1. The pipe chain conveyor, also known as the plate chain conveyor, is a continuous conveying equipment dedicated to conveying powder, small particles and small pieces of bulk materials, which can realize horizontal, inclined and vertical combined three-dimensional conveying. The working principle of the pipe chain conveyor is to take the chain as the driving component to drive the animal materials along the pipeline inside the closed pipeline. It has stable performance in the conveying system Energy saving, environmental protection and sealing

2. Screw conveyor, commonly known as auger, is made of steel. It is a machine that uses the motor to drive the screw to rotate and move the materials to achieve the purpose of conveying. The working principle of screw conveyor is that the rotating screw blade moves the materials to transport the screw conveyor. It has the advantages of simple structure, small cross-sectional area, good sealing, convenient operation, easy maintenance and convenient closed transportation

3. First of all, the screw conveyor has large unit power consumption and short conveying distance. It is easy to cause material breakage in the conveying process. It must not be used to transport granular feed. Moreover, it has rapid wear on the blades and chute. Especially in the fast screw conveyor, the maintenance of the casing and the replacement of the blades are more frequent

4. It is sensitive to overload and uneven feeding, which is easy to cause blockage. However, the cost of pipe chain conveyor is high due to the requirements of equipment material. In case of serious disc wear, * * * replace it in time, and pay special attention to the maintenance and repair of the chain, because the chain wheel drives the chain to rotate during the conveying operation of the equipment, Then the disc on the chain drives the materials to form a stable material flow in the ring pipe. Therefore, once the chain fails, it will directly affect the operation of the equipment, so the chain needs to be inspected and maintained once every 3-6 months

5. Compared with the screw conveyor, the conveying distance of the pipe chain conveyor is several times longer than that of the screw conveyor, the horizontal conveying distance is 60m, and the lifting height can reach 40m. It can also realize three-dimensional steering conveying, with flexible conveying and no dead zone in the pipeline. The important thing is that the materials are not blocked, which can limit the integrity of the materials. Moreover, it has low energy consumption, explosion-proof design and air tight design, fully enclosed conveying and no dust, No pollution, in line with the requirements of environmental protection.
