Worn roller grinding surfaces can either be replaced or rewelded inside the vertical roller mill. If needed, the roller swingout feature allows easy removal of rollers to perform maintenance work of common parts is possible across different vertical roller mill sizes for both cement and raw applications.
Ever since the roller mill was first introduced to the cement industry, its system capacity has continued to evolve. With the increasing capacity of the mills, the output torque of the gearbox, its main design criterion, had to be increased accordingly (see Fig. 1). These increasing mill sizes have brought the currently used gearbox concepts to
grinding of raw materials.
