Using a comminution kinetics equation and a classification efficiency equation, a simulation of closed- circuit grinding was carried out under the condition that the fineness is expressed by the sieving mass ratio.<BR>The higher the efficiency of classification, the more the production rate increases. Also, the powder passing rate through the mill, which is indicative of the maximum production rate, shifts to a higher value as classification efficiency increases. The parameters <I>k</I> and <I>n</I> have a specific relation under the usual condition of cement grinding. In this condition, the production rate increases with a decrease in the parameter <I>n</I> under 20-30 μm of the over size ratio 19 % particle diameter. But it increases with an increase in the parameter <I>n</I> over the diameter.
