What Is a Suction–Pressure Conveying Truck?
A suction–pressure conveying truck is a specialized vehicle designed for steel mills, municipal engineering, and various industrial applications. Its primary function is to suction, transport, and pressure-discharge powder and granular materials. By combining Vacuum suction technology with high-pressure pneumatic conveying, the truck enables fast loading, sealed transportation, and efficient unloading of bulk materials.
Typically equipped with a large-capacity tank (15–30 m³), a high-performance Vacuum pump, and a powerful pressure-conveying system, the vehicle can handle a wide range of materials such as powders, granules, dust, sludge, and industrial residues. This makes it an essential piece of equipment for industries that require clean, efficient, and dust-free material handling.
Key Features and Standard Operating Procedure
Suction–pressure conveying trucks are engineered for heavy-duty industrial operations.
Main technical features include:
-
Tank volume: Usually 15–30 m³, meeting different bulk material transport needs.
-
Drive configuration: Commonly 6×4 or 8×4, ideal for heavy loads and complex road conditions.
-
Emission standard: Most models comply with China VI emission regulations, aligning with environmental requirements.
Standard operating procedure:
-
Start-up & inspection: Start the vehicle and ensure the Vacuum pump and conveying system are in normal condition.
-
Material suction: Insert the suction hose into the material pile, then activate the vacuum pump. Recommended vacuum pressure: –0.06 to –0.08 MPa.
-
Transportation & discharge: Once the tank is full, turn off the vacuum pump and transport the load. At the destination, activate the high-pressure conveying system to unload. Recommended discharge pressure: 0.2–0.4 MPa.
Operators must monitor pressure levels, avoid overloading, and prevent pipe blockage to ensure safe and efficient performance.
Widely Used in Industrial and Municipal Applications
Suction–pressure conveying trucks are widely used in steel mills for slag powder cleaning, in cement plants for bulk powder transfer, in chemical factories for granules and powder handling, and in municipal engineering for sludge and dust removal.
With strong suction capacity, sealed transport, and high-pressure discharge, these trucks significantly improve material handling efficiency while reducing labor intensity and preventing secondary pollution. They have become indispensable equipment in modern industrial and municipal operational systems.
