Ball Mill Critical Speed [1d47v91w6y42]
ABSTRACT: In this study, the effect of fraction of mill critical speed was investigated on the limestone and the clinker samples using Göltaş cement factory (Isparta/Turkey) at batch grinding conditions based on a kinetic model. For this purpose, firstly, six different mono-size fractions were carried out between 0.850 mm and 0.106 mm formed by a V2 sieve series. Then, S, and BM equations

Ball Mill Critical Speed. A Ball Mill Critical Speed (actually ball, rod, AG or SAG) is the speed at which the centrifugal forces equal gravitational forces at the mill shell’s inside surface and no balls will fall from its position onto the shell. The imagery below helps explain what goes on inside a mill as speed varies. Use our online formula.
