Grinding equipment widely used in concentrators is a ball mill and a rod mill. The two have similarities in shape and grinding principles, but there are also differences in structure, performance ...
In recent times, these mills have successfully replaced the conventional rod mill–ball mill configurations. In Australia, the number of AG/SAG mills increased from about six in 1984 to more than 40 in the following 5year period [1] .
The rod mill and the ball mill belong to the mineral processing are similar in appearance and grinding principle, but there are differences in structure, performance and application. This paper summarizes the three aspects of the ball mill and the rod mill, hope to help you choose the right equipment for your own project.
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 ...
Configuration of ball mill and rod mill. The proportion of cylinder shape is different. The cylinder lengthdiameter ratio of rod mill is generally, while the cylinder lengthdiameter ratio of ball mill is smaller, only slightly greater than 1.

Rod mills are less common than ball mills for grinding minerals. The rods used in the mill, usually a highcarbon steel, can vary in both the length and the diameter. However, the smaller the rods, the larger is the total surface area and hence, the greater the grinding efficiency.
Based on these observations the combination of mill speed and liner configuration that gives the highest practical ball trajectories is recommended for coarse ball milling. For fine grinding (normal rod mill product) mill efficiency and rotational speed are less interdependent (Gow et al, 1934), and therefore slightly reduced speeds may be ...

Ball mills and rod mills are grinding equipment widely used in concentrators. The two have similarities in shape and grinding principles, but there are differences in structure, performance, and use. This article analyzes their similarities and differences from seven aspects, and tells you how to choose ball mill and rod mill!
Please note: *depending on feed material and instrument configuration/settings Function Principle The ball and the rod mill basically have the same concept comprising either a 12x12'''' jar with grinding balls or a 12x24'''' jar with grinding rods.

It would be impossible to treat this volume of material with any degree of is the intention in this paper to describe the simplest and generally the most typical circuit wherein a single rod mill and ball mill operate in parallel. Some of the subject matter will not be entirely applicable to every installation.
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 pieces, so that they can exit ...
