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., horse mill), wind or water ().
This mining industry energy bandwidth analysis was conducted to assist the Industrial Technologies Program's (ITP) Mining subprogram, an initiative of the U.S. Department of Energy's (DOE) Office of Energy Efficiency and Renewable Energy (EERE), to maximize the impact of its R&D in reducing industrial energy consumption.
Grinding accounts for over 40% of the energy expenditure of a mining complex (Ballantyne 2012) and the energy efficiency of grinding with respect to surface energy is only about 1% to 5% (Lowrinson 1974). Therefore, there is a potential for improvement. Several approaches are …

HPGR or high-pressure grinding rolls have made broad advances into nonferrous metal mining. The technology is now widely viewed as a primary milling alternative, and there arc a number of large installations commissioned in recent years. After these developments, an HPGR based circuit configuration would often be the base case for certain ore types, such as very hard, abrasive ores.
8-3 Centrifugal force outward Fc mp& 2 Dm 2 (8.1) & is the angular velocity, mp is the mass of any particle (media or charge) in the mill and Dm is the diameter of the mill inside the liners. Gravitational force Fg mpg (8.2) The particle will remain against the wall if these two forces are in balance ie.
