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 ...

The grinding mill's production capacity is generally calculated based on the newly generated powder ore of less than mm (200 mesh). It is calculated by multiplying the unit productivity (q'm) by the new generation grade (), and the result is expressed as t/ (m3. h). The ball mill operates by rotating a cylindrical shell about its ...

As in ball mills, the power draft of a rod mill is the product of capacity and work index, which is the energy required to break a mineral of a given size to the required size. The mill power is also increased by increasing the rod charge and the mill speed, while the mill power and capacity are both increased with increasing mill length.

The vibrating ball mill also works on the principle of attrition and impact. It consists of a mill shell containing a charge of balls similar to that of ball mills. In this case, the shell vibrates due to some frequency rather than rotated. Uses (i) Small capacity ball mills are used for the final grinding of drugs or for grinding suspensions.
