The FU chain conveyor is a new type of equipment used for horizontally (or with an inclination ≤ 15°) conveying powdery and granular materials. It features reasonable design, novel structure, long service life, reliable operation, high energy efficiency, good sealing, safety, and convenient maintenance. Its performance is significantly better than that of screw conveyors, buried scraper conveyors, and other conveying equipment. It is at the advanced domestic level in terms of technology and is suitable for efficient, energy-saving, and well-sealed conveying of powdery and granular materials horizontally or with an inclination. It is widely used in many industries such as building materials, chemical engineering, grain processing, mining, and electricity.
