Discover MoreSo, the general rule of thumb for rod mills is to operate no faster than the speed that will obtain the desired product size. The operation speed of rod mills is generally determined by the Peripheral Speed of the Inside of the mill. Generally, rod mills operate between 280 feet per minute and 480 feet per minute at the periphery of the mill.
