Improving the liner design and material could also improve the grinding efficiency while enhancing the life of the liners. As illustrated by the dashed line in Fig. 2, the optimum throughput could correspond to less frequent relining (e.g. 2 relines per 6 months) which will introduce additional benefits.. Lacking both the data and tools for determining the efficiency of relining for the shell ...
