The U-shaped screw conveyor is convenient for intermediate loading and unloading, and the conveying direction can be reversed or both directions can be conveyed simultaneously. During the transportation process, materials can also be stirred, mixed, heated, and cooled. The material flow can be adjusted by loading and unloading the gate. But it is not suitable to transport materials that are prone to spoilage, high viscosity, clumping, and large blocks. During use, it is necessary to maintain the sealing of the material groove and to have appropriate gaps between the screw and the material groove. A screw conveyor usually consists of three main parts: the main body of the screw conveyor, the inlet and outlet device, and the driving device. The U-shaped screw conveyor body is composed of three parts: the head section, the middle section, and the tail section. In general, during the final assembly at the factory, the middle sections of the screw conveyor are arranged in order of length. The longest middle section is close to the head section, while the middle sections of the same length are placed together. If there are special requirements, the arrangement order is given when placing an order. There are thrust bearings installed in the head section of the screw conveyor to withstand axial forces, and bearings are installed in the middle and tail sections to support the screw shaft. In addition, there are radial bearings that can move axially in the tail section of the screw conveyor to compensate for errors in the length of the screw shaft and adapt to temperature changes
Spiral conveyor, commonly known as twisted dragon, is widely used in industries such as chemical, building materials, grain and oil, feed, sludge, metallurgy, mining, plastic, medicine, etc. Its U-shaped groove shell is widely used for materials with high viscosity, easy jamming, and poor fluidity. It is a conveying equipment in industries such as chemical, building materials, grain and oil, feed, sludge, metallurgy, mining, plastic, medicine, etc. It is suitable for horizontal conveying, inclined conveying, vertical conveying, and other forms of granular or powdered materials. Its conveying distance ranges from 2 meters to 70 meters, and the outer diameter specifications range from 120-600mm. The materials include carbon steel and stainless steel. The conveying shaft is divided into axial spiral and non axial spiral, and the shell is divided into circular and U-shaped. Special specifications can be made according to customer needs
