What are the factors to consider when designing a screw conveyor?

At present, the screw conveyor equipment should be user-centered to determine the direction of development for the downstream industry chain services. Therefore, large capacity, continuous, high speed, automated mechanical product design of the combined modular industry has become a new trend in the development of conveying machinery. Even conveying machinery process is with the development of new technologies, conveying machinery production must also change.

Screw conveyor design and production should first consider the characteristics of the transported materials, abrasive, viscous, water content, acidity and alkalinity, and other factors, to achieve the design of different materials and the appropriate model. Secondly, for different materials to determine the operating speed of the screw conveyor, material particle size affects the slip, impact and abrasion. The higher the number of revolutions, the greater the amount of material slip. But can not just increase the speed of the drive shaft to improve the conveying capacity, some materials will have a greater impact on the spiral blade, and make the blade and U-shaped trough body wear increased. In this case to effectively increase the conveying capacity actually need to choose a larger model, assembled with a large diameter spiral shaft to enhance the torsional strength of the shaft, reduce the number of hanging bearings installed to increase the amount of material throughput. Choose how much power of the motor according to the amount of conveying and the distance between how much to accurately select the type, the power is small, the material transportation speed is slow, the motor is easily burned due to overload, the power will increase the cost of production.
