The reason most high-volume plants don’t perform to potential isn’t big flashy breakdowns. It’s small, daily losses – product on the floor, dust in the motors, workers with brooms instead of tools. And the solution to that isn’t a budget conversation. It’s an engineering one.
Stop calculating downtime wrong
When we discuss maintenance costs in business manufacturing, unscheduled downtime is the figure that springs to mind. And quite rightly – the situation in which an unexpected conveyor fails, and an entire production grinds to a halt while urgent repairs are drafted is an operational manager’s worst nightmare.
But that’s the obvious cost. The one that’s far more insidious is the accumulated drag of operating at 80% efficiency for a couple of weeks before something finally breaks.
OEE – Overall Equipment Effectiveness – is the measure that shines a light on this. It multiplies your availability, performance, and quality together into a single number. Plants that run at 70% OEE often believe it’s an acceptable position. What they don’t factor into that assumedly tolerable score of 70%, is what’s driving it down – the idlers that are wearing unevenly due to abrasive grit underfoot, the motors that are cycling up harder than they should because dust has compromised their cooling, the bearings that are failing ahead of schedule because no-one caught the misalignment two weeks ago.
These aren’t emergency failures. They’re micro-losses. And they stack.
Load zone integrity is where you lose the most money
The transfer point – where material drops from one conveyor to another – is the single highest-wear zone in bulk handling. The impact of falling material, the turbulence, the lateral forces on the belt edge: all of it happens here, continuously, across every shift.
Material spillage at this point isn’t just lost product. Every kilogram that lands on the floor represents abrasive grit that works its way under the belt, accelerates idler wear, and creates the kind of slow structural damage that doesn’t show up until a roller seizes or a belt tracks wrong.
Fugitive dust is the quieter problem. Fine particles suspended by belt movement migrate into motor housings and bearing cavities. They don’t cause immediate failure – they reduce Mean Time Between Failures month by month until a replacement cycle that should run 18 months runs 10.
Properly engineered conveyor skirting creates a sealed interface between the stationary chute wall and the moving belt surface, capturing material at the source rather than letting it escape outward. This is the primary line of defence against both spillage and dust migration, and it’s where the return on a properly specified system shows up fastest.
Replace the “run-to-fail” model with a walk-around standard
One of the most effective changes that a plant can implement, and costs almost nothing to implement, is a standardized daily walk-around checklist for equipment operators.
Not a management audit. An operator habit.
Operators working near conveyor systems every day will notice when a skirt seal has worn flush with the belt, when there’s fresh material accumulation outside a transfer point, or when a belt is running slightly off-center. These are 60-second observations. Without a structured prompt, they go unreported until the damage is visible.
With Total Productive Maintenance as the framework, operators share accountability for machine health – not just operation. This shift reduces the gap between when a problem starts and when maintenance knows about it. That gap is where the expensive repairs originate.
A simple checklist covering skirting wear, belt alignment, dust accumulation patterns, and seal condition can extend consumables’ lifecycle significantly. It also builds the data history needed to move from preventive maintenance schedules to genuine predictive maintenance using sensor-based triggers.
Cut manual cleaning out of your maintenance budget
Approximately one quarter of conveyor-related accidents are caused by material spillage while cleaning around the conveyor. When viewed through the lens of safety, managing spillage takes on a whole new level of importance. It is not just a KPI for operational efficiency but a measure of workplace safety and health.
Every shift that maintenance personnel are assigned to clean a transfer point or a conveyor path because of spillage is time that they are not spending performing the necessary preventative maintenance. Containment at the source eliminates the need for these laborers to work in a potentially dangerous location around moving equipment because that condition was created by a breakdown that already should have been prevented.
Facilities that embrace source containment often find that the personnel who used to clean up spillage can be reassigned to perform necessary inspection or lubrication tasks that extend equipment life and performance.
Modular components reduce shutdown duration
The time it takes to perform maintenance, including accessing and replacing wear parts, can have a huge impact on your OEE score. If a high-wear component fails, and then it takes a long time just to get to it and replace it, you are piling lost production on top of lost production.
Anywhere wear impacts on your uptime minimize the time necessary for changeouts during a scheduled maintenance period. Ensure that all regularly replaced wear components are modular and designed for quick replacement, preferably without special tooling. Also, consider differently designed skirts and chutes that resist wear better in the first place, possibly capital spares that can be swapped out in a few minutes.
