When procuring a powder tank truck (also known as a pneumatic bulk trailer), you must prioritize the tank material, typically Q235 carbon steel, aluminum alloy, or stainless steel, depending on the weight requirements and corrosion resistance needed. The effective volume (cubic meters) and rated load capacity must align with your local road regulations. Pay close attention to the discharge speed (≥1.2t/min) and the residual rate (≤0.3%), as these directly impact operational efficiency. Additionally, ensure the truck is equipped with a reliable air compressor (e.g., 12m³ double-cylinder) and a high-quality fluidized bed to prevent powder clogging.
