Figure 5. High–low wave ball mill liner Materials The selection of the material of construction is a function of the application, abrasivity of ore, size of mill, corrosion environment, size of balls, mill speed, etc. liner design and material of construction are integral and cannot be chosen in isolation.
If a ball mill uses little or no water during grinding, it is a 'dry' mill. If a ball mill uses water during grinding, it is a 'wet' mill. A typical ball mill will have a drum length that is 1 or 1.5 times the drum diameter. Ball mills with a drum length to diameter ratio greater than 1.5 are referred to as tube mills.

For ball mills, wear and tear of the lifting bars is the main causes of failure of the liner of the ball mill. According to historical data, wet ball mills consumed more than 110,000 tons of liners in metal mines during 2004 in China. However, green environmental protection is the mainstream trend of world economic development, which adds new ...
A ball mill and a tumbling mill are both types of grinding mills used to reduce material size. We mainly use a ball mill for mixing and grinding processes. In contrast, we generally use a tumbling mill for finer material reduction. What are the balls? Ball mills grind materials into an extremely fine form.
