Dry Bulk Trailer Specially designed for powder and granular bulk materials, the conveyor is made of lightweight aluminum alloy or high-strength steel, with tank and head of 5mm thickness, and achieves residue-free conveying through pneumatic discharging. The advantages are that the loading and unloading efficiency is more than 50% higher than that of traditional trucks, and the moisture and oxidation-proof characteristics are suitable for the transportation of materials such as cement, grain and plastic granules. The key design includes trapezoidal cross-section anti-roll-over structure and wear-resistant inner coating, which is widely used in the raw material supply chain of building material factories and chemical plants.
