The zipper machine is designed reasonably, has a novel structure, and a long service life. It is a new product used for horizontal (or inclined ≤ 15 °) conveying of powdered, granular, and small materials. The zipper machine is at the advanced level in technology in China, and its performance is significantly better than screw conveyors, buried scraper conveyors, and other conveying equipment. It is an ideal new type of conveying equipment.

Zipper machines are widely used in building materials, chemical, mining, metallurgy, power, grain and oil processing, machinery, transportation, ports, and transportation industries. The Fu type chain conveyor utilizes the characteristics of internal friction and lateral pressure of loose materials to ensure a stable state between material layers, forming a continuous overall flow under the action of the conveying chain. The chain conveyor is mainly composed of a head section, a middle section, an optional section, a tail section, a conveying chain, a feeding port, and a driving device. The driving device is divided into two types: left and right. The driving device model is selected according to the conveying volume and length. The feeding port is divided into three types: upper feeding port, side feeding port, and two feeding ports. The discharging port is the head discharging port, and can also be used for middle bottom layer discharging and middle side discharging, for users to choose from.
