The finesse of the material milled by the ball mill is 0.074mm-0.4mm, only except for the two small ball mills that have a wider range of 0.075-0.89mm. However, the rod mill fine grinding fineness is about 0.833-0.147mm. In terms of the fineness of the ground material, the ball mill has a finer handling ability.
These terms must not be confused with differential grinding, which has to do with the relative grinding rates of two or more minerals in an ore. …

For details, the grinding theory of ball mill and rod are different in many ways. For ball mill, the grinding force of steel ball to ore is less than the impact, because the contact area is small between balls and mineral. Thus, the throwing motion of ball can produce a large impact, but it need a high rotate speed and has a higher power ...

A rod mill is an ore grinding mechanism that uses a number of loose steel rods within a rotating drum to provide its attrition or grinding action. An ore charge is added to the drum, and as it rotates, friction between the tumbling rods breaks the ore down into finer particles. Although similar in operation, a rod mill is often more effective ...
HPGR wear vs conventional mills. Ball, SAG and rod mills all require their grinding media to be regularly replaced, unlike a HPGR. High Pressure Grinding Rolls have lower maintenance overheads than ball and rod mills, primarily because the grinding media in conventional mills needs to be replaced on a more regular basis.
The mill product can either be finished size ready for processing, or an intermediate size ready for final grinding in a rod mill, ball mill or pebble mill. AG/SAG mills can accomplish the same size reduction work as two or three stages of crushing and screening, a rod mill, and some or all of the work of a ball mill.
