    Solved: The function of a steel plate mill is to roll ...

    The function of a steel plate mill is to roll reheated slabs into plates of scheduled thickness and dimension [5, 10]. The final products are of rectangular plane view shapes having a width of up to 3300 mm and a thickness of 180 mm. A schematic layout of the mill is shown in Figure. The mill has two major rolling stands, denoted No. 1 and No. 2.

    Sep 13, 2018 “Prior to milling, cleaning and conditioning of the grain is the most important aspect of milling. The number of break passages can vary according to the size of the mill. If, for example the mill is designed with five passages for maximum extraction and the number of roller mills in each passage is below the certain minimum, this will not assist in the milling operation to obtain the best ...

    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 rider roll also performs a safety function, helping to keep the roll set in place on the drums. For that reason, relief pressure is never allowed to actually lift the rider roll off the paper rolls. Pressure plus weight. At the beginning of the roll set, the downward pressure of the rider roll makes up for the lighter weight of the rolls.
