grinding rods for rod mill

Rod Mills Mineral Processing & Metallurgy

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.get price

Effect on Rod Mill Power DrawEffect on Rod Mill Power EfficiencyPractical Rod Mill OperationThe general relationship between mill power draw and charge level is as shown in Figure 2. As previously discussed, the exact shape of this curve, and the position of the peak, may vary slightly for each particular mill, and depend- on the liner condition.As pointed out by Bond and Rowland, the overall density of the charge may be reduced by the presence of broken rod pieces, and this tendency will be increased with use of larger mills and larSee more on 911metallurgist

Rod Mill an overview ScienceDirect Topics

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.get price

Grinding Balls & Rods Mineral Processing & Metallurgy

The original charge to a mill is generally between 40% and 50% of mill volume for ball mills and 35% to 45% mill volume for rod mills. As a general figure rod mills will have a void space within the charge of around 20% to 22% for new rods. In ball mills the theoretical void space is around 42% to 43%. It has been found that as grinding rodsget price
