Tank Volume
We setUsable tank volume in cubic metres (CBM), based on cargo density, target payload and working margin.
Panda Mech Pneumatic Dry Bulk Tanker
Fly Ash Tanker Trailer for Bulk Transport
We build the tanker around your real transport job. First, we need your target payload and the bulk density of the fly ash — how much it weighs for its volume. We also check local axle limits and your receiving silo. Then we set the tank volume, axle setup, tank aeration and discharge system before production.

Quick Answer
What Tanker Should You Use for Fly Ash?
For dry fly ash, we normally use a sealed pneumatic dry bulk tanker. It unloads the powder with compressed air into a silo. We size the tank from your fly ash bulk density and target payload. Then we check the empty trailer weight, axle loads, tractor and receiving silo before we confirm the final setup.
A pneumatic tanker is the right starting point when
Your fly ash is dry, moves in bulk and needs to be unloaded with compressed air into a silo or enclosed system.
Tell us before we configure the tanker if
Tell us if the ash is wet, hard to flow or unusually corrosive. Also tell us if the silo is very high or the discharge pipe is long.
What is fly ash?
Fly ash is a fine powder collected from combustion-gas cleaning systems. It is common in coal-fired power plants and other industrial processes. Its density and flow can change from one source to another. That is why we prefer your actual cargo data when we size the tanker.
Background reference: Control Union — Fly ash, lime, cement and sand.

Axle & Suspension
We configureAxle count, axle load and suspension for your destination market and road condition.
Tank & Chassis
We configureTank and chassis setup for your cargo, tank volume, payload and tractor-trailer dimensions.
Pneumatic System
We matchTank aeration, compressor or other air source, and piping for your unloading route.
Discharge Setup
We matchOutlet and discharge setup for your pipe route, silo inlet height and receiving site.
What Changes When You Carry Fly Ash Instead of Cement?
The same type of tanker can carry cement or fly ash, but the setup may be different. Fly ash can have a different density and flow. That can change tank volume, tank aeration and legal payload.
| What Changes | Bulk Cement | Fly Ash | What We Do |
|---|---|---|---|
| Bulk density | Usually more consistent within one cement type | Can change a lot by source and production process | We calculate the usable tank volume again from your fly ash density and required payload. |
| Particle / flow behavior | Fine dry powder requiring fluidization | Can flow differently depending on source, particle size and composition | We set the tank aeration and discharge system around how your fly ash actually flows. |
| Moisture | Must remain dry | Moisture can make the ash harder to flow and unload | We use the right seals and operating setup to help keep the cargo dry and easy to unload. |
| Tank sizing | Payload + cargo density + legal vehicle weight | Payload + actual ash density + legal vehicle weight | We do not copy the tank volume from a cement tanker. We size the fly ash tank from payload, density, empty trailer weight and legal vehicle weight. |
| Pneumatic unloading | Air source, tank aeration and discharge pipe must work together | The same basic system works, but the ash itself must be checked | We match the air source, tank aeration, discharge line and receiving silo as one complete unloading system. |
| Legal payload | Depends on trailer weight, tractor weight and local road rules | The same legal weight rules still apply | We check the empty trailer weight, tractor weight, axle loads and local road limits before we confirm the payload. |
The tanker type may be the same, but the final setup may not be. Send us your actual fly ash data when you have it. We will size the trailer for the material you really carry.
Loading & Containment
Keep Fly Ash Dry During Loading and Transport
Moisture can make fly ash cake together and become harder to loosen with air. Poor seals can also cause dust leaks and air loss. We therefore check the loading opening, manhole seals, valves and pipe joints as part of the tanker setup.
Loading condition affects unloading performance.
Keeping the cargo dry and the tank sealed helps the ash flow and unload more reliably.
Manhole and sealsKeep moisture out and help keep dust inside the tanker.
Loading connectionA controlled connection reduces open dust release during loading.
Fill levelCorrect loading helps avoid overfilling, rejected loads and unnecessary cleanup.
Valves and pipe jointsGood sealing reduces fly ash leakage and air loss during pneumatic operation.
Tank Sizing
How We Size Your Fly Ash Tanker
We start with your cargo and local vehicle limits. From there, we work out the usable tank volume, axle setup and final tanker build.
What We Calculate From
01
Bulk Density
Shows how much the fly ash weighs in each cubic metre.
