When 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
Ball mill and rod mill are the common grinding equipment widely used in the mineral processing plant. They are similar in shape and grinding principle, but also different in structure, performance and application. Here are seven differences between ball mill and rod mill to tell you how to choose the ball mill and rod mill.
Recommendation of ball mill and rod mill Ball mill and rod mill are suitable for different materials 1. Selection by material's hardness Ball mill has a strong adaptation of material, and it is suitable for grinding hard materials, such as slag, iron ore, copper ore, etc. Rod mill is suitable for grinding brittle material, such as rare metals.
Rod 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 ing condition, and broken and worn rods must be removed.
The difference between ball mill and rod mill . 1. Shape and structure. The ratio of tube length to diameter of the rod mill is generally 1.5-2.0, 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.
Sep 09, 2019· The milling equipment which are widely used in the mineral processing plant are the ball mills and the rod mills. The two have similarities in shape and grinding principle, but there are also differences in structure, performance, use and so on. First, when the barrel rotating, the grinding medium (ball or rod) installed in the
Comparison between Rod Mill and Ball Mill. 2014-01-03. Rod mill is a type of grinding mill whose grinding media is steel bar, while ball mill is steel ball. 1. Rod mill are usually applied to grinding the w-sn ore and rare metal in the reselection or magneticore-dressing plant in order to avoid the damage caused by the over crushing.

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.
