The running speed of the screw conveyor is determined for different materials, and the material particle size affects the slip, impact, and abrasion. The higher the number of revolutions, the greater the amount of material slip.
However, it is not possible to increase the conveying capacity by increasing the speed of the drive shaft. Some materials will have a large impact force on the spiral blades and increase the wear of the blades and the U-shaped groove. In this case, it is necessary to select a larger model to effectively increase the conveying capacity. The large-diameter screw shaft is used to enhance the torsional strength of the tube shaft, and the number of hanging bearings is reduced to increase the throughput of the material. The motor with high power should be accurately selected according to the amount of transportation and the distance. If the power is small, the material transportation speed is slow. The motor is easy to burn due to excessive load, and the power will increase the production cost.
