Holes for bolting are offset from the cross-section axis and located at the base of end projections to rotation direction of the drum.

Industrial operation of the liner showed that the decrease of in direct influence of ore-ball mixture into holes increases liner service life by 1.2 ... 1.3 times; mirror execution of the each subsequent liners row, located in the annular row of the drum and promotes intensification of grinding process.

The positive effect of the introduction of technology is reduced the grinding process duration and long service life of the liner.
