MBS type rod mill is widely used for the grinding process which has high requirement for the uniformity of the ground final products in refractory, chemistry, metallurgy and glass industry, and it has also been used in building sand making industry in recent years.
In the grinding process, the grinding media make a line contact with ores, so it has a certain effect on selectivity and grinding. The particle size of dry rod mill product is relatively uniform. When used for coarse grinding, the processing capacity of rod mill is better than that of other ball mill with same specification, and the reverse is ...
The designs of tubular mills loaded with steel rods along its length as the grinding medium are described in this chapter. Details of operation and computations of mill capacities and the power consumption are explained with illustrative practical examples and solution of problems useful for both understanding the process and its practical operation.
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.
Dry grinding is used in some areas; however, it is confronted with problems and should be avoided except where absolutely necessary. Rod mills operate at lower speed than ball mills since the rods are rolled and not cascaded. For an equivalent grind, a rod mill uses less steel than a ball mill because of the lower speed and better contact ...
Rutherford Sales & Equipment, providing high quality new and used crushing equipment, grinding mills and mineral processing equipment for the mining and aggregate industry for four generations.
For re-election or magnetic separation equipment of tungsten-tin ore and other rare metal ores, to prevent damage caused by excessive grinding, a rod mill is often used. 2. When using a two-stage grinding process, if the first part is milled from 20-6mm to 3-1mm, the rod mill is used as the first part of the grinding equipment.
A rotating drum causes friction and attrition between steel rods and ore particles. The rods used in the mill, usually a high-carbon 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.
But it depends on the material you are mining for that will ultimately decide whether you should use a ball mill or a rod mill. A.M. King carries a wide selection of both and our un-used and pre-owned grinding equipment ready to use.
Semi-autogenous mills or SAG mills, as they are often called, can accomplish the same size reduction work as two or three stages of crushing and screening. Often used in grinding at modern mineral processing plants, SAG mills reduce the material directly to the desired final size or prepare it for the following grinding stages.
[citation needed] But note that the term 'rod mill' is also used as a synonym for a slitting mill, which makes rods of iron or other metal. Rod mills are less common than ball mills for grinding minerals. The rods used in the mill, usually a high-carbon steel, can vary in both the length and the diameter.
Open Circuit Rod Mill-Closed Circuit Ball Mill. This configuration has proven in the past to be a most reliable system due to the fact that rod mills are not particularly susceptible to variations in feed size. However, the necessity to procure grinding rods may limit the .

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. .
Apr 28, 2019· It is Widely used in refractory materials, chemical industry, metallurgy, glass and other industries on the grinding finished product uniformity requirements of high grinding .
Grinding Balls. Steel balls ranging from ¾ to 5 in. in diameter are used. Rods range from 1½ to 4 in. in diameter and should be 3 to 4 in. shorter than the inside mill length. Tube mills are usually fed balls smaller than 2 in., whereas 4- or 5-in. balls are more commonly used for ball-mill grinding.
