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 …
Ball mills cab be used equally well for wet or dry grinding. In the case of wet grinding the particles are also dispersed in the liquid medium. For temperature sensitive products, ball mills can be fully jacketed to maintain temperatures of the product. Ball mills scale up well and in fact improve in performed with increasing size.
