Rod mill. Unlike the ball mill, the grinding medium in the rod mill is a steel rod, so the working characteristics are significantly different from those of the ball mill. Since the steel balls are in point contact, the steel rods are in line contact. When the steel rods are sandwiched between the steel rods, the coarse particles are first broken, and the fine particles are protected to some ...

A ball mill is a type of grinder used to grind, blend and sometimes for mixing of materials for use in mineral dressing processes, paints, pyrotechnics, ceramics, and selective laser sintering. It works on the principle of impact and attrition: size reduction is done by impact as the balls drop from near the top of the shell. A ball mill consists of a hollow cylindrical shell rotating about ...

Ball mill (Fig 1) is same kind of mill as rod mill, except that it is filled with balls instead of rods. Because of balls have greater ratio of surface area than rods they are more suitable for fine grinding. Balls are also lighter, so the kinetic energy of a single dropping ball is smaller than a rod. The lining material is of great importance as there is a significant amount of wear taking ...
