Ball mill is a kind of equipment with high energy consumption. During operation, all parts of the ball mill are in motion, with large vibration and high energy consumption; Compared with the ball mill, the vertical mill can save 30% 40% of energy consumption, and has low vibration, which is a low energy consumption.
The Difference Between the Ball Mill and Rod Mill. 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 ...
ball mill vs vertical roller mill . Similar to the ring and ball mill the vertical spindle roller mill uses large quot tires quot to crush the coal These mills are usually found in utility plants Raw coal is gravity fed through a central feed pipe to the grinding table where it flows outwardly by centrifugal action and is ground between the rollers and table

Nevertheless, ball mills can be a more appropriate choice for grinding larger sized material starting at 1/4 " or larger. It should be noted that ball mills are much larger than Attritors and therefore require a special foundation. The Attritor''s design accounts for much of the difference: conventional ball mills turn the entire drum or ...
It can be seen from the experimental results that from the perspective of crushing efficiency and particle size distribution, the vibratory milling process is better than the ball milling process, and the bead milling process is significantly better than the ball milling and vibrating milling processes.
To calculate a ball mill''s critical speed use the following equation: For the mill speed of RPM, means that this ball is running at ( ÷ ) X 100 = 75 % of its critical speed. Bear in mind that feed material type, ball volume loading, ball charge gradation and liner types can also affect the grinding conditions as well.
