Five sets of the industrial ball milling survey data were used to validate the ball mill model. The data were acquired from four full scale ball mills covering primary and secondary grinding duties in a gold concentrator and a PGM concentrator. In all cases, the model fits the ball mill operational data well.
The investigation was limited to wet grinding overflow discharge ball mills, as the majority of operational ball mills are of this type. In a grinding mill, particles …

A 3 × 3 m wet overflow ball mill in open circuit was charged with 38 t of grinding media in the form of 101 mm diameter balls at a density of 7.9 t/m 3. The mill rotated at 21 rpm. The bed porosity of the material to be ground was 35% and the work index of the material 13.7 kWh/t (wet grinding). The feed size was 80% passing 2.0 mm …
Axial slurry transport and mixing in a wet overflow industrial scale ball mill (modelled using fully coupled DEM and SPH) 3. Effect of mill speed on slurry and solid charge motion and the resulting grinding of fine particles in a 1.8 m diameter wet Hardinge pilot mill (modelled using fully coupled DEM and SPH with advection-diffusion …
The main component of wet overflow ball mill is a cylinder with bigger diameter and smaller length which is revolved by transmitting machinery. Materials are put in cylinder through the feed opening and then thoroughly grinded. The falling course of iron balls and ores can produce huge falling impact and autogenous grinding.
6. Overflow Ball Mill. An overflow ball mill is a type of ball mill where the material to be ground is discharged through the overflow at the end of the mill. The overflow …
The following equation is used to determine the power that wet grinding overflow ball mills should draw. For mills larger than 3.3 meters (10 feet) diameter inside liners, the top size of the balls used affects the power drawn by the mill. This is called the ball size factor S.
