How This Cement Volume Scanner Prevented $330,000 in Production Losses At Heidelberg Materials
Article Summary
WingScan revealed a hidden cement production loss that traditional weighing methods failed to catch.
Based on in-depth conversations with Walt Weninegar of Heidelberg Materials, this case study shows how WingScan uncovered a hidden 100-ton-per-day shortfall worth about $330,000 in lost product—and why volumetric scanning gives plants better control than traditional weighing.

Problems show up immediately.
WingScan removed the 15–20 day delay between production errors and discovery. Operators now see issues in minutes.
-
Volume reveals the truth.
Weight fluctuates with moisture. Volume stays stable. Plants gain tighter mix control and clearer process data.
-
The financial case is obvious.
Less downtime. Fewer belt-scale failures. Better inventory accuracy. Most plants recover the cost in months.
Walt Weninegar thought his Heidelberg Materials plant was running smoothly.
The belt scales showed steady feed rates.
The monthly reports looked normal. Everything seemed under control.
Then he discovered the truth…
A seemingly small 100-ton-per-day shortfall had been silently eating away at production.
By the time they caught it during month-end reconciliation, 2,000 tons of clinker had vanished—roughly 2,200 tons of cement, about $330,000 in product value.
“The typical 15–20 day lag in identifying production errors was killing us,” Walt told us. “We were always playing catch-up, discovering problems weeks after they started.”
This was not a one-off incident.
Hidden losses occur at cement plants industry-wide.
The Hidden Cost of Traditional Belt Scales & Weighbridges.
Traditional belt scales and weighbridges have been the backbone of cement plant measurement for decades.
Plant managers trust them because they’ve “always worked.”
But here’s what most don’t realize: these mechanical systems are bleeding money in ways that don’t show up until it’s too late.
The problem runs deeper than you think.
Walt explained something urgent:
“You can’t find a dang electrician that knows how to calibrate a scale anymore,” he says. “And even when you do, you’re still dealing with mechanical parts that drift, wear out, and break down in our dusty environment.”
But the real eye-opener came when Walt’s team tried measuring alternative fuels and lightweight materials.
“We were trying to weigh seasoning on a belt scale designed for tons per hour, not pounds. When you’re weighing 50 pounds of material on a belt that weighs 2,000 pounds, you’re starting with a 4% error before you even begin,” Walt recalls.
The math is brutal: if your scale has a 500-pound error margin and you’re trying to measure 10 tons, that’s an automatic 4% loss in accuracy.
Multiply that across thousands of loads, and you’re looking at massive financial hemorrhaging.
While talking to Walt, it became clear that there are issues that kill profit at cement plants.
The Three Critical Problems Killing Your Profitability
1 Delayed Error Detection
Production discrepancies are identified weeks after they occur. Small daily measurement errors snowball into significant financial losses while you remain completely unaware.
2 Reactive Troubleshooting
Problems are only discovered during monthly reconciliation, leaving little time to adjust. You’re always fighting fires instead of preventing them.
3 Surprise Inventory Shortfalls
Output variances remain hidden until periodic inventory checks reveal the damage is already done.
How Modern Cement Volume Scanner Technology Changes Everything
Walt’s plant was one of the first to install WingScan’s LiDAR-based volumetric scanners.
The difference was immediate and dramatic.
Here’s what he told us:
“Real-time feed measurement eliminated that 15–20 day lag completely. Now we catch discrepancies within minutes, not weeks.”
Think about this: instead of discovering problems during monthly inventory reconciliation, his team gets a 20-day head start to fix issues and safeguard throughput.
No more 6-figure month-end surprises.
Now, you might be wondering, “how does a cement volume scanner work exactly?”
Let’s look at it step-by-step:
Two Reasons Why Volume Beats Weight For Cement Production
1. Volume Stays Stable When Weight Fluctuates
Walt told us, “Gypsum moisture changes a lot, but volume doesn’t change as much as mass does with moisture. Volume is relatively stable. When you operate off volumetric measurement and apply density, we saw a reduction in standard deviation.”
Essentially Walt is telling us WingScan is a game-changer for mix control and clinker chemistry consistency.
Traditional scales can’t distinguish between material and moisture.
You’re literally paying for water weight while using gravimetrics. LiDAR measures actual material volume, then applies density calculations for precise mass readings.
2. Catches Feed Problems Other Systems Miss
Besides remaining stable when weight fluctuates, Walt also told us something remarkable he noticed when monitoring alternative fuel feeds: “We were capturing these huge clumps going through and then just nothing. The LiDAR was so accurate it identified that our problem wasn’t with the measuring device – we had a feed problem.”
Why is this insight powerful?
It’s noteworthy because belt scales couldn’t detect these inconsistencies. The LiDAR revealed feed issues that were costing production efficiency.
Becoming problem-aware of previously invisible issues opens the door for real cost-saving solutions.
Let’s look at a few examples of how volume scanning is making cement plants run smoother in the real world.
5 Powerful Cement Volumetric Scanner Applications:
Raw Material Feed Control
Raw Material Feed Control
Maintaining consistent limestone, clay, and additive feeds is critical for kiln stability and clinker quality.
A cement volume scanner mounted above your conveyor relays real-time volume data directly to your PLC. Operators spot flow interruptions or surges immediately.
This means no more adjustments based on delayed data. No more off-spec clinker batches that cost thousands to correct.
Truck Load Optimization
Truck Loading Optimization
Under-loading wastes payload capacity and increases transportation costs. Overloading risks fines and spillage.
A special volumetric cement load scanner for haul trucks provides instant feedback during loading, so you can perfect payloads and ultimately maximize profit.
Manage Inventory Smarter
Easier Inventory Management
In many cement plants, reported inventory and what is actually in the yard don’t match. Phantom inventory builds up as small measurement errors that accumulate over time.
WingScan’s LiDAR cement volume scanner measures all your moving product, eliminating blind spots and manual guesswork.
The result is inventory counts that match reality and bills of lading that align with what’s really shipped—numbers both the plant and the receiver can trust.
Supporting Low-Carbon Cement
Supporting Less Carbon Intensive Cement Production
Producing low-carbon cement often involves replacing part of the clinker with supplementary cementitious materials like fly ash, slag, or calcined clay—and that only works with precise dosing.
A cement volume scanner keeps each material feed accurate and consistent, cutting down on rework and off-spec batches.
Combined with density and moisture data, volumetric measurement lets plants lower the clinker factor, optimize transport, and directly shrink their CO₂ footprint.
Maintenance Free
No Maintenance Hassle
Traditional belt scales mean constant recalibration, worn load cells, specialist call-outs, and lost production every time something drifts.
LiDAR cement load scanner systems flip that script: one-time calibration, no moving parts to wear out, and continuous operation without interruption.