02
Moisture
Shows whether the ash may cake, bridge or become hard to loosen with air.
03
Flow Behavior
Affects tank aeration, how much material stays inside, and how well the ash unloads.
04
Target Payload
This is the cargo weight you want to carry on each trip.
05
GVW / Axle Limits
Shows how much legal payload is left after tractor and empty trailer weight are included.
06
Tractor & Route
Confirms fifth-wheel height, tractor compatibility and the road conditions the trailer will face.
How We Reach the Final Size
1. Required payloadStart from tonnes per trip.
2. Bulk densityUse the cargo weight and density to estimate the required tank volume.
3. Trailer tareCheck how much legal vehicle weight is still available for cargo.
4. GVW and axlesCheck total vehicle weight and how the load is shared across the axles.
5. Tractor compatibilityCheck fifth-wheel height, kingpin, air and electrical connections, and the unloading air source.
6. Final tank volumeConfirm the usable CBM, axle setup, chassis and pneumatic unloading setup.
Approximate cargo volume = required fly ash weight ÷ bulk density
This formula is only the starting point. We then check empty trailer weight, axle loads, road limits, tractor compatibility and working margin before we confirm the final tank size.
Pneumatic System
How Panda Mech Configures the Fly Ash Unloading System
We treat the air source, tank aeration, discharge line and receiving silo as one system. The goal is steady unloading from the tank to the silo. A larger compressor alone does not guarantee this.
The air source must match the full unloading route
We match the compressor or other air source to the tank, discharge pipe and receiving silo. We do not choose it as a separate part.
Pipe length and silo height affect unloading
A long pipe makes the ash harder to move. A high silo, small pipe or many bends can add even more resistance.
Cargo condition affects how well the ash moves with air
Dry, loose fly ash is easier to mix with air and unload. Wet or compacted ash can move more slowly and may need a different aeration setup.
Why discharge distance matters
Research on pneumatic ash conveying shows that pressure drops as air and material move through the pipe. Pipe length, diameter, slope and air flow all affect this pressure loss. These factors can change how much fly ash the system can move.
What this means for your project: two sites using the same tanker can unload differently if their pipe and silo conditions are different. This is why we ask for both horizontal discharge distance and silo inlet height before we configure the air system.
Engineering reference: Stevanovic et al., Powder Technology 254 (2014), “Analysis of transient ash pneumatic conveying over long distance and prediction of transport capacity.” View abstract.
How the Ash Moves
Compressor / Air SourceProvides the air used for unloading
Tank AerationLoosens the powder with air
Tank PressurePushes material toward the outlet
Discharge PipelineAdds resistance as material moves
Silo InletMoves material up and into the silo
Filter / VentLets displaced air leave the silo
Receiving Site
Receiving Silo & Unloading Performance
We set up the tanker for the full discharge route. Silo height, pipe length, pipe diameter, bends and filter condition all affect how hard the ash is to move.
What We Check Before We Set Up the Tanker
Silo inlet height
A higher silo makes the ash travel farther upward. This adds resistance and can change the air-system setup.
Horizontal discharge distance
A longer discharge pipe creates more pressure loss and can slow unloading.
Pipe diameter & bends
Small or restrictive pipework and too many bends make the ash harder to move.
Filter / vent capacity
The silo must let air escape while fly ash enters. A blocked or undersized filter can cause backpressure, which means pressure builds up inside the silo.
Receiving backpressure
We use the site conditions to match the air source, tank pressure and discharge setup.
We match the tanker and receiving route as one system.
A larger compressor cannot fix a blocked pipe or too much pressure inside the silo.
If Unloading Performance Drops
Start with the symptom. It usually tells you which part of the system to check first.
Discharge becomes slower than normalCheck whether the ash is wet or compacted. Then check for air leaks, air-source problems and a blocked silo filter.
Tank pressure rises but flow stays lowCheck the discharge pipe for narrow sections, too many bends or a blockage. Also check for pressure building up inside the silo.
Too much material remains in the tankCheck the tank aeration and cargo condition. Also make sure the unloading steps match the tanker setup we supplied.
Before Unloading: 6 Quick Checks
Follow the operating steps supplied with your final tanker setup.
Cargo conditionConfirm the fly ash is dry and suitable for pneumatic unloading.
Air sourceConfirm the compressor or other air source is ready.
