More DetailsBoth drive rolls have variable speed drives for operating the mill at the desired revolutions either wet grinding or dry grinding may be conducted in the batch ball and rod mills the jars should be charged with at least 20 pounds of balls or rods for the rod mill and 25to 40 by volume material to be ground 14 liters to 2 liters
More DetailsRod 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 between the media and ore the rod charge must be maintained in good working condition and broken and worn rods must be removed rod
More DetailsThe difference between ball mill and rod mill 1 shape and structure the ratio of tube length to diameter of the rod mill is generally 1520 and the inner surface of the lining plate on the end cover is vertical plane the ratio of cylinder length to diameter of ball mill is small and in most cases the ratio is only slightly greater than 1

More DetailsIn 1870 in the basics of the ball mill the trend was to develop a rod mill with a uniform distribution of the size of the blank in 1908 a selfball mill was developed without grinding media in the 40s and 60s of the 20th century the uk and france successively developed vertical shaft type medium speed coal mill s such as roller bowl coal
More DetailsBallrod mill literature the ballrod mills are meant for producing fine particle size reduction through attrition and compressive forces at the grain size level they are the most effective laboratory mills for batchwise rapid grinding of mediumhard to very hard samples down to finest particle sizes
More DetailsWhen the mill is rotated without feed or with very fine feed the rods are in parallel alignment and in contact with one another for their full length new feed entering at one end of the mill causes the rod charge to spread at that end this produces a series of wedge shaped slots tapering toward the discharge end the tumbling and rolling rods expend most of their crushing force on the
