Chapter Iii - SlideShare. 3. Ball Mills They are rotating cylindrical or conical steel chambers, approx. half full (20 -50% volume) of steel or iron balls or flint stones They can process coal, peels or feldspar.
The Conical Mill is believed to boost the efficiency of grinding by 2.7 times. The mill works on a principle of automatic segregation of balls by size which allows for continuous grinding with no need for chambers.
It has been found that a change in density of 2.6 to 2.9 (an increase of density of 11.5%) gives a 1.5% increase in mill power for these conical mills, for Pb = 7.75. Inserting p51 = 2.6, Pb = 7.75 and solving for fc gives 0.445, and using the estimate for c, f ~ 1.0. Thus it appears that the powder in the mill is circulating in about the same ...