Air linesCheck joints and hoses for obvious leakage.
Discharge connectionConfirm hose and pipe connections are secure.
ValvesConfirm the valves are ready for the supplied operating sequence.
Silo filter / ventMake sure displaced air can leave the receiving silo.
YES
ISOLATED
COMPARTMENTS
ISOLATED
COMPARTMENTS
Can One Tanker Carry Both Cement and Fly Ash?
Yes. We can build one tanker for both materials, but each material must have its own fully isolated compartment. We do not configure cement and fly ash to share the same tank compartment.
Separate CompartmentsCement and fly ash are stored in independent, fully isolated compartments.
Compartment VolumeWe size each compartment from the required payload and bulk density of the material carried in that compartment.
Internal PartitionThe internal separation keeps the two materials isolated during loading, transport and unloading.
AerationWe configure the aeration arrangement for the material handled by each compartment.
Independent DischargeWe match outlets, piping and unloading sequence to the separate-compartment layout and receiving site.
Full Trailer Axle LoadWe calculate the empty trailer weight, cargo distribution and axle loads for the finished dual-material tanker.
Send the cement payload and fly ash payload separately.
We use both payload requirements to split the compartment volume. We then calculate the total tank size and axle loads for the complete trailer.

What Changes Your Fly Ash Tanker Price?
We price the tanker for the job it needs to do. Tank size, axles, suspension and pneumatic equipment can all change with the cargo, destination and unloading route.
Tank volumeA larger or more complex tank changes material use and fabrication work.
Axle / suspension setupAxles and suspension change with payload, road condition and destination requirements.
Tank and structural materialTank material and chassis material are separate choices. Both can change the final price.
Compressor / air-source arrangementA trailer-mounted compressor, tractor-driven air source or external air source uses different parts and changes the price.
Special discharge requirementA long pipe, high silo or restrictive route may need a different aeration, piping or air-system setup.
Order quantity and destinationOrder quantity affects production planning. Shipping cost and time depend on the destination and sailing schedule.
We quote the tanker setup you actually need.
The quotation should match the tank size, axle setup, structure and pneumatic system your route actually needs.
What we need before we quote
Send us your destination country, target payload and order quantity. If you know the fly ash density, tractor details, silo height and discharge distance, send those too. We use this information to prepare a project-specific setup instead of a generic model price.

Fly Ash Tanker FAQ
What type of tanker is used for fly ash transportation?
For dry fly ash, we normally use a sealed pneumatic dry bulk tanker. It unloads the powder with compressed air into a silo. We size the tank from cargo density and payload, then match the axles, tractor and pneumatic system to your route.
How many CBM do I need for fly ash?
Start with the payload you need on each trip. Divide that weight by the fly ash bulk density to estimate cargo volume. We then check empty trailer weight, axle loads, legal vehicle weight and working margin before we confirm the final usable tank volume.
What fly ash density should I send Panda Mech?
Send the actual or supplier-specified bulk density if you have it. If not, send us the fly ash source and any cargo data you already know. We will tell you what else we need before sizing the tanker.
Can one tanker carry both cement and fly ash?
Yes. We can build one pneumatic tanker for both cement and fly ash. The two materials must use separate, fully isolated compartments. We size each compartment from its own payload and density, then check the finished trailer axle loads.
Do cement and fly ash need separate compartments?
Yes. If one tanker carries both materials, cement and fly ash must stay in separate compartments. We do not configure them to share the same tank compartment.
Can Panda Mech match the tanker to my existing tractor?
Yes. Send us the tractor make and model, fifth-wheel height and available air source. If you use a power take-off (PTO), tell us that too. We check the tractor-trailer connection before production.
Can the tanker unload into a high silo?
Yes. Tell us the silo inlet height, horizontal distance, pipe diameter, major bends and filter condition. We use this information to match the tank aeration, air source and discharge path to the receiving site.
Why does fly ash sometimes unload slowly?
Common causes are wet or compacted ash, poor tank aeration, air leaks or restrictive piping. A high silo, too many bends or pressure building up inside the silo can also slow unloading. We match the tanker to the full discharge route to reduce these problems.
What information do you need for a quotation?
Send us the destination country, fly ash type or source, target payload, quantity, road condition, silo inlet height and horizontal discharge distance. If you know the bulk density, tractor model, pipe diameter, local axle limits or target unloading time, send those too.
