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
Rod mills are frequently used as primary mills to produce suitable feed to the second grinding stage Rod mills have usually a length diameter ratio of at least 1 4 Tube Mills Tube mills are in principle to be considered as ball mills the basic difference being that the length diameter ratio is greater 3—5

SAG mills are characterized by their large diameter and short length as compared to ball mills The inside of the mill is lined with lifting plates to lift the material inside the mill where it then falls off the plates onto the rest of the ore charge
Optimum choice of the make-up ball sizes for maximum throughput in tumbling ball mills ball-size ternary diagrams for various feed sizes with a circulation ratio of 2 5 at a size reduction ratio of 45 1 using a 1 m diameter ball mill It can be seen that maximum contour lines stay in the bottom of the diagrams for all cases indicating
The mill was expected to produce a product of 80 passing 150 μm The feed rate to the mill was 300 t h The ball mill grindability test at 65 mesh showed 12 kWh t The internal diameter of the ball mill was 5 03 m and the length-to-diameter ratio was 0 77 The steel balls occupied 18 of the mill The total load occupied 45 of the mill volume
The most recent published contribution on the topic of SAG mill aspect ratio dates to Morrell 2007 with his paper The effect of aspect ratio on the grinding efficiency of open and closed
