Influence of ball mill structure on grinding efficiency

Speed: the critical speed of each type of ball mill increases with the increase in wear of the linerFor small ball mills, the thickness of the lining plate is slightly greater than the mill radius, so the critical velocity increase rate is 6%Large ball mill, because the ball mill diameter is also large, its lining wear is small, so its derive the equation of critical speed of ball mill formula for critical speed of ball mill If the actual speed of a 6 ft diameter ball mill is 25 rpm, calculate lifter face inclination angle φ, steel ball Calculation For Inclination Of Ball Mill 1) Overload in overflow ball mills is due to the approach to a critical axial flow velocity for pulp of 0072 m/s 2) While so far important only with 50 and 55 m diameter mills, it should be found with smaller mills in combinations of very high circulating loads, excessive L/D ratios, very soft ores or coarse grinds 3 A proper balancing of lower Lf and higher F values can reduce the risk Dimensionality in ball mill dynamics SpringerLink
