The 5-Point Verification Checklist for FLSmidth Equipment Deliveries: A Quality Inspector's Playbook

When This Checklist Applies

You're expecting a delivery from FLSmidth. Maybe it's a Raptor cone crusher for your copper operation, an apron feeder for a cement plant, or a critical gearbox that's been on backorder for weeks. The crate arrives. You sign the paperwork. The installation crew gets to work.

Then someone notices something's off. A mounting bracket that doesn't match the drawing. A serial number that doesn't align with the order. A surface finish that's rougher than spec.

I've been on both sides of that moment. As a quality compliance manager reviewing roughly 200+ equipment deliveries annually, I've rejected about 8% of first deliveries this year alone due to specification discrepancies. Not because the equipment was necessarily bad, but because what arrived didn't match what was ordered in ways that would have caused problems down the line.

This 5-point checklist is what I use. It's designed for anyone who's accepting FLSmidth equipment — whether you're a plant manager in Tucson (I've seen plenty of those photos), a procurement specialist, or a site engineer. It takes about 30 minutes to run through properly and has saved us an estimated $150,000 in potential rework over the past 18 months.

Here's how it works.

Step 1: Cross-Reference the Order Package (Before Unpacking)

Most people start by opening the crate. Don't. Start with paperwork.

Pull up the original purchase order (PO) and the FLSmidth order acknowledgement. You're looking for three things:

• Part numbers match: Not just the description, but the exact FLSmidth part number. A Raptor XL900 cone crusher and a Raptor 900 are not the same thing (I learned that the hard way in Q1 2024).
• Revision level: Equipment gets updated. The revision letter on the packing slip should match what you ordered. If it's different, there's a reason — either a functional change or, occasionally, an error.
• Serial number range: For large equipment like SAG mills or screens, FLSmidth assigns serial numbers that correspond to manufacturing batches. If your gearbox has a serial number that's 2,000 units off from what you expected, that's worth investigating.

Here's something vendors won't tell you: packing slips are sometimes generated before final quality checks. I've seen cases where the paperwork says "Passed QC" but the equipment itself has a tag indicating it was flagged for review. Always compare the physical tags against the order — not just against the packing list. (note to self: this has caught three discrepancies in the last year alone)

Step 2: A Visual Walk-Down Against the General Arrangement Drawing

Once you've verified the paperwork, crack open the crate — but don't get hands-on yet. This step is about looking.

Print out the FLSmidth General Arrangement (GA) drawing for the component. Walk around the equipment and check:

• Overall dimensions: Length, width, height. A discrepancy of even an inch can matter when you're installing a crusher on a pre-poured foundation. I once rejected a feed chute that was 2 inches wider than spec — would have required re-cutting the steel support structure.
• Orientation markers: Direction arrows, inlet/outlet labels, lift points. These should be clearly marked and correspond to the drawing. Missing or ambiguous markers are a red flag.
• Welding quality: Look for uniform bead width, no pitting, proper termination. FLSmidth's internal standards (I've referenced them for years) specify that structural welds must be free of cracks, undercut, and excessive porosity. If something looks sloppy, it's worth flagging.

People assume a major manufacturer like FLSmidth sends perfect equipment every time. The reality is that even with their quality systems in place — and FLSmidth A/S Denmark does have rigorous processes — individual units can have issues. A rushed production schedule or a new welder on the line can introduce variability. My Q2 2024 audit showed a 3% non-conformance rate across all FLSmidth deliveries. That's actually quite good, but 3% of a $2 million order is still $60,000 worth of potential headaches.

Step 3: Check the Critical Dimensions (Don't Trust the Tape)

Here's where most checklists fall short. People look at dimensions and think, "Good enough." But in mining and cement equipment, tolerances are tight for a reason.

Identify the 3-5 critical dimensions on the GA drawing — bolt patterns, shaft diameters, flange thicknesses. These are typically called out with tolerance bands (e.g., ±0.5mm). Measure them yourself with a calibrated tool.

