Common types of grinding mills include Ball Mills and Rod Mills. This includes all rotating mills with heavy grinding media loads. This article focuses on ball and rod mills excluding SAG and AG mills. Although their concepts are very similar, they are not discussed here. Photographs of a glass ended laboratory ball mill show action of ball mass within the mill. The action of other grinding

Because of this, the rod mill can effectively reduce 1″ feed size to 10 mesh or finer in open circuit. The voids (or interstitial space) within a rod load are approximately half those in a ball mill grinding load. Rods in place weigh approximately 400 pounds per cu. ft. and balls in place approximately 300 pounds per cu. ft..

Rod mill is a kind of cement ball mill used in cement plants. MBS series rod mills are used for further grinding after the raw material is broken. It is an essential machine widely used in the cement manufacturing plant.

Grind coarse feed material with a reliable Rod Mill that won't over-grind. If you are in need of an application for coarse materials like limestone, potash, coal, phosphate and bauxite, you may be looking for a solutions like Rod Mills. Rod Mills are particularly useful, if you run a low tonnage operation and are looking for coarse product.

In materials processing a grinder is a machine for producing fine particle size reduction through attrition and compressive forces at the grain size level. See also crusher for mechanisms producing larger particles. In general, grinding processes require a relatively large amount of energy; for this reason, an experimental method to measure the energy used locally during milling with different machines was recently proposed.

The following cost advantages should be considered when evaluating rod mill grinding: Rod Mills use low cost grinding media. Less power is required since grinding rods are not cascaded and operate at lower peripheral speeds. Higher grinding efficiency is obtained since there is less void space in a rod charge compared to any other grinding media.

Rod mills are grinding machine which employ high carbon steel or special steel rods of nearly the same length as that of the drum, in place of steel balls in ball mills. Rod mill products are generally coarser than those produced in a ball mill, and rod mills are well suited to handle coarser feed and to control the top size of the product.

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.
