SAG Mill Shell Liners Spacing Grinding & Classification
Don't you use a layer of rubber behind the liners to protect the shell? Here for steel liners in a SAG mill, 10 to 15 mm (1/2 inch) Here on primary mills the liners aren't in there long enough to need filling in the gaps and I can't imagine any filler material that would last anyway The gaps fill with ball chipsEnd and shell liner design in these mills is much the same as for SAG mills The effect of liner design on performance is equally as important For instance, in an iron ore operation using 64 m (21 ft) mills, mill throughput was increased by 15 percent and power consumption reduced bySAG Mill Liner Design Mineral Processing & Metallurgy
