Such mills are common in South African operations; mills are sometimes referred to as tube mills or ROM ball mills and are also operated both autogenously and semiautogenously. Many of these mills operate at higher mill speeds (nominally 90% of critical speed) and often use "grid" liners to form an autogenous liner surface. These mills typically grind ROM ore in a single stage. A large ...

a) Mill Geometry and Speed – Bond (1954) observed grinding efficiency to be a function of ball mill diameter, and established empirical relationships for recommended media size and mill speed that take this factor into account. As well, mills with different length to diameter ratios for a given power rating will yield different material retention times, the longer units being utilized for ...

and ball mills, have almost become obsolete in the move to higher milling rates required to process lower metal grades. Grinding circuits with fully autogenous (AG) or semiautogenous (SAG) mills, often combined with ball mills are now the standard to meet the high capacity requirement for processing ores with lower metal grades. Simulation software and powerbased equation methodologies have ...

a mill grindout (no ore feed) of 10 to 20 minutes is also performed before mill inspection or relining. The complete grindout is required to obtain the accurate ball load measurement or the percentage by volume of balls in the mill. This is usually performed soon after a crash stop. The basic principle is to measure the height ''H'' from the charge to the shell and the internal mill ...
