[0002] In centrifugal casting production, particularly in the production of composite materials such as fiberglass reinforced plastics (FRP), precise and efficient raw material delivery is crucial for ensuring final product quality and improving production efficiency. Traditionally, centrifugal casting production has relied extensively on Jiaolong conveying devices for raw material feeding. These devices use a spiral tube within a wear-resistant tendon tube to rotate, propelling raw materials such as quartz sand along the tube. While Jiaolong conveying devices meet basic raw material transportation requirements to a certain extent, their numerous shortcomings in actual production applications have become a significant factor restricting production efficiency and equipment reliability.
