Mill Bolting

The mill manufacturer specifies a load which is designed to be the optimum load applied to the bolts to hold the mill together for its entire life, which can be in excess of 20 years, some mill manufacturers specify an elongation, unfortunately they usually specify a torque figure which should in a best case produce the correct elongation, but ...

SAG - Molycop

After removing the nut, the moil is inserted into the bolt end. Without the need to remove recessed or seal washers the bolt can be driven out of the liner and completely clear of the mill shell in one movement. Recent trials at a large copper concentrator have shown that bolt removal time was halved by using Easy-Out Bolts.

Leaking Mill Shell Bolts

Dealing with leaking Mill Shell bolts is common enough an occurrence in most concentrator plants. All that an operator can really do about it is to keep the problem to a minimum. The cause of the bolts leaking is running the mill with a density that is to light or feed that requires a high impact to grind. This could either be due to hard or large ore. “Leakers” are common on SAG and AG ...

Semi-autogenous grinding (SAG) mill liner design and ...

In recent years, the trend in large SAG mills has been to use wide-spaced shell lifters with large lifter face angles, primarily to reduce packing and ball/liner damage, and to use larger, hence fewer, mill liner parts to reduce downtime at liner change-outs.
