During the machining process of spiral blades, there are many fine nodes that need to be paid more attention to, especially the control of machining dimensions.

1. Good wear resistance and uniform wear, because during the blade processing, the rolling is uniform during the cold rolling process, the spiral curvature is uniform, the overlap of each piece is very high, and the interface is flat with small gaps.

2. The smooth appearance of the spiral blades requires very high requirements for their self-developed equipment. By selecting the appropriate pressure value and hardness of the mold, they can be produced.

3. Integrated spiral blades have outstanding advantages in assembly. The assembly and use process of spiral blades is simpler, effectively improving factory production efficiency.

4. Blades are important components for the output of materials in screw conveyors. Increasing the discharge port or extending the end of the material trough can solve the problem of poor or insufficient discharge. At the same time, a small section of counter rotating blades can be installed at the end of the discharge port material groove to prevent material blockage at the end.
