According to production experience, we can follow the below principles to match different ball sizes for ball mill: (1) Based on grain size, hardness, material grindability and the product fineness requirements, we can determine ball gradation. When material grain size is small and fineness requirement high, we need to choose small size steel ...

Several laboratory

and required product size. It is then possible to determine the size of mill required based on throughput, and therefore motor power. The standard Bond Ball Mill Work Index test procedure is firstly to stage crush the feed to minus 3.35mm, and size a representative sample. The test then involves a series of batch grinds in a standard Bond mill.
