3 Axle Bulker Cement Trailer 45 Ton

The 3 Axle Bulker Cement Trailer 45 Ton is a specialized pneumatic bulk powder transport semi-trailer engineered for efficient delivery of cement, fly ash, lime powder, and other fine dry bulk materials. With a 42 cubic meter tank capacity and 45-ton payload rating, this cement bulker trailer serves ready-mix concrete plants, construction sites, and industrial powder users across Africa, the Middle East, and Southeast Asia.

The V-shaped tank body with fluidized bed design ensures complete material discharge with minimal residual. The tank bottom features a W-shaped double-cone fluidization system with porous aeration canvas that uniformly fluidizes the powder, enabling smooth gravity discharge through pneumatic pressure. Residual rate is typically less than 0.3% — critical for maximizing delivered material quantity and minimizing waste.

A dedicated diesel engine-driven air compressor (typically Weichai or Xichai 4102 engine) produces 12 m³/min of compressed air at 0.2 MPa — sufficient to fluidize and discharge the full 42m³ load in approximately 35–40 minutes. The compressor operates independently of the tractor, enabling discharge at sites without external air supply or electrical power.

Three BPW 13-ton axles with parabolic leaf spring suspension provide stable transport of the 45-ton powder load. The WABCO ABS braking system ensures safe stopping. The tank is constructed from high-strength Q345B steel with 5mm body walls and reinforced dished heads, pressure-tested to 0.3 MPa to ensure leak-free pneumatic discharge operations.

The loading manway (500mm diameter) on top of the tank enables fast filling from cement plant silos via pneumatic loading lines. The dust collector on the manway prevents powder escape during filling, maintaining clean operations and environmental compliance. A pressure relief valve set at 0.25 MPa protects against over-pressurization.

This cement bulker trailer is essential for ready-mix concrete supply chains, bulk cement distributors, and construction material logistics operators. Its 42m³ capacity (approximately 50 tons of cement) enables efficient long-distance transport from cement factories to distribution depots and construction sites.

Optional features include aluminum tank construction (reducing tare weight by 2,000 kg), level sensors for remote monitoring, GPS tracking integration, and multiple discharge outlets for sites with multiple storage silos.
