Powder tanker trailers are designed to handle dry, powdered materials like cement, flour, and lime. Their cylindrical bodies, with smooth, non - porous interiors, are specifically engineered to prevent material adhesion, allowing for easy unloading. These powder trailers rely on a pneumatic discharge system, using compressed air to move powders through dedicated pipelines, achieving dust - free and efficient transfer. Constructed with abrasion - resistant high - strength steel, they can withstand the harsh nature of powdered substances. Specialized inlet and outlet ports facilitate quick loading and unloading. To minimize environmental impact, advanced dust - filtering systems are integrated. Their enclosed design also protects the transported powders from moisture, maintaining product quality, making them crucial for construction, food, and chemical industries.
