Recommendation of ball mill and rod mill Ball mill and rod mill are suitable for different materials 1. Selection by material's hardness Ball mill has a strong adaptation of material, and it is suitable for grinding hard materials, such as slag, iron ore, copper ore, etc. Rod mill is suitable for grinding brittle material, such as rare metals.
When the mill is rotated without feed or with very fine feed, the rods are in parallel alignment and in contact with one another for their full length. New feed entering at one end of the mill causes the rod charge to spread at that end. This produces a series of wedge shaped slots tapering toward the discharge end. The tumbling and rolling rods expend most of their crushing force on the
The rod mill adopts overflow type and open type discharge, does not use grate type discharge. The diameter of the rod mill discharge end is larger than that of the same size ball mill. When the rod mill speed is lower than the working speed of the same size ball mill, the medium in the rod mill is in a sloping working state.

09/04/2015· Fig 1 Cross sections of a rod mill and a bar mill. Ball mills. 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
Essa® laboratory ball and rod mills achieve excellent size reduction no matter what your application. Use them to mill and grind soft, hard, brittle and fibrous materials, either in a wet or dry state. They’re quick, efficient and known to achieve reliable results
As such, when the product is sticky, rod mills are preferred over ball mills. Rod mills have an industrial yield that is less than that of a ball mill, which explains the fact that balls have a much larger grinding surface than rods. The power needed to operate a rod mill could exceed 30% of the power used in a ball mill. When they are worn, rods must not stretch but break in rather small

A ball mill is a type of grinder used to grind or blend 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 its axis. The axis of the shell may be either
