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.
statistics, 95% of roll breakups is a result of surface and subsurface flaws, and only 5% of breakups are due to internal flaws [1, 2]. The decrease of mill rolls destruction which cause a material losses will allow to aggrandize the effectiveness of mill products. In this present main attention devotes to sheet rolling mills.
