2.3 Quantity ofloading medium.Ball loadingcapacity The volume of thegrinding mediumis the percentage of the effective volume of themill, which is called the filling rate of thegrinding medium. The size of filling directly affects the number of shocks, the area ofgrindingand theloadofgrinding mediumin thegrindingprocess.

The starting point forball mill mediaand solids charging generally starts as follows: 50%media charge. Assuming 26% void space between sphericalballs(non-spherical, irregularly shaped and mixed-sizemediawill increase or decrease the free space) 50% x 26% = 13% free space.

Ball Mill Power CalculationExample #1. Awet grinding ball millin closed circuit is to be fed 100 TPH of a material with a work index of 15 and a size distribution of 80% passing ¼ inch (6350 microns). The required product size distribution is to be 80% passing 100 mesh (149 microns). In order to determine thepower requirement, the steps are as follows:

For example your ball mill is in closed circuit with a set of cyclones. The grinding mill receives crushed ore feed. The pulp densities around your cyclone are sampled and known over an 8-hour shift, allowing to calculate corresponding to circulating load ratios and circulating load tonnage on tons/day or tons/hour. This is %Solids/Densities Based Circulating Load Calculation Method obtained from the pulp/slurry …

Jul 01, 2003· This is achieved by changing thegrinding media, process milling method or using a more efficientmill. The specific energy requirement is the best parameter for choosing the most efficientmill. Themillthat works at the lowest specific energy will save you the most time and money over the life of …
