Industry Reports
Ball Mill is different with Rod Mill
1. Grinding media of Rod mill are steel bars. ball mill use of steel balls as grinding media.
2. Rod mill is suitable for coarse grinding, when product granularity is between 1 to 3mm, processing capacity of rod mill is bigger than ball mill with same specification.
3. Rod mill has certain selective grinding effect because grinding media of rod mill and ores is in line contact. Hence, it has uniform product granularity and less over crushed ore grain.
4. Productivity of rod mill is generally about 15% lower than that of grid ball mill with same specification.when product granularity is smaller than 0.5mm, grinding effect of rod mill is not as good as ball mill with same specification.
5. Feeding granularity of rod mill is generally 15 to 25mm. product granularity of rod mill can be up to 1~3mm.
