The material code you provided, 0160404F2000, corresponds to a specific component found in the older model of Zoomlion Heavy Industry's concrete pump truck. Specifically, this code refers to the central mixing shaft in the hopper of the concrete pump truck.

The central mixing shaft serves a crucial function in the mixing process of the concrete pump truck. It is responsible for blending and agitating the materials within the hopper, ensuring a homogeneous mixture of concrete before it is pumped out.

The main function of the central mixing shaft is to rotate and stir the materials in the hopper, which typically include cement, aggregates, water, and other additives. As the shaft rotates, it effectively combines these components, breaking up any clumps or aggregates and promoting a consistent distribution of materials.

Through its rotational motion, the central mixing shaft facilitates the proper hydration and activation of the cement, ensuring that the concrete mixture achieves the desired strength and consistency. It helps to achieve a uniform composition, eliminating any variations or inconsistencies in the mixture that could affect the quality of the final concrete product.

Furthermore, the central mixing shaft helps to prevent the settlement or separation of materials during transportation and storage within the hopper. By continuously agitating the mixture, it maintains a homogeneous state, preventing the heavier components from settling at the bottom and ensuring a consistent quality of the concrete.
