Auger conveyor, also known as screw conveyor, is made of steel, which is a kind of machinery that uses a motor to drive the spiral to rotate and move materials to achieve the purpose of conveying. It has the advantages of simple structure, small cross-sectional area, good sealing, easy operation, easy maintenance, convenient closed transportation, etc., But the unit power consumption is large, the conveying distance is short, it is easy to cause the crushing of materials in the conveying process, it is not suitable for conveying pellet feed, and the blades and troughs are worn quickly.

Pipe chain conveyor, also known as tubular drag chain conveyor, when working, the chain equipped with a disc scraper moves in the closed pipeline, relying on the scraper to push the material forward along the pipeline, which is an energy-saving and efficient continuous conveying equipment.It has compact structure, occupies little space, can change the conveying direction in three dimensions, is not affected by terrain, angle and height, the conveying process is carried out in a closed pipeline, the material is pollution-free, no dust flying, the conveying process is smooth, there is basically no internal movement between materials, less damage, to ensure the quality of materials, suitable for abrasive materials, will not produce system blockage, suitable for conveying a variety of forms of materials, the conveying of mixed materials, will not produce material stratification, large conveying capacity, low energy consumption, greatly reduce the operating cost of equipment, All moving parts are operated in a confined space, which is safe and reliable, can realize long-distance transportation, and can be arranged at will with multiple inlet and outlet ports to meet process requirements, easy to achieve centralized control, and improve the degree of automation.
