Fu type chain conveyor is used for horizontal(or slope 15 )conveying of powdery, small granular materials. The advantages of this product are: novel structure, reasonable design, reliable running, energy-saving, high efficiency and long service life. All the materials are transported in the sealed box without leak. Rolling on the track with less wear and tear, this product has been widely used in building materials, chemical, thermal power, food processing, mining and other industries.: working principlethere are friction and internal pressure exist in the bulk material, when the conveyor chain and accessories move, bulk material in conveyor machine groove is pulled with the same direction of conveyor chain, then the pressure will be added within the bulk particles, so as to increase the internal friction within the particles to insure the stable, the all form a continuous flow, like water.
