discharge mill, e.g. see [23]. In industrial applications, the inner surface of the mill is lined with mill liners protecting the steel body of the mill and incorporating mill lifters which help to raise the content of the mill to greater heights before it drops and cascades down [36]. There are three types of grinding media that are commonly ...Web

In the circuit the dry solids of density 300 kg/m3 are fed at the rate of 25 tons/h. The feed to the cyclone contains 36 % solids by weight. As a result of a screen analysis, it is found that the proportions of the material finer than 250 micron in the rod mill discharge, cyclone feed and ball mill discharge is 27%, 14% and 5 % respectively.Web

The grinding performance of the latter ball mill was relatively poor and most of the coarse size fraction in the feed was present in the mill discharge. Figure 11 shows the feed and discharge size distribution of this ball mill, which demonstrates that approximately 15% of the mill discharge is composed of particles coarser than 4mm.Web
