To prevent most conditions leading to rod charge tangling, the generally recommended relationship of rod length to mill diameter Inside liners is 1.4 to 1.6. When this ratio becomes less than 1.25 the risk of tangling Increases rapidly. For rod mills larger than 3.8 meters (12.5 feet) in diameter rod availability.

Rod Mills - Mining Technology | TechnoMineNov 26, 2007 . The mill length is limited by manufacturing constraints for the grinding rods. Rod mills are typically used for grinding ores, coal/coke, and other materials for both wet and dry applications. Length-to-diameter ratios should be kept above 1.4 to prevent rod entanglement. In general, rod mills create a coarser.length to diameter ratios rod mill,Mill (grinding) - WikipediaBall mills normally operate with an approximate ball charge of 30%. Ball mills are characterized by their smaller (comparatively) diameter and longer length, and often have a length 1.5 to 2.5 times the diameter. The feed is at one end of the cylinder and the discharge is at the other. Ball mills are commonly used in the.
