The grinding medium then started tossing as a result. Impact, attrition, and abrasion are created during grinding because of the free movement of unconnected media like ceramic balls, coarse ore pebbles, or steel rods. Ball mills work well for finer grinding, whereas rod mills can handle coarse grinding.

The PRRK-series is often used for dry grinding in rod mills, and in certain ball mill applications. ... When choosing primary autogenous grinding, run of mine ore up to 200-300 mm in size is fed to the mill. When using a crushing step before the grinding, the crusher setting should be 150-200 mm. The feed trunnion opening must be large …
The maximum particle size of the lump ore fed into autogenous mill is 300–350 mm. In the grinding mill, the ore blocks sized >100 mm function as grinding medium. The ore particles smaller than 80 mm but bigger than 20 mm have poor grindability and they cannot be easily ground by big lump ore, so such material is …
Center Periphery Discharging Rod Mill.

Rod mill gets its name because its grinding body inside the barrel is steel bar. Rod grinding mill, as first-class ore grinding machine, is widely used in the first class grinding in industries such as artificial sand, ore beneficiation plant and power sector in chemical plant. Rod grinding mill is also called rod mill or grinding rod mill.
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 …
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. Rod Mills = Selective …
The rod mill grinds the ore by the pressure and peeling force of the grinding media. The bar first breaks up the coarse particles and then grinds the smaller ones. …
