The colorful pipe belt conveyor project at the Port of Java is one of Yuxin Machinery's overseas projects, which adopts D600 (BW 2250mm) tubular belt conveyor system. The conveyor length of BC3 and BC4 is 4 kilometers each, which is used to meet the demand for large-scale and high-efficiency coal conveying in Java Port. The project is equipped with colorful pipe belt conveyor, which is not only recognizable, but also realizes full sealing conveying of materials through the closed pipe structure, which effectively reduces dust and material scattering, and adapts to the changing climate and complex terrain of the port.
