In the 19th century roller mills were adapted to grist mills before replacing them. The mill used either steel or porcelain rollers. Between the years 1865 and 1872, the Hungarian milling industry upgraded and expanded the use of stone mills combined with roller mills in a process known as Hungarian high milling.
Feeding a roller mill directly from a screw conveyor or bucket elevator will cause surges in the feed rate that the roller mill "sees" instantaneously unless some damping system such as a surge hopper is used. Even though the feed rate averaged out over time may be within acceptable limits, the instant the surge hit the roll the feed rate

Three roll milling is a dispersion technique that employs both shear flow and extensional flow created by rotating rolls of different speed to mix and disperse CNT, CNF, Graphene, or other nanoscale particles into polymers or other viscous matrixes. It is a very appealing process that benefits the environment by eliminating the solvent.
Best practices for safe and efficient three roll milling Theory of operation . A three roll mill is composed of three horizontally positioned rolls rotating in opposite directions and at different speeds. The material to be milled is placed between the feed and center rolls and gets transferred from the center roll to the apron roll by adhesion.
Roller mill is a form of compression mill that uses a single, double or triple cylindrical heavy wheel mounted horizontally and rotated about their long axis either in opposing pairs or against flat plates, to crush or grind various materials.
