This tool, according to RME, is suitable for larger mills. Each unit requires a Thunderbolt Power Pack to supply the electrical and hydraulic needs of the hammer and powered suspension options. The hammer can operate with any standard threephase supply (380, 415, 480, 525, 575 or 600 volts at 50 or 60 Hz).

The resulting angularity deviation between the liner bolt pocket and bolt creates two highstress points of contact. This poor interface becomes an issue the moment the mill goes into service, eventually causing premature failure that can require a total shutdown in order to tighten loose bolts or replace broken liners. Valley Forge Bolt has ...

Ball mill Most ball mills, even in primary applications, have a finer ore feed size; this requires some impact but not enough to increase the media consumption or even break the liners. Typically, a ball mill lining has a more rounded profile, often like a sine wave, and the size of the waves is selected based on the size of grinding media used.

All liner bolt cuts should be firmly tightened by use of a pipe extension on a wrench, or better yet, by use of a torque wrench. The bolt heads should be driven firmly into the bolt holes with a hammer. In order to minimise the effect of pulp race, we recommend that the spaces between the ends of the shell liners and the head liners or grates ...

Based on experience, millliner designs have moved toward more openshell lifter spacing, increased pulp lifter volumetric capacity, and a grate design to facilitate maximizing both pebblecrushing circuit utilization and SAG mill capacity. As a guideline, mill throughput is maximized with shell lifters between ratios of :1 and :1.

3 Common causes of bolt failure. Most mill operators are familiar with (and regularly go through) a process known as retorque. Retorque is an expensive exercise resulting in lost production, but is believed to be necessary in order to avoid bolt failures that cause unplanned shutdowns. It doesn't have to be this way however, by eliminating ...

There are basically two groups of Grinding Mill Liners. Ones with a HIGH PROFILE and those with a LOW PROFILE. The high profile liner is designed to give the media the higher lift. This type will be used in mills that are designed for primary grinding and as a result require the impact of the higher cascade. Ball mills working as the secondary ...

RME BOLTBOSS is an integrated technology toolset that allows SAG, AG and ball mill liner bolts to be secured from outside the mill during new liner placement. The system enables safer liner installation by eliminating the need for reline crew to be on the mill charge and in the vicinity of mill relining machine (MRM) movements during liner placement.

High Relaxation. 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 embedment occurs on a 1:4 taper that will result in in lost elongation.
