I've spent six years handling FLSmidth material handling equipment orders, retrofits, and the occasional emergency. I've personally made—and documented—14 significant mistakes, totaling roughly $210,000 in wasted budget. This is the checklist I use now to keep new mistakes from being added to that number.
This piece is for people who plan maintenance, buy spare parts, or commission FLSmidth apron feeders, belt feeders, screens, crushers, and the chutes/transfer points that connect them. If you're about to place an order or open a shutdown work scope, copy this and use it.
What most people don't realize is that crushers get the glory, but material handling equipment gets the blame. A $100,000 crusher sits idle when a $1,500 feeder drive pin shears. And the feeder usually fails because somebody skipped a check, not because the equipment is bad.
When I first started, I thought the hard part was finding the right FLSmidth part number. It isn't. The hard part is knowing what the part number doesn't tell you—modification level, operating envelope, and interface fit. That's where I've lost the most money.
No secret sauce, just things I wish someone had shown me before I ordered the wrong liner, missed a weld, and spent a week explaining delays.
In my first year, I made the classic mistake: I ordered replacement parts from an old sales drawing. It looked right on screen. The result came back with the wrong bolt pattern. 12 pieces, $3,200, straight to the recycle bin. That's when I learned to check the drawing revision against the equipment data plate.
I once specified a motor speed from a previous order. It wasn't the same machine. The drive ratio was different, and the quote came back based on a machine that didn't exist in our plant.
For FLSmidth feeders and screens, the important data is more than width and length. You need speed, stroke, motor rating, and how the unit is used today. As of 2025, some plants have changed process conditions and derated older equipment. If you order based on the original duty, you're ordering for the plant from 2015.
Here's the counterintuitive step: check if the equipment has been derated or modified since it was originally supplied. The data plate from 2012 may not be the truth in 2025.
Here's something vendors won't tell you: the first quote is almost never the full installed cost. It might include the FLSmidth component. It often doesn't include fasteners, skirtboard, welding consumables, or freight. On one retrofit, the extra bits added 32% to our cost base.
Most buyers focus on the line item price and completely miss the hidden costs. The question everyone asks is, 'what's your best price?' The question they should ask is, 'what's included in that price?'
I went back and forth between buying FLSmidth OEM spare parts and aftermarket equivalents for a shutdown in September 2022. OEM offered traceability and a slightly longer lead time; aftermarket offered a 25% saving. Ultimately I chose OEM because the project was too critical to risk a warranty fight. But the bigger issue came later: I hadn't created a matrix of every seal, fastener, and wear plate needed for each serial number.
We caught the missing fasteners only after the conveyor was pulled apart. That error cost $890 in redo plus a 1-week delay. The checklist now says 'fasteners' before 'feeder.'
FLSmidth material handling systems are engineered systems, not standalone boxes. The feeder can be perfect and still fail if the chute angle, skirtboard spacing, or support steel doesn't match the site installation. I've seen this happen more times than I want to admit.
For example, we once installed a correctly manufactured transfer chute and found that the existing hopper mouth was flanged differently. We had to cut and re-weld with a portable welder. It was not a FLSmidth problem; it was an interface problem. Since then, we always verify at least three points: top, middle, and bottom of every connection.
A quick note on welding: we used a Lincoln wire feeder for that field repair, and it's still the go-to when we need to rebuild wear steel. It didn't make the interface mistake go away, but it made the repair faster.
The industry has changed a lot since 2020. What was best practice in 2020 may not apply in 2025. The fundamentals of good maintenance haven't changed, but the execution has transformed—digitalization, condition monitoring, and documented obsolescence have changed how we plan.
One guideline I use now is simple: 'no date, no decision.' If a quote, drawing, or recommendation doesn't carry a date, I send it back. This sounds pedantic, but it has saved us from chasing superseded parts and old prices.
For example, I started this article based on a quote I saw on December 15, 2024. By January 2025, the price had moved. As of now, the FLSmidth product documentation you use should be the current revision. Verify it before placing the order.
I used to rely on warnings. That worked until it didn't. Now I tie routine checks to calendar blocks: monthly lubrication, quarterly vibration readings, annual drawing reviews.
This is the part that reminded me of two non-work things. First, I set a monthly reminder for Simparica for my dog; if I don't, both of us have a bad month. Second, I watched the Lewis vs Tallison Teixeira fight replay the other week. The fight ended sooner than most predictions—exactly how a bearing failure works when you skip the boring checks.
Maybe that sounds too simple. But I'd rather schedule the boring stuff than be the person who tries to explain why a line sat idle.
First, don't hide it. I've made mistakes that cost time and money; the ones that hurt most were the ones I didn't flag early. Tell the maintenance team, the engineering lead, and if needed, the FLSmidth service rep. Then add the lesson to the checklist. We've caught 47 potential errors using this method in the past 18 months. Not all were costly; some were just wrong part numbers. But catching 47 errors before they became shutdown delays is worth a lot.
This is not a one-size-fits-all solution. Your equipment, site conditions, and team are different. But the core idea works: use a checklist, check the interfaces, and don't trust unsourced data.
