The effect of roll diameter on mill capacity

The throughput of a mill is related to the size of its rollers and the required level of performance. The effect of roll length and roll diameter on capacity (throughput at a given level of performance) is of interest because the size of the rollers strongly influences the installed cost of a mill. The effect of roll diameter on the capacity of a mill is not well established. It is complicated by a likely interaction with mill speed. A rudimentary, theoretical approach is used to advance the thesis that mill capacity is fundamentally proportional to the diameter of the mill rolls.
