Ball mills can be as small as lab-scale mills or as large as industrial mills with a diameter of up to 8 m. The mill's capacity is dictated by its volume. The volume depends on both diameter and length. Generally, the length-to-diameter ratio of the mill, known as the L/D ratio, is between 0.5 and 3. Shorter mills are used for crushing coarse ...

Critical Speed: Critical speed is the hypothetical speed at which the centrifugal force is equal to the gravitational force, and the grinding media starts sticking to the inner shell of the equipment instead of falling freely.Grinding at or close to critical speed of the mill yields a poorer grinding efficiency. The ball mills are mostly operated at 65 …

Working Principle of a Ball Mill. The working principle of a ball mill is based on the rotation of the drum, which causes the grinding media to fall onto the material to be ground. The force of impact breaks the material into smaller particles, while the friction between the balls and the material causes further grinding and refinement. The ...

Mill scale is less reactive (more "noble") than the steel underneath, and consistent with the behaviour of two dissimilar metals when in contact, the more reactive metal (in this case steel) will oxidise (rust) at the expense of the less reactive metal (mill scale). The mill scale in fact looks like a scale and it can "pop off" the
