Screw Conveyor Auger Shaft Drive End Break

Screw Conveyor Auger Shaft Drive End Break

How operational loads break the drive shaft of a horizontal screw conveyor auger

Questions and queries asked following a screw feeder shaft breakage on a 15m long fertiliser dust transfer feed conveyor


If you have rotating shafts breaking at the drive-end of the auger shaft you may have a combination of bending and torsional fatigue. You are welcome to read the series of emails and responses below to a screw conveyor auger drive end failure.

15 Ways to Remove Operational Risk

15 Ways to Remove Operational Risk

To increase reliability, you need to decrease the chances of failure occurring. Each chance of failure creates risk. Operating risk can be mitigated and managed by meeting all 15 Precision Maintenance excellence targets.

This list of precision maintenance excellence targets is how to ensure component parts, and the equipment they are in, always operate with optimal reliability. Each requirement must be met to the highest standard. By doing this your equipment and machinery are operating with the least microstructure stress possible and getting utmost reliability.

The Company That Made Its Machines Breakdown

The Company That Made Its Machines Breakdown

Abstract: Many companies struggle with constant plant and equipment problems despite doing the very best they know how to keep their plant and machinery reliable. Their real problem, which they cannot see for themselves, is that what is done in the company is completely wrong for creating highly reliable production equipment. If you cannot “see” how reliability is destroyed in your business, then you are doomed to suffer poor reliability and low uptime forevermore.

Example ACE 3T Maintenance Procedure with Inspection & Test Plan (ITP)

Example ACE 3T Maintenance Procedure with Inspection & Test Plan (ITP)

Here is a great example from an industrial operation of a maintenance procedure using an Accuracy Controlled Enterprise (ACE) 3T standard operating procedure (SOP) format. To make it better would need photos and/or videos included for critical tasks. 3T stands for Target-Tolerance-Test, which are the minimum criteria needed to specify maintenance task quality and prove compliance. The 3T’s are a simple maintenance work quality assurance technique we invented to maximise the chance of doing outstandingly high-quality maintenance work that brings you outstanding plant and equipment reliability.

Screw Conveyor Auger Shaft Mid-Point Breaks

Screw Conveyor Auger Shaft Mid-Point Breaks

Are your screw feeder and trough screw conveyor auger shafts snapping in half?

Analysis of a broken screw feeder shaft on a granular Copper Sulphate Bagging Hopper Feed Screw explains how stress cause shaft failure


If you have rotating shafts breaking at the centre of the span then you quite likely have a metal fatigue problem. Take a read of the report below.


The 316L stainless steel screw feeder shaft on a 3200mm long, 260mm diameter, 1:1 pitch flight screw broke in the middle. The shaft was 50mm Schedule 40 316L stainless steel pipe. The screw flight was 6mm thick 316L plate stitch welded to the shaft. The screw had been replaced new only 4 weeks prior. The screw was removed from the trough in two pieces and the break was at the middle of the screw. The break was generally square to the shaft.

The Connection Between Equipment Risk and Equipment Reliability

The Connection Between Equipment Risk and Equipment Reliability

A slide deck of a presentation made by Mike at the SIRFRt WA Maintenance Roundtable November 2011.

Mike goes into depth with risk quantification, plotting techniques, along with connecting maintenance related risk to business risk levels. The presentation also explores using reliability as an element in the risk equation and discusses a few different ways to minimize risks.

So, What’s Still Wrong with Maintenance

So, What’s Still Wrong with Maintenance

Enterprise Asset Management and Maintenance will Always be Spectacularly Unsuccessful at Delivering Failure-Free Equipment, Until you Change to an Equipment Wellness Paradigm

—

The role of Maintenance is to eliminate operating equipment risks. Yet, organizations using Preventive and Predictive Maintenance strategies still have equipment breakdowns. They still have forced outages and stoppages. They consistently get emergency repairs. So, what makes today’s Maintenance paradigm so unsuccessful at equipment risk elimination? Because it is the wrong paradigm to use. The right mindset to have is an equipment wellness paradigm!

The Galvanic Corrosion Piping Trap!

The Galvanic Corrosion Piping Trap!

The wrong combination of metals in electrical contact create a Galvanic Corrosion Trap that will cause many failures and costs in the future

Abstract:

The Galvanic Corrosion Trap. The wrong combination of metals can produce a corrosion cell of unequal voltage where one metal gives up its electrons and corrodes away. If the corrosion is not detected it will result in eventual failure of the equipment. Galvanic corrosion prevention is a design selection issue that one must always be aware of, as it can arise with the simplest of decisions. This article highlights a galvanic corrosion problem often seen in industry and sometimes missed by the person selecting equipment.

Benchmarking Operating CAPEX vs. Replacement Asset Value (RAV)

Benchmarking Operating CAPEX vs. Replacement Asset Value (RAV)

Is there a percent of replacement asset value benchmark for run and maintain capital expenditure?

Replacement asset value (RAV) is a performance indicator of expenditure related to the operation and care of the plant or equipment vs. CAPEX expenditure needed to replace the plant or equipment. Many people ask if there is a replacement asset value benchmark for the operating cost.

When To Use Stainless And Alloy Steel In Place Of Plastic Or Carbon Steel Items

When To Use Stainless And Alloy Steel In Place Of Plastic Or Carbon Steel Items

When To Use Stainless And Alloy Steel In Place Of Plastic Or Carbon Steel. There are many times when it is false economy to use carbon steel and plastic items. It is often better to use stainless and alloy steels instead. They last longer and deliver a lower life cycle cost.

Human Factors in Human Error Prevention

Human Factors in Human Error Prevention

Understanding and Using Human Factors for Human Error Prevention and Mistake Proofing Gets You a Great Safety Advantage

There are many businesses around, even national and international sized companies, who have done an OHS risk assessment for their operations and still have poor workplace safety performance and lousy safety statistics. Clearly they got something seriously wrong when they undertook their operational health and safety (OHS) risk assessment process.

Rate of Occurrence of Failure

Rate of Occurrence of Failure

The Rate of Occurrence of Failure (ROCOF) curve is the sum of all the individual component failure curves across the service life of an asset. As shown below, it looks like a bathtub, giving it the nickname, a bathtub curve.

Equipment reliability is malleable by choice of policy and quality of practice.
