2019-12-30 The rod mill usually uses 50-100mm diameter steel rod as grinding medium, while the ball mill uses steel ball as grinding medium. The length of steel rod is 25-50mm shorter than the cylinder, and it is usually made of high carbon steel with carbon content of 0.8% 1%; the loading capacity of rod is about 35% 45% of the effective volume of rod mill.
Rod Mill an overview ScienceDirect Topics
As such, when the product is sticky, rod mills are preferred over ball mills. Rod mills have an industrial yield that is less than that of a ball mill, which explains the fact that balls have a much larger grinding surface than rods. The power needed to operate a rod mill could exceed 30% of the power used in a ball mill.
Flow of materials in rod mills as compared to ball mills
2012-1-25 As mentioned above, the difference in the material flow behavior between the ball mill and the rod mill partially explains the well known difference in the product particle size distribution of ball mills and rod mills. In the case of ball mills, the axial dispersion is higher and the mean residence time is shorter than those in rod mills. In rod mills, the axial dispersion is lower—close to plug flow (Lynch, 1977)—as well as selective breakage (compared with ball mills)
