Vertical roller mill maintenance can be broken down into three general areas; rolls, bearings, and drives. In order to achieve best roll life and consistent performance from end to end the rolls must be parallel and tram. If rolls are allowed to operate out of parallel, not only is the product inconsistent (fine on one end, coarse on the other ...
