prevent a recurrence of the problem. For example, take an appliion with ineffective seals. When contaminants in the form of particles get into the bearing through the seals, they can be overrolled by the rolling elements. The overrolling creates indentations in the raceways († fig. 1). Hard particles may cause inden tations with sharp ...

Roller mills are also more sensitive to instantaneous changes in the feed rate than are other pieces of process equipment. Feeding a roller mill directly from a screw conveyor or bucket elevator will cause surges in the feed rate that the roller mill "sees" instantaneously unless some damping system such as a surge hopper is used.

the adoption of vertical roller mills as the grinding mill solution and a flotation flowsheet which achieves metal recovery at a much coarser grind size than was previously considered in the design. This lower power usage has resulted in a reduction in operating costs, while the use of dry grinding from the vertical roller mills has also

•In vertical mills, milling cutters with solid shafts are usually used. Milling cutters with keyed holes are predominantly for use in horizontal mills. End mills are designed for cutting slots, keyways and pockets. Two fluted end mills can be used to plunge into work like a drill. End mills with more than two flutes should not be plunged into the
