In Grinding, selecting (calculate) the correct or optimum ball size that allows for the best and optimum/ideal or target grind size to be achieved by your ball mill is an important thing for a Mineral Processing Engineer AKA Metallurgist to do. Often, the ball used in ball mills is oversize "just in case". Well, this safety factor can cost you much in recovery and/or mill …
As different ball mill machines grind different sizes, ball mills generally produce p100 size. According to how the material is discharged, ball mills can be divided into overfall and grate types. And they have different properties and advantages. There are many types of grinding media suitable for use in ball mills.
More crushing and less grinding to reduce the grinding particle size; If the grinding particle size is large, the mill needs to perform more work on the ore. In order to achieve the required grinding fineness, the workload of the ball mill is bound to increase, so energy consumption and power consumption will also increase.

Answer (1 of 2): there are many different grinding mill can be used in barite and limestone powder processing, ball mill, Raymond mill, ultra fine mill and so on. the Moh's hareness of barite is about 3–3.5, and the limestone is 3. so there is no any difference between barite grinding mill and li...
Grinding Particle Size. Due to the relatively high operating costs in grinding stage, most plants often use ball mills for grinding operations after fine crushing. The particle size of the ground material is relatively fine, the feeding particle size is usually in the range of 10-20mm, and the product particle size is usually in the range of 0 ...

The size distribution produced by the ball milling of various crystalline and non-crystalline materials, showed that initially there was a fairly even distribution over the size range up to 355μm. However, as milling proceeded two distribution modes developed; one at about 90μm (the persistent mode) and one at about 250μm (the transitory mode).

For this coarser feed the 50 + 20+10 mm ball diameter mix breaks the material at a faster rate compared to the other ball matches. The availability of a ball size for a particular feed size ensures breakage occurs at a faster rate. The 10 mm ball size is unable to nip the large particle size hence the breakage rate is slower.
