Pneumatic Unloading Fly Ash Tanker
The Pneumatic Unloading Fly Ash Tanker is a specialized, heavy-duty dry bulk transport trailer engineered specifically for the safe, high-volume road haulage and automated pneumatic discharge of fly ash, bottom ash, slag powder, and fine thermal power plant combustion residues. Because fly ash is characterized by its abrasive nature, ultra-fine particle size, and low bulk density (approx. 0.5 – 0.7 $t/m^3$), the tanker is fabricated from high-tensile, wear-resistant carbon steel (Q345B/Q355B) with reinforced internal hopper walls and wear-protected discharge manifolds. Equipped with multi-section fluidized air slides powered by a heavy-duty diesel engine or PTO-driven rotary screw air compressor (10–12 $m^3/min$ airflow at 0.2 MPa working pressure), it achieves rapid, zero-contamination pneumatic unloading into elevated power plant or construction silos with a minimal residual rate ($le 0.2%$). Paired with 3 commercial heavy-duty axles, mechanical or air suspension, and dual-line WABCO ABS/EBS pneumatic braking, it delivers exceptional highway stability, durability against abrasion, and operational reliability. Fully certified under ISO9001, CCC, CE, DOT, and SGS standards.

Key Structural & Performance Features
1. Abrasion-Resistant Carbon Steel & Low-Density Volume Optimization
- High-Strength Wear-Resistant Steel: Engineered from high-tensile Q345B/Q355B carbon steel with reinforced thickness at high-wear internal hopper zones to resist the abrasive scouring action of dry fly ash particles.
- Volumetric Capacity for Low-Density Ash: Designed with a generous volumetric footprint (up to 65 $m^3$) to accommodate the low bulk density of fly ash, maximizing payload weight per trip without violating highway axle load limits.
- Computerized Submerged-Arc Welding: Fully fabricated using automated welding technology to ensure absolute air-tight structural integrity under continuous pneumatic pressurization cycles.
2. High-Efficiency Fluidization & Pneumatic Unloading
- Multi-Section Air Slide System: Outfitted with premium vulcanized permeable canvas air slides that evenly distribute compressed air across the hopper bottoms, fluidizing compacted fly ash into a free-flowing state.
- High-Volume Air Supply: Powered by an onboard 10–12 $m^3/min$ rotary screw air compressor driven by an independent diesel engine, providing steady airflow to push ash up to 30 meters high into storage silos.
- Low Material Residuals: Steep conical hopper angles and optimized blow-by piping minimize material retention, achieving a residual rate of less than $0.2\%$.
3. Rigid Chassis Integration & Braking Safety
- Robust Q345B Sub-Frame Backbone: The tank body is securely welded to an integrated high-tensile structural steel frame that absorbs torsional twisting and dynamic road loads during heavy-duty transit.
- WABCO ABS/EBS Pneumatic Braking: Dual-line air braking system incorporating WABCO ABS/EBS and emergency relay valves, ensuring synchronized, dependable stopping power under full maximum payload conditions.
- Overpressure Protection Systems: Fitted with calibrated safety relief valves that automatically vent excess air if internal operating pressure exceeds safe engineering thresholds, ensuring total operational safety.
Commercial & Logistics Terms
- Warranty Policy: 3-Year warranty for the main tank shell and structural framework; 1-Year warranty for axles, air compressor, diesel engine, and discharge valves.
- Delivery Lead Time: 30 – 35 working days upon order confirmation and engineering drawing approval.
- Packaging & Shipping: Nude packing; shipped via Bulk Cargo vessel or Ro-Ro vessel.
