Consistent grinding and balancing of rolls is necessary for efficient operation and optimum paper quality. As an integral part of a modern roll maintenance program, roll grinding and balancing uses machinery with accurate inspection and measurement equipment. This paper provides practical tips on roll inspections, balancing, grinding and grooving.
Mills. Figure 2 shows a cutaway view of a Babcock and Wilcox MPS Pulverizer. Ring-Roll and Ball-Race Mills A ball or roller between two races or rings provides the grinding surfaces on which pulverization occurs. One or both of the races may rotate against a ball or roll (in a Ring-Roll Mill the rolls may rotate while the ring is stationary).
