Working Principle of Rolling Process: The rolling process is a metal forming process, in which stock of the material is passed between one or more pairs of rollers in order to reduce and to maintain the uniform thickness. This process is mainly focused on the crosssection of the ingot or the metal which is .
Roller mills are used around the feed mill to perform a variety of tasks. Appliions include crumbling pellets, cracking corn, dry rolling and steam flaking grain, and grinding corn, wheat, or milo for mash and pelleted feeds. While each appliion has some unique aspects, maintenance and operation of the equipment is remarkably similar.
An MVR mill may have up to six grinding rollers and up to six drive units. Thus both systems are actively redundant meaning that one or several rollers can be taken out of the system for maintenance work while mill operation continues. The same applies to the independent drive modules of the MultiDrive ®.
