     · A Forging reduction is generally considered to be the amount of cross-sectional reduction taking place during drawing out of a bar or billet. The original cross-section divided by the final cross-section is the forging ratio (say 3 1). There is an equivalent reduction on upsetting for forgings being upset during forging (gear blanks for example).

    The power needed to operate a rod mill could exceed 30 of the power used in a ball mill. When they are worn rods must not stretch but break in rather small pieces so that they can exit the mill. The energy consumed by rod mills could be from 10 to 30 higher than the energy consumed by bar mills and this is for comparable performance.
