Product Overview
A pneumatic discharge cement tanker trailer bulk powder transport unit is not a standard liquid tanker. It is a sealed pressure vessel engineered to transport dry powdered materials—cement, fly ash, lime powder, mineral powder—and unload them using compressed air. The pneumatic discharge system differentiates it from gravity feed alternatives. Compressed air at 0.2–0.35 MPa is injected into the tank, fluidizing the powder so it flows like liquid through discharge pipes to storage silos up to 15 metres high and 5 metres horizontally.
This 3-axle 40-cubic-meter unit is built for cement plants, concrete batching stations, and large-scale infrastructure projects that require bulk powder delivered ready for immediate use. The V-shaped tank design enables complete discharge, with less than 1% material left inside. The fully sealed, closed design keeps moisture away from the cargo

Why Pneumatic Discharge Matters for Bulk Powder Transport
Gravity discharge cement tankers depend on slope and vibration, with obvious usage limits. Pneumatic discharge perfectly solves these three pain points:
- Fast Unloading Efficiency
Compressed air fluidizes dry powder, delivering 1.2–1.5 tons per minute. A full 40-ton load finishes unloading in 25–35 minutes, greatly cutting waiting time and improving daily transport trips.
- Flexible Long-Distance Conveying
It pumps materials 5m horizontally and 15m vertically into silos directly. No extra conveyor equipment needed, unlike gravity types that must park right above hoppers.
- Low Residue & Dust-Free
Residual material rate ≤0.2%, with barely 50kg left after discharge. Fully sealed structure avoids dust leakage and moisture absorption, protecting cement quality.
Built for Real Bulk Powder Transport Conditions
V-shaped Tank Design
V/Cone tank bottom plus internal fluidized beds guide material fully to outlet, discharge residue below 1%.
High-Strength Steel Structure
Tank: Q235B steel, 5–6mm shell, 6mm end plate; chassis Q345B manganese steel with automatic welding. Reinforced frame adapts to rough unpaved roads.
Internal Fluidized Bed System
Built-in air pads aerate powder for smooth flow. Matching valve manifold ensures stable airflow and clean pipeline discharge.
Independent Power Unit
Weichai diesel engine drives dual-cylinder air compressor, 0.2MPa, 12m³/min. Unload without tractor connection; strong bracket resists road vibration. Optional Multi-Compartment
2–3 separate sealed compartments with independent unloading. Transport different cement or fly ash in one trip without cross-contamination. Anti-Corrosion Inner Coating
Sandblasted inner tank with polyurethane coating, anti-rust, no cargo pollution, longer service life.
Airtight Manhole Sealing
500mm manhole with automotive rubber seal, keeps tank pressure stable, easy to replace and low maintenance.
Dustproof Electrical System
IP67 sealed wiring and full set of standard lights, high temperature and dust resistant for harsh working sites.
