The length of the cylindrical shell is usually 1–1.5 times the shell diameter (Figure 8.11). The feed can be dry, with less than 3% moisture to minimize ball coating, or slurry containing 20–40% water by weight.A guide to maximising ball mill circuit classification,,case studies will illustrate the gains in ball mill circuit efficiency that can be achieved by maximising CSE. INTRODUCTION The importance of classification to ball mill circuit efficiency has been studied and emphasized by many comminution experts through the decades (Bradley, Davis, Heiskanen, Hukki, Jankovic, McIvor ). The slurryBall Mill Application and Design - Paul O. Abbe,Ball mills cab be used equally well for wet or dry grinding. In the case of wet grinding the particles are also dispersed in the liquid medium. For temperature sensitive products, ball mills can be fully jacketed to maintain temperatures of the product. Ball mills scale up well and in fact improve in performed with increasing size. Ball mills,
