Effect of Pulp Density on Selective Grinding. In Fig. 6.4 are plotted curves, again according to Coghill and Devaney, which show the effect of pulp density upon selective grinding and it is at once evident that a more rapid reduction of the larger fractions is obtained with a pulp of moderate thickness than with a very thick one. The probable explanation of this phenomenon is that with a fluid ...
