The coal mill grinding system is an important part of the dry process cement manufacturing. In cement plants, we usually adopt the air swept coal mill system or vertical mill system as the pulverized coal preparation system, which is arranged at the cement kiln head or kiln tail to provide fuel for clinker calcination. However, due to the flammable and explosive characteristics of pulverized ...

and charge. After all, it is the interface between the mill and the grinding charge. Although work on the grinding action in mills was published 100 years ago (White 1905 and Davis 1919), the first publication on the influence of liner design on the charge motion only appeared in 70 years later (McIvor 1983).
