A pneumatic bulk trailer is built around a sealed steel or aluminum tank divided into 3 to 5 compartments, each fitted with its own discharge valve so a single load can serve more than one customer without cross-contamination.
A pneumatic bulk trailer is built around a sealed steel or aluminum tank divided into 3 to 5 compartments, each fitted with its own discharge valve so a single load can serve more than one customer without cross-contamination. That compartment layout matters because cement, fly ash, and lime move as fine powder that gravity alone won't unload cleanly. This cement pneumatic trailer design uses an onboard air compressor and blower line to push material out through a discharge hose, which keeps dust exposure down compared to open dump trailers. SIGMA builds each dry bulk trailer with a rounded tank profile that resists internal material bridging during transport. Some export markets call this same unit a dry bulk tanker, though it hauls powder rather than liquid cargo.
