The thickness of the screw feeder blade has a very important influence on the actual use of the screw conveyor, if the screw feeder blade is too thin, the screw feeder lacks the intermediate shaft, all the stress are on the blades.
Therefore, the selection of a suitable thickness of the screw feeder blade, directly affect the use of the screw conveyor effect.
1. Leaf blade Wheelbase is too small, screw feeder pipe diameter selection is improper.
When conveying powder or flake materials, often because the blade wheelbase is too small, resulting in excessive extrusion pressure, direct damage to the blade, with the rotation of the shaft, the thick blade will also produce a certain amount of damage.
2. The pipe diameter is small, the size of the material exceeds the pitch.
Smaller pipe diameters can also cause excessive stress. Causing serious damage to the blades. At the same time in the use of screw conveyor when the size of the material can not exceed the pitch, once the large material into, the screw feeder blades will deform or even twist, this situation we recommend the material crushing, so that the screw feeder blades can be effectively resolved, while reducing the blade speed, or choose reinforced blades, to achieve this effect.
