AG/SAG mills can accomplish the same size reduction work as two or three stages of crushing and screening, a rod mill, and some or all of the work of a ball mill.
The Overflow ball mills discharging speed is lower than that of grid ball mills. As a consequence, the capacity of the former is smaller than that of the latter, about 10% to 15%. The tendency of Overgrinding. In overflow ball mills, the ores stay longer so it is easy to appear over-grinding phenomenon. However, grid ball mills do not.Fruitful Ball Mills,Ball mills designed for long life and minimum maintenance not be limited to: grate discharge, peripheral discharge, dry grinding, special length to diameter ratio, high A ball mill grinds ores and other materials to a typical product size of 35 mesh or finer.
Overflow Versus Grate Discharge Ball Mills: An Experimental Investigation It has been widely accepted to go for grate discharge ball milling when a coarse product is preferred or to avoid production of extreme fines, but overflow discharge mills are preferred for their simplicity of design and production of finer product.Improved Relationships for Discharge in SAG/AG Mills,there has been a shift of emphasis on ball mill optimization to semi-autogenous grinding (SAG) mills. In order to optimize this section, the skills to accurately model and filling in the mill and not related to total mill filling. Discharge through an individual opening on the grate is driven by the factors of ore filling, radial position
