Ball Millsan overview | ScienceDirect Topics

It is possible to make an approximate calculation of the capacity of a ball mill with uneven armor by means of the equation: NCylindrical Ball Mills differ usually in steel drum design (Fig. 2.11), which is lined inside by armor slabs that have dissimilar sizes and form a rough inside surface. Due to such juts, the impact force of falling balls is strengthened. The initial material is fed
