Rod Mills. In contrast to ball mills, rod mills employ long rods as the grinding medium. Similar to grinding balls in a ball mill, the rods tumble inside the mill to grind materials like limestone or various ores. The lengthtodiameter ratio is kept between and to avoid circumstances that might result in rod charge tangling.

Introduction Rod Mill Used as the primary comminution unit in a grinding circuit. Rods are placed parallel along the length of the rod mill. Rods are 150mm shorter than the mill length. Breakage occurs more from cascading than cateracting. The product size distribution is narrower than a ball mill but significantly coarser.

Crushed ore is fed to the ball mill through the inlet; a scoop (small screw conveyor) ensures the feed is constant. For both wet and dry ball mills, the ball mill is charged to approximately 33% with balls (range 3045%). Pulp (crushed ore and water) fills another 15% of the drum's volume so that the total volume of the drum is 50% charged.
