A 2-axis (or 2-axle) powder tanker truck is a specialized heavy-duty vehicle designed to transport dry bulk materials such as cement, fly ash, flour, and chemical powders. These tankers typically use a pneumatic discharge system, often featuring a V-shaped or “flying gray” tank design to ensure efficient material flow and minimal residue.

Technical Specifications

Load Capacity: Commonly ranges from 25cbm to 45cbm (cubic meters), with weight capacities typically between 30 and 40 tons.
Material Construction: Tanks are often built from carbon steel (Q235) for durability or aluminum alloy (5083) to reduce tare weight and increase payload.
Discharge System: Uses an air compressor (often powered by an auxiliary diesel engine) to pressurize the tank and “fluidize” the powder for unloading through a 4-inch discharge hose.
Dimensions: Average trailer lengths range from 40 to 45 feet, making them more maneuverable in urban or confined spaces compared to larger 3-axle configurations.
