Results also showed that the size reduction of the silicates increased with an increase in mill solids and ball filling degree. For chromite the mill solids did not appear to have any effect at low ball fillings but a slight shift was observed at the higher ball fillings tested.
SAG mill 3.8 MW and a 15 ft. diameter ball mill 3.5 MW. Cyclone overflow OF is sent downstream for gold leaching. Following sampling the SAG mill was crash stopped and the total load measured. The SAG mill ball load was also measured following a grind outafter the first survey.
Sep 01 2016 In one of the PGM plant surveys the ball mill feed F 80 size was 17.8 mm and the ball mill product P 80 size was 0.19 mm achieving a size reduction ratio of 94 in one stage grinding. A very long residence time is required for the slurry to be retained in the mill for sufficient size reduction but at a cost of reduced mill productivity.

Size Reduction in Mining Industries with Ball Mill With the grinding process known as a common and old method the complex ore is brought to the desired size. Thus it is the important step in benefication processes in the mining industry in terms of efficiency increase in leaching processes.
Starting size is 1 meter in two-three stages the material can be crushed down to 1 mm particle size. Crushing is followed by grinding and it is quite common to use nowadays two grinding stages in a semi-autogenous – ball mill circuit SABC. The size reduction ratio in
The SAG mill circuit also includes a single-deck screen and a cone crusher while the ball mill circuit utilizes hydrocyclones. Currently the grinding circuits are inefficient in achieving the aspired product fineness of xP80 125 μm even at low to normal throughputs 450-600 th.
When grinding or blending materials you need a mill that will give you a fast and even distribution of the milled sample. Essa laboratory ball and rod mills achieve excellent size reduction no matter what your application. Use them to mill and grind soft hard brittle and fibrous materials either in a wet or dry state.
