Rolling schematic view Rolling visualization. In metalworking, rolling is a metal forming process in which metal stock is passed through one or more pairs of rolls to reduce the thickness, to make the thickness uniform, and/or to impart a desired mechanical property. The concept is similar to the rolling of is classified according to the temperature of the metal rolled.

over a series of vacuum boxes and then over a couch roll. Often, a dandy roll is located on top of the forming fabric over the suction boxes. This is a light open structured roll covered with wire cloth, resting lightly upon the surface of the sheet. Its function is to flatten the top surface of the sheet and improve the finish. A pattern on the

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. Even though the feed rate averaged out over time may be within acceptable limits, the instant the surge hit the roll the feed rate
