granted in 18th century and was related to the tandem mill which were using copper and brass as the rolling materials. In year 1783, after the entry of grooved rolls the rolling production increased up to 15 times and that was the start of modern rolling mill. While reviewing the design of rolling mill components our
the parameters of the mill. In another approach, the energy efficiency of milling may be improved by adjusting the parameters of the comminuted material with the use of chemical additives or water. Chemical additives may, however, have a negative environmental impact [22]. Energy savings may also be found in the ball mill drive systems.
