Description

Technical Field

[0002] Concrete is a primary material in modern construction, and its composition is quite complex, containing some ultrafine powdery structures. These ultrafine powdery structures generally need to be incorporated before final batching. Current mixing structures are mostly designed for normal-sized materials; using them to incorporate ultrafine materials results in insufficient dispersion, and the resulting clumps of ultrafine material are small and difficult to break up by existing mixing structures. Furthermore, uneven spraying occurs when adding the concrete to the production equipment, thus requiring improvements to the current equipment. Summary of the Invention
