Roller mills. Roller mills are basically of two distinct types. The first has a series of rollers which rotate around a central axis within a drum. The reduction takes place between the rollers and the drum. The second type is where there are a series of fixed rollers and a rotating table. The milling takes place between the rollers and the table.
