The typical Roller Mill System is designed to dry, pulverize, and classify a wide variety of materials ranging from a moh hardness of 1 to 5. In feed sizes range from ½ inch to 2 inches. Roller mills can roduce particles ranging from coarse granular products ( 90% minus 10 mesh ) to as fine as 99.99 % minus 15um (when coupled with a Micro-Sizer RMC®). The Roller Mill can also be used to prepare feed for systems producing ultra-fine materials such as Ball Mills, Impact Mills, Trough mill® or the Micro-Sizer® Air Classifier.
