They can accomplish the same size reduction work as two or three stages of crushing and screening, a rod mill and some or all of the work done by a ball mill. SAG mills are also an optimum solution for wet grinding since crushing and screening in these cases can be difficult, if not impossible. Efficiency through automatic operation

Steel slag solution rod mill grinding body grinding rod diameter 130/140/150mm grinding rod advantages Now many steel slag grinding has replaced the original 120mm diameter steel rod with a 130-150mmmm steel rod, and even plans to use 200mm. Why? More broken and less grinding .
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.
The mill diameter, low or high ratio of reduction, and oversize feed factors also must be applied to the calculated grinding power. When calculating rod mill power for a rod mill-ball mill circuit, do not allow for improvement in the ball mill performance due to receiving rod mill feed.
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. However, the smaller the rods, the larger is the total surface area and hence, the greater the grinding efficiency. Autogenous mill ...

The first two Grinding Efficiency Measurement examples are given to show how to calculate Wio and Wioc for single stage ball mills. Figure 1. The first example is a comparison of two parallel mills from a daily operating report. Mill size 5.03m x 6.1m (16.5′ x 20′ with a ID of 16′). This example shows that Mill 2 is slightly more efficient than Mill 1 even though it has a higher power ...
The IsaMill is a stirred-medium grinding mill, in which the grinding medium and the ore being ground are stirred rather than being subjected to the tumbling action of older high-throughput mills (such as ball mills and rod mills). Stirred mills often consist of stirrers mounted on a rotating shaft located along the central axis of the mill.
Alibaba offers 189 high efficiency grinding rod products. About 1% of these are mining machinery parts. A wide variety of high efficiency grinding rod options are available to you, such as free samples.
Rod mills rod mills are used in both wet or dry applications for a wide range of materials. Using rod as grinding media, these mills produce a uniform sized product while minimizing unwanted fines. Replace up to 3 stages of crushing and screening Mill motor power up to 26,850 kW Grind ore to 35 mesh or lower Feed sizes up to 20 mm
The grinding medium test shows that the spherical and long rod medium grinding effect is the best. The collision of spherical medium is point contact during grinding, so the ball milling efficiency is high and it is easy to grind fine, but compared with rod grinding, the phenomenon of over grinding is serious. When the grain size of ore feeding ...

Rod mills are very similar to ball mills, except they use long rods for grinding media. The rods grind the ore by tumbling within the the mill, similar to the grinding balls in a ball mill. To prevent the conditions leading to rod charge tangling, the length to diameter ratio is maintained at 1.4 to 1.6.
