Today, we will introduce an efficient conveying equipment
Spiral conveyors are widely used in the grain industry, building materials industry, chemical industry, machinery manufacturing industry, transportation industry, etc. Spiral conveyors are mainly used to transport various powdery, granular, and small block materials, including grain products such as grains, beans, and flour, building materials such as cement, clay, and sand, chemicals such as salts, alkalis, and fertilizers, as well as bulk cargo such as coal, coke, and ore. Spiral conveyors are not suitable for conveying materials that are prone to deterioration, high viscosity, large block size, and easy agglomeration. Apart from transporting granular materials.
Spiral conveyor is a mechanical device that uses an electric motor to drive a spiral to rotate and push materials to achieve the purpose of conveying. It can be transported horizontally, obliquely or vertically, with the advantages of simple structure, small cross-sectional area, good sealing, easy operation, easy maintenance, and convenient enclosed transportation. Spiral conveyors are divided into two types in terms of conveying form: axial spiral conveyors and shaftless spiral conveyors. They are also divided into U-shaped spiral conveyors and tubular spiral conveyors in terms of appearance. Axial screw conveyor is suitable for non viscous dry powder materials and small particle materials (For example: cement, fly ash, lime, grain, etc.) and shaftless screw conveyors are suitable for conveying materials that are viscous and easily entangled. The working principle of a screw conveyor (such as sludge, biomass, garbage, etc.) is that the rotating screw blades push the material to be transported by the screw conveyor. The force that prevents the material from rotating together with the screw conveyor blades is the weight of the material itself and the frictional resistance of the screw conveyor housing to the material. The spiral blades welded on the rotating shaft of the screw conveyor have different surface types depending on the conveyed material, including solid surface type, belt surface type, and blade surface type. The screw shaft of the screw conveyor has a thrust bearing at the end of the material movement direction to provide axial reaction force to the screw along with the material. When the machine is long, an intermediate suspension bearing should be added.
Spiral conveyor features:
1. It has a wide range of use and can be used to transport materials tilted, horizontal, or vertical upwards. It requires less space, has a large lifting angle, is easy to clean, and is easy to maintain.
2. Suitable for transportation in various environments, with characteristics such as acid, alkali, and salt water resistance. The entire machine has small size, high speed, accurate, fast, and uniform transportation speed.
3. The discharge end is equipped with a cleaning device, which has low noise and strong adaptability. The position of the inlet and outlet is flexible.
4. Different specifications of feeding machines can be customized according to customer needs, such as hopper size, conveying height, motor position, etc. The screw conveyor has a compact overall size and is easy to maintain.
