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). With the advent in the eighties of larger and larger SAG mills running in single ...
