"Elongation is how far a bolt stretches when tightened and is the only true indication of load" When a mill is commissioned, the construction company should make sure that all the bolts are tightened to the correct load / torque to keep the flange joint tight and together during operation. This load should be checked and verified.

The relaxation on liners is particularly high, the mating surfaces between the lifters, liner bolts and liner plates are roughcast and tapered. Any small embedment of high spots will be multiplied by the slope angle. By way of an example, if 0.1mm embedment occurs on a 1:4 taper that will result in 0.4mm in lost elongation.

This concept is similar to preloading bolts when assembling a mill. When you tighten the bolts, you compress the flanges (i.e. the clamped parts), and when the mill is running, any additional load on the joint will be partially distributed to further stretch the bolt, and partially to relax the joint.
