Calculating Mill Drive RPMs: Is Your Mill Up to Speed? By Robert A. Sladky Vice President Tube Mill Engineering Many "W" style mills that have the ability to shim up the bottom driven shafts in each section to maintain metal line after tooling is reworked, and are many times also equipped with a individual motor drive in each of the three sections as illustrated below.

rolling mill horsepower calculation. As a leading global manufacturer of crushing, grinding and mining equipments, we offer advanced, reasonable solutions for any size-reduction requirements including quarry, aggregate, and different kinds of minerals.

Horsepower (hp) is a unit of measurement of power (the rate at which work is done). There are many different standards and types of horsepower. Two common definitions being used today are the mechanical horsepower (or imperial horsepower), which is about 745.7 watts, and the metric horsepower, which is approximately 735.5 watts.
