Supreme Roll Mill®

Supreme Roll Mill®

The SUPREME ROLL MILLS provide dependable size reduction of a wide variety of solids. They utilize two cylindrical rollers to fracture the material with an efficient, once-through milling action. These units can produce output sizes from 4-70 mesh and produce output in an extremely narrow size range and do so without degradation of the material. These results are impossible to accomplish with any other size reduction technology. The Rolls are available in smooth or corrugated roll configurations in order to meet exacting output size and consistency requirements.

The Franklin Miller SUPREME ROLL MILLS comes in one, two and three high configurations. It is built with spring release roll protection that will allow the rolls to separate when hard foreign materials such as rocks, nuts, bolts, tools etc. pass through the mill. This allows for a much longer life due to the ability to avoid damage. The rolls are cast with magnesium, chrome, molybdenum and iron. Our rolls do not require tempering (flame hardening) which warps lower quality rolls and are thick enough to be re-corrugated 6 to 8 times before they must be replaced.


SUPREME ROLL MILLS are manufactured in a number of sizes and configurations to handle the most exacting size reduction requirements. Rolls can be supplied water cooled or heater. A variety of roll styles are available including smooth, serrated, and grooved. By varying the gap between the rolls and the pressure or speed, output mesh sizes are precisely controller. Units can be designed with easily removable hopper, inlet feeder, or they can be provided with inlet flanges for easy connections to chutes, kettles, or tanks. SUPREME ROLL MILLS are available in single, tandem, or triple pass configurations depending on reduction ratio required. These units may be supplied complete with pre-breaker where required.


Typical applications include coffee, food, fine chemicals, fertilizers, detergents, pharmaceuticals, minerals, cracking and flaking corn and grains, and precise reduction of polymers. Fabricated in carbon steel with chilled iron rolls, stainless steel, and in special alloys as required.
