Roller mill - Wikipedia. Five- and six-roller mills Six-roller mills have three sets of rollers. When using this type of mill on grain, the first set of rollers crush the whole kernel, and its output is divided three ways: Flour immediately is sent out the mill, grits without a husk proceed to the last roller, and husk, possibly still containing parts of the seed, go to the second set of rollers.
Wegmann's roller mill was made of fragile porcelain wheels and it was a simple structure of grain mill grinding mechanism. Mechwart changed the porcelain wheels to wear-resistant, hard cast, obliquely grooved grinding rolls and he used strings to clamp the grinding rolls and covered the roller mill as well.
