The models of screw conveyor blades

What are the models of the screw conveyor blades? Common screw conveyor blade shape classification: a. Full-face spiral blade b. Long ribbon spiral blade c. Crescent-shaped spiral blade, d. Lade spiral blade.
A. Full-face spiral leaves full of formula for loose material, full-face blade fastening device, cannot be adjusted.
B. Long ribbon spiral blade This type of spiral consists of two or more different diameter of the ribbon spiral blade, the ribbon spiral leaves are left and right spiral helix, a blade set in another, through the rigid hanging. The ear is attached to the same pipe or shaft. A ribbon blade moves the material forward and the other strip leaves moving the material backwards, allowing the material to be absolutely and fully mixed.
C. Crescent-shaped spiral lobes have a strong stirring and loose role, suitable for conveying powder easy to caking materials.
D. Paddle spiral blade can adjust a certain angle of the blade spiral can make the material completely mixed, and can control the flow of materials. Standard Pitch Saw Corrugated Single Head Screws are serrated and bent on the outer edge of the spiral so that the moving material can be turned over and spilled to allow the material to be mixed thoroughly. This is a hot, advantageous.
The screw conveyor has the absolute advantage in solving the transport of dry cement, ore, coal, fertilizer and other easy to affect the surrounding environment of the powder material has the absolute advantage, while the screw conveyor in the delivery of materials can also be mixed, stirring and cooling operations and can be applied to a variety of materials unloading or loading and storage of scattered particles in the warehouse.
