    Ball Mills vs Rod Mills

    2021-5-4  The average particle is subjected to an action similar to many sets of rolls in series, before it is discharged. 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 get price

    Rod Mills, How Do They Work? Mine Engineer.Com

    2012-11-26  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 get price

    Rod Mill an overview ScienceDirect Topics

    Rod mills are used in an open circuit between crushing and the ball mill. They often operate in wet and where the pulp contains up to 50% solid by mass. This machine is equally very applicable to dry where it could take a feed that has achieved 6% moisture. As such, when the product is sticky, rod mills are preferred over ball mills.get price

    Ball Mills an overview ScienceDirect Topics

    Ball Mills. Ball mills have been used for the preparation of coal–oil and conventional coal–water slurry fuels, also in large sizes up to a capacity of 50 tonnes of coal per hour (Austin et al., 1984).

    HOW BALL MILL WORKS? energosteel

    Drum Liners of ball mills operated on a large source material have ribs. For mills operated on the fine materials use lining with small ribs or quite smooth. Height, mutual arrangement and shape of the ribs define force of adhesion the grinding media with the drum and the results of the mill’s work.get price

    How HPGRs compare to conventional milling

    As a result, ball mills produce a rather wide particle-size distribution (PSD), requiring additional work downstream, while rod mills achieve a lower PSD but produce a coarser product. By comparison the inter-particle compression in a High Pressure Grinding Roll has a more even effect on the entire feed, resulting in a high ratio of finesget price
