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

The updrive type consists of a roll stand, mill spindles, a vertical gear reducer with a pinion stand and a motor. The gear reducer and motor are installed on a concrete frame to protect them from roll cooling water and mill scale. A lifting device is installed under the roll stand to adjust the caliber position to pass level.

The more common tworoll grain mill is as effective at the crush as it is simple: Feed the grist through two spinning rollers that crack the kernel, sheer the husk away, and crush the endosperm into uniform particles. It's the first operational process in the brewery, and it's easy to overlook its impact on beer quality.
