Description

Technical Field

[0001] The utility model belongs to the technical field of concrete production, and in particular relates to a raw material conveying device for concrete production. Background Art

[0002] Concrete production uses cement as a binder, sand and stone as aggregates, and water in a certain proportion. The cement concrete obtained by mixing is also called ordinary concrete. In the past, the most common cement was lime-based cement, such as lime paste, but sometimes hydraulic cement is also used, such as calcium aluminate cement or silicate cement. Non-cement-based concrete is different from other concretes. It directly bonds various aggregates together. Non-cement-based concrete includes asphalt concrete bonded with asphalt and polymer concrete using polymers as binders. In the concrete production process, the concrete raw materials in the silo need to be transported to the mixing station. Since the raw materials accumulate in the silo for a long time, cement is easy to clump. The agglomerated cement is directly transported to the mixing station, which has a certain impact on the quality of concrete produced subsequently.
