1. Overview

The 35-ton 3-axle bulk cement trailer is a pressure discharge tanker specifically designed for transporting and unloading dry bulk materials such as cement, fly ash, lime powder, and mineral powder. The fluidized bed and pneumatic discharge system allows fast, dust-free unloading into silos. Built with high-strength steel and a corrosion-resistant coating, this trailer is the industry standard for cement plants, construction sites, and bulk material depots.

2. Key Features

• 35-ton payload capacity – Optimized for 3-axle legal weight limits (total GVW ~40–45 tons)

• Pneumatic discharge system – Compressed air fluidizes powder for fast unloading (1.2–1.5 tons/min)

• 3 axles – 13T–16T per axle, total GVW 40–48 tons

• Horizontal or vertical tank design – Horizontal is standard for semi-trailers

• Fluidized bed (air pads) – Multiple air pads ensure complete discharge with low residual (0.3–0.5%)

• Discharge height – Up to 15–20 meters (direct into silo)

• Discharge distance – Up to 30–50 meters horizontal (hose length)

• Manhole / filling hatches – 2–3 large openings with dust seals

• Safety features – Pressure relief valve, burst disc, safety ladder, and platform

• ABS braking system – Standard

• Corrosion-resistant coating – Epoxy primer + polyurethane top coat for cement (alkaline) resistance

6. Buying Guide

Provide the following for an accurate quote:

1. Material type (cement, fly ash, lime powder, other – affects coating and material compatibility)

2. Material density (t/m³) – determines required tank volume for 35-ton payload

3. Unloading requirements (discharge height and distance to silo)

4. Tractor specifications (must have PTO-driven air compressor OR auxiliary diesel compressor)

5. Destination country (for pressure vessel certification and road legal compliance)

6. Optional needs (2 compartments, air suspension, aluminum rims, food-grade coating)

Key tips:

• Compressor requirement – Tractor must have a suitable screw compressor (typically 6–10 m³/min at 2 bar) OR purchase an auxiliary diesel compressor mounted on the trailer

• Single material only → 1 compartment is simpler and cheaper

• Two different materials (cement + fly ash mix on site) → 2 compartments required

• Long haul / rough roads → Air suspension + EBS recommended

• Coastal / humid environments → Request hot-dip galvanized chassis + marine-grade paint
