Bolts are being re-tightened frequently and still failing in operation. This re-tightening process creates significant downtime whilst not preventing bolt breakages.

The JEMTEC Solution addresses all Mill Liner Bolted Joint failure modes.

Outcome: With JEMTEC, bolts are tightened once with no re-tightening or additional shut-downs.

>>> See Diagram Below

Increasing bolt tensions can lead to more frequent bolt breakages.  Bolts are still failing in operation after adjusting installation tensions up to 90% yield strength.

The JEMTEC Solution addresses all Mill Liner Bolted Joint failure modes.

Outcome: With JEMTEC, bolt tension can be reduced and should not need to be re-tightened.

>>> See Diagram Below

Relaxation in the bolted joint causes tension to drop immediately after tightening and verification.  Bolts are still failing in operation when tensioned exactly to their given target.

The JEMTEC Solution addresses all Mill Liner Bolted Joint failure modes.

Outcome: With JEMTEC, bolt tension can be set once with no re-tightening or additional shut downs.

>>> See Diagram Below

Relaxation and tension loss in the bolted joint stills occurs despite efforts to tighten in the best sequences. Increased complexity will increase downtime without preventing bolt breakages.

The JEMTEC Solution addresses all Mill Liner Bolted Joint failure modes.

Outcome: With JEMTEC there is no need for additional complex install procedures.

>>> See Diagram Below

Tension measurement only monitors a symptom of the core problem. Bolts are still failing in operation even with the ‘correct’ tension 

 

The JEMTEC Solution addresses all Mill Liner Bolted Joint failure modes.

Outcome: With JEMTEC, there is no tension loss and no tension measurement required.

>>> See Diagram Below

In reality, mill bolts are still failing in operation, even when tensioned “correctly” 
(Bolts are also being re-tightened multiple times creating more downtime)

The JEMTEC Solution addresses all Mill Bolted Joint failure modes.

Outcome: With JEMTEC, bolts are tightened once with no re-tightening or additional shut-downs.

>>> See Diagram Below

In reality, bolts are still failing in operation even when tensioned “correctly”
(Increasing bolt tension (up to 90% yield strength) can lead to more breakages)

The JEMTEC Solution addresses all Mill Bolted Joint failure modes.

Outcome: With JEMTEC, bolt tension can actually be reduced and will not need to be re-tightened.

>>> See Diagram Below

In reality, bolts are still failing in operation even when tensioned to given target
(Tension relaxation means bolt tension is lost soon after verification)

The JEMTEC Solution addresses all Mill Bolted Joint failure modes.

Outcome: With JEMTEC, bolt tension can be set once with no re-tightening or additional shut downs.

>>> See Diagram Below

In reality, Liner installers not likely to stick to new complex bolt tightening procedures
(Tension relaxation will still lead to bolt tension loss and create more variation)

The JEMTEC Solution addresses all Mill Bolted Joint failure modes.

Outcome: With JEMTEC there is no need for additional complex install procedures.

>>> See Diagram Below

In reality, Bolts are still failing in operation even when tensioned “correctly”
(Tension measurement only monitors a symptom on some bolts without addressing failure modes)

The JEMTEC Solution addresses all Mill Bolted Joint failure modes.

Outcome: With JEMTEC, there is no tension loss and no tension measurement required.
