Before the manufacture of conveying machinery products, many factors must be considered, including manufacturing materials, technology, etc.; among them, the choice of materials is very important. The choice of materials not only determines the quality of the machinery, but also fluctuates in the price. ; Screw conveyors generally use steel in the manufacturing. In the manufacture of screw conveyors, sometimes due to the particularity of the materials to be conveyed, stainless steel is also used. Compared with ordinary steel, stainless steel has obvious advantages. It has outstanding advantages in ensuring the cleanliness and viscosity of the conveyed materials. Advantages; the biggest disadvantage of this material is the price, and the expensive price is that this kind of material cannot be popularized and applied.
Determine the spiral blade form according to the nature of the conveyed material. When conveying materials with good scattering properties such as wheat and rice, full-faced blades should be used; when conveying oily materials with high viscosity and easy adhesion, belt blades should be used to prevent clogging. It should be noted that for conveying raw grains and rice and other materials, in order to prevent the materials from being broken, screw conveyors are generally not used.
