Dry Bulk Pneumatic Blower CFM & Unloading Pressure Calculator
Interactive engineering tool for dry bulk pneumatic carriers: model tractor-mounted blower CFM, tank fluidization aeration PSI, and product line discharge rates for Portland cement, fly ash, and hydrated lime.
Tank Aeration Fluidization
Aeration pads inject air into the hopper cones to aerate and fluidize compacted powders. Maintaining differential pressure between tank and discharge line prevents catastrophic line slugging.
15 PSI Relief Valve Safety
Standard aluminum pneumatic dry bulk trailers have ASME vessel limits rated at 15 PSI max. Operating at 12–14 PSI balances rapid discharge velocity while avoiding relief valve blow-offs.
Blower Detention Recovery
Unloading times exceeding 90 minutes burn expensive PTO fuel and add severe blower wear. Automated pneumatic detention invoicing recovers $95–$145/hour from consignees.

Bulk Pneumatic Material Properties & Blower Requirements
| Commodity | Bulk Density | Blower CFM Requirement | Target Tank PSI | Exspeedite TMS Verification |
|---|---|---|---|---|
| Portland Cement | 94 lbs / cu.ft | 450 – 550 CFM | 12 – 14.5 PSI | Automated silo capacity confirmation & digital scale ticket |
| Class F / C Fly Ash | 55 – 65 lbs / cu.ft | 500 – 650 CFM | 11 – 13.5 PSI | Aeration pad pressure differential monitor & delay alert |
| Hydrated Lime | 30 – 40 lbs / cu.ft | 600 – 750 CFM | 10 – 12.0 PSI | Fine-dust filter baghouse integrity check & clean-out log |
| Frac Sand / Proppant | 95 – 105 lbs / cu.ft | 400 – 500 CFM | 13 – 14.5 PSI | Wellhead staging geo-fence & 24/7 demurrage capture |