I use a digital caliper for smaller components and a measuring tape with a verified calibration sticker for larger ones. I do not trust the measurements on the packing slip unless I've confirmed them.

For example: In the delivery of a gearbox last year, the mounting bolt pattern looked right to the eye. But when I measured it, the center-to-center distance was off by 3mm. On a 500mm span, that's within some people's tolerance — but not within the FLSmidth spec of ±1mm. We rejected it. The vendor (in this case, not FLSmidth, but a subcontractor) claimed it was "within industry standard." It wasn't, per the contract. They redid the baseplate at their cost.

The 12-point checklist I created after that mistake has saved us an estimated $8,000 in potential rework since.

Step 4: Verify Protective Coatings and Surface Finishes

This is the step that most people skip — and it's where issues hide.

FLSmidth equipment, especially for cement applications, is coated to withstand abrasive materials and harsh environments. Check:

• Paint thickness: Use a dry film thickness gauge. Spec is usually 3-5 mils for standard applications, thicker for corrosive environments. If it's below spec, corrosion starts years earlier.
• Surface preparation: Between layers, the surface should be clean, dry, and free of contaminants. Peel off a small section of tape — if any coating comes off, adhesion failed. I've found this more often than I'd like on subcontractor-built components.
• Hardened surfaces: For crusher liners, mill liners, and wear plates, check the hardness stamp or use a portable hardness tester if you have one. The spec should match what you ordered. I ran a blind test last year with our site team: three liners from the same batch. Two were within spec. One was 8% below — would have worn out 30% faster. The cost difference was negligible at procurement but massive in lifespan.

From the outside, it looks like coating quality is a minor detail. The reality is that poor coating on a single critical component can lead to premature failure that costs 10x the part value in downtime. Our cement customers have taught me this the hard way.

Step 5: Run a Functional Test (If Feasible and Safe)

For rotating equipment — gearboxes, feeders, screens — a dry run test catches issues that visual inspection misses.

If the component is designed to be tested on site (some FLSmidth gearboxes are), set it up on a test stand or temporary setup:

• Listen for noise: Bearing rumble, gear whine, or irregular clicking. I've used a mechanic's stethoscope to isolate sounds — a consistent high-pitch whine often indicates misalignment; a knocking sound suggests a damaged gear tooth.
• Check for vibration: Use a vibration meter or an app (there are surprisingly accurate ones) to compare against FLSmidth's tolerance limits. A 10% increase over baseline is worth investigating.
• Verify rotation direction: This sounds basic, but I've seen a conveyor drive installed with the wrong wiring because the arrow on the housing was ambiguous. Always test before installation.

Here's something you might not know: functional testing on delivery day is not standard practice in many operations. Most people assume it'll work because it's factory-tested. But shipping vibration, temperature changes, or rough handling can loosen connections or shift components. That 30-minute test has prevented three incidents in my career — one was a gearbox with a loose internal bolt that would have failed after 200 hours.

Common Mistakes and Notes to Self

The biggest mistake: signing off before running the full checklist. I've done it myself. The pressure to get equipment on site and running is real. But 5 minutes of verification beats 5 days of correction. Every time.

Other mistakes I've made and learned from:

• Trusting single-source measurements: Always double-check with a second tool or method. My tape measure was 2mm off over 1 meter once — I'd been using it for months without rechecking calibration.
• Skipping the coating check on familiar equipment: The gearbox I rejected for coating failure last year came from a supplier I'd worked with for 5 years. Complacency is your enemy.
• Assuming FLSmidth's documentation is always current: I've found a drawing revision mismatch on a crusher delivery — the physical unit matched the older revision, not the latest spec. The vendor corrected it at their cost, but it delayed installation by two weeks.

The golden rule: document everything. Take photos (like the ones you'd take for "FLSmidth Tucson photos" to show site conditions), note measurements, and keep a log. That record has saved us during warranty claims more than once.
