The magnitude of that rotation is torque (τ), expressed in newton-meters (N∙m). The most basic way to calculate torque is to multiply the Newtons of force exerted by the meters of distance from the axis. There's also a rotational version of this formula for 3-dimensional objects that uses the moment of inertia and angular acceleration.

For overflow ball mills, the charge should not exceed 45% of the mill volume . For grate discharge mills, the charge should occupy about 50% of the mill volume . Bond developed a relationship that can be used to determine the percent charge by volume as a function of the vertical height above the charge, He, and the radius of the mill, R, i.e.,
Ball mill . The ball mill is a key piece of equipment for grinding crushed materials and it is widely used in production lines for powders such as cement silicates refractory material fertilizer glass ceramics etc as well as for ore dressing of both ferrous and non ferrous metals The ball mill can grind various ores and other materials either wet
Abstract. Equations are derived for the normal roll pressure, specific roll load and torque in hot rolling mills, using the condition for plastic deformation in rolling derived by Orowan, together with von Kármán's equation of equilibrium. Although applying strictly to the rolling of ideal plastic-rigid materials, these equations may be ...
parts include dead load of the rotator, load produced when the machine performs work, and load produced by transmission of dynamic force. These can theoretically be mathematically calculated, but calculation is difficult in many cases.
