The rod mill uses steel bars as the grinding medium, and the materials are in point contact during the grinding process. Therefore, compared with the energysaving ball mill, the rod mill has the characteristics of uniform ore discharge, which is suitable for production lines that require more uniform particle size, such as the rod mill grinding quartz sand, sand making and other production lines.

Rod mills are less common than ball mills for grinding minerals. The rods used in the mill, usually a highcarbon steel, can vary in both the length and the diameter. However, the smaller the rods, the larger is the total surface area and hence, the greater the grinding efficiency. Principle of SAG Mill operation SAG mill. SAG is an acronym for ...

A ball mill operates more with the grinding surface action of the balls than the impact form of grinding that the rod mill uses. Taking this into account you can see that if the rod mill doesn't reduce the ore to a size that the ball mill can reduce quickly, the circuit load will climb until its volume is greater than can be handled.
