What is a twin screw conveyor?

Double screw conveyor is a kind of mechanical equipment used to convey powdery, granular and bulk materials. It consists of two co-rotating helical impellers and pipes. The materials are conveyed through the propulsion of the helical impellers. Compared with the traditional single-screw conveyor, the double-screw conveyor has higher conveying capacity, better sealing and smaller footprint, so it is widely used in chemical industry, metallurgy, building materials and other industries.

The two screw impellers of the double screw conveyor can be arranged in layers or in the same layer. The double-screw conveyor arranged in layers is suitable for occasions that require two conveying, for example, when making cement, it is necessary to convey the powdery raw materials and the mixture to the mixing silo, and then convey the mixture to the coal mill. The double-screw conveyor arranged on the same floor is suitable for occasions that require higher conveying capacity, such as in the sintering process, it is necessary to convey high-temperature sintered materials to the cooler or storage bin.

The main advantage of the double screw conveyor is that it has good sealing performance, which can effectively prevent the leakage of materials and the entry of external impurities, thus ensuring the cleanliness and safety of the production environment. At the same time, compared with the traditional single-screw conveyor, the double-screw conveyor has a larger conveying capacity and can meet higher production requirements. In addition, due to its compact structure and small footprint, it is more flexible in layout.

However, the twin-screw conveyor also has some disadvantages. For example, due to the friction and extrusion of the material during the conveying process, it is prone to problems such as material accumulation and blockage, and requires regular cleaning and maintenance. In addition, due to the complex structure and relatively high cost of the double-screw conveyor, it is necessary to consider the balance between economy and practicality.

In short, the double screw conveyor is a widely used conveying equipment with excellent performance. Through its advantages in sealing, conveying capacity and floor space, it provides effective support for the production of various industries.
