Studies on Scale-Up of Ball Mills | SpringerLink

Data from ball mills with a wide range of diameters are analyzed using detailed mathematical/numerical models. Analysis shows the relative power inefficiency of large ball mills is due to their inefficient breakage of coarse particles. The models developed can be used to scale-up mill behavior. The behavior of large mills at Bougainville and Pinto Valley is compared.

Mill (grinding) - Wikipedia

A mill is a device that breaks solid materials into smaller pieces by grinding, crushing, or cutting. Such comminution is an important unit operation in many processes. There are many different types of mills and many types of materials processed in them. Historically mills were powered by hand (e.g., via a hand crank), working animal (e.g ...Advanced technologies for a new 20-roll mill standmathematical preset models The solution package for the 20-high roll stand consists of technological controls for thickness control and an adaptive preset model to determine the setpoints of the rolling mill.
