SAG Mill Liner Packing
Packing will result if the gaps between the liners permit it, and if the particle size produced in the mill will fit in these gaps. We see packing in our dry vertical roller mills and also in cement mills. Granted the packing is not as severe as in wet mills, as the presence of water can cause some ores to behave like a self-setting concrete mix.
