Continuous helical blades are primarily used for conveying materials with high viscosity and compressibility. This type of helical surface not only completes the conveying task but also simultaneously mixes and blends the material. The inner mandrel moves forward, continuously performing processes such as fiber winding, compounding, sanding, and curing. Due to the continuous production, the equipment boasts advantages like convenient process control, low labor intensity, minimal pollution, a good working environment, high production efficiency, and stable pipe material quality.
