It is crucial to point out that shell protection is only one function of the mill liner. It also needs to optimise the grinding process. Clinker grain sizes depend on pre crusher settings but are in some cases still up to 50mm when fed to the ball mill and therefore, it is necessary to adjust the grinding tools accordingly.
