However, the actual amount required for a particular ore would probably be different. For example, in a sulfide concentrator, addition of lime to the pyrrhotite regrind mill reduced ball consumption by 40%. The lime was added at kg/t of ore which changed the feed pH = to discharge pH = Composite Materials for Ball Mill Liners

Introduction. Ball milling is generally known as a method to mix, blend, shape and reduce particle sizes. It can also be used as a mechanical synthesis method to produce materials that are milled to extremely fine powders. Several factors, like milling temperature, type of mill, milling speed etc. need to be considered when using ball milling ...

The ball mill has higher circulation load, it generates only 30 35% of actual fines you require to be called as product. If your product size needed is passing 45 micron, then the ball mill total discharge material will contain normally 30% of 45 micron. The rest is oversize which has to be ground again.
