One of the advantages of a rod mill is that it can handle a higher capacity than a ball mill of the same size. Additionally, the grinding medium in a rod mill is more uniform than that in a ball mill, and this can be beneficial for certain materials. Rod mills are also relatively lowmaintenance, making them a costeffective option for many ...
