Description

Technical Field

[0001] This utility model relates to the field of concrete mixing technology, specifically a concrete mixing device for highway engineering construction. Background Technology

[0002] Concrete is a commonly used building material, composed of aggregates, cementitious materials, and slurry. It requires mixing equipment to ensure that the components are evenly mixed. Aggregates, as aggregates, have a significant impact on the strength of concrete structures. If large aggregates that do not meet the specifications are mixed into the concrete, it will reduce the density, consistency, and deformation of the concrete. Therefore, a concrete mixing device is needed that can screen out aggregates that do not meet the specified size during mixing.
