Ball Mills - Mineral Processing & Metallurgy

Ball-Rod Mills, based on 4″ liners and capacity varying as 2.6 power of mill diameter, on the 5′ size give 20 per cent increased capacity; on the 4′ size, 25 per cent; and on the 3′ size, 28 per cent. This fact should be carefully kept in mind when determining the capacity of a Steel- Head Ball-Rod Mill, as this unit can carry a greater ...

What is the difference between vertical mill and ball mill?

5. Lower initial cost. The initial construction cost, running cost and maintenance cost of the vertical mill are only 70%~80% of the ball mill equipment. 6. The particle size of the grinding material is large, which can reach 3%-5% of the diameter of the grinding roller. The large-scale grinding allows the material to have a large particle size.
