). They use a rotating screw agitator which generates a strong recirculation within the mill as media is conveyed upwards inside the flights of the screw and flows downwards outside the screw. The tower mill has
