1. The characteristics of raw materials to be transported, such as abrasiveness, must be considered in the design scheme. Wear resistant materials such as bauxite, artificial quartz or dolomite are transferred to the U-shaped shaft screw conveyor with suspension support frame. Transport non abrasion resistant materials such as rice husk and soda. The characteristics of raw materials become the main factor affecting the transportation capacity. The viscosity and water composition of raw materials determine the difference of transportation modes used by materials.
2. The operation validity of shaft screw conveyor also determines the size of transportation volume. The operating efficiency of the shaft screw conveyor is related to the particle size of the transported raw materials, which will affect movement, impact and damage. The higher the rotating speed, the greater the deviation of raw materials. As everyone knows, the increase of speed will cause the raw materials to rotate with the spiral rotation, which is also the unexpected movement of raw materials. In addition, the increase of speed will also cause obvious impact of raw materials, which will aggravate the serious damage of spiral gear and single layer of water storage tank.
3. The diameter of the shaft screw conveyor also determines the transportation volume. For the shaft screw conveyor, it is the total width of the groove. The key of long-distance axial screw conveyor using large-diameter pipe shaft is to use diameter pipe shaft, which not only improves the torsional compressive strength of pipe shaft, but also reduces the myopia of bent pipe shaft. This is conducive to reducing the total number of suspension system support points or the application of suspension system support points, thereby reducing the manufacturing cost.
4. The motor output power also determines the transportation volume. If the output power of the selected motor is too small, the operation rate of raw materials in the pipeline or storage tank will be very slow, which will seriously affect the efficiency of the transmission system, and the motor is likely to be damaged due to excessive load. Conversely, if the motor output power is large, it will increase the function loss and increase the product cost.
