Ball Mills vs Rod Mills. 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.
Rod Mills are similar with the Ball Mills xcept 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 accept feed up to about 50 mm ...

We will begin with the mill's bull gear assembly and work towards the motor, The BULL GEAR, sometimes called the RING GEAR is designed to turn the mill transforming the energy of the motor into motion for the mill. By mill we refer to Ball Mills, Rod Mills and SAG Mills. Anything gear and pinion really.
Ball mills can be operated in a wet or dry state, depending on the application. Rod Mills. Rod mills are similar to ball mills, but instead of using grinding balls, they use long steel rods to do the grinding. The rods grind the ore by tumbling within the mill, similar to the grinding balls in a ball mill. Autogenous Mills
To illustrate the characteristics of various type mills we have shown the types of discharge for rod mills and ball mills. There are essentially four types of rod mill discharge: the overflow type; ... Then take a similar sample but this time grind for a few minutes and screen at 65-mesh removing the finished material, then return the oversize ...
Unlike ball mills, rod mills use long steel rods instead of balls as the grinding medium. Rod mills are ideal for breaking down materials such as minerals and ores. In this article, …

If a ball mill uses little or no water during grinding, it is a 'dry' mill. If a ball mill uses water during grinding, it is a 'wet' mill. A typical ball mill will have a drum length that is 1 or 1.5 times the drum diameter. Ball mills with a drum length to diameter ratio greater than 1.5 are referred to as tube mills.
Effect of mill speed on material holdup: Figure 10 shows the material holdup as a function of mill speed for both rod and ball mills. As can be seen from the results given in this figure, the holdup in the ball mill at all speeds is lower than the corresponding holdup in the rod mill under similar operating conditions.
Ball Mills Steel Ball Mills & Lined Ball Mills. Particle size reduction of materials in a ball mill with the presence of metallic balls or other media dates back to the late 1800's. The basic construction of a ball mill is a cylindrical container with journals at its axis.
Ball mills vary greatly in size, from large industrial ball mills measuring more than 25 ft. in diameter to small mills used for sample preparation in laboratories. Rod mills are similar to ball mills and use metal rods as the grinding media. Pebble mills use rock pebbles as the grinding media to cause friction and attrition between the pebbles ...
