A typical layout of a mill using the kraft chemical pulping process is shown in figure 2-1. Mechanical, semichemical, and sulfite pulp mills differ in detail, particularly in wood preparation, fiber separation, and bleaching, but many of the downstream refining, bleaching, and papermaking processes are similar. Instead, the rider roll pressure acts together with the weight of the shipping rolls to influence the nip pressure between the shipping rolls and the drums. The drum nip pressure, in turn, helps the drums transfer their torque to the shipping rolls, thereby influencing roll hardness. Figure 4 Effect of nip pressure on roll hardness.

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.
