Description

Technical Field

[0001] The utility model relates to the technical field of production and processing of asphalt raw materials, in particular to a vertical modified asphalt raw material mixing device. Background Art

[0002] Asphalt mixture is a general term for a mixture made by mixing mineral materials and asphalt binder. According to the material composition and structure, it is divided into continuous grading and discontinuous grading mixtures. According to the composition of mineral grading and the size of the void ratio, it is divided into dense grading, semi-open grading, and open grading mixtures. According to the size of the nominal maximum particle size, it can be divided into extra coarse type, coarse type, medium type, fine type, and sand type asphalt mixtures. According to the manufacturing process, it can be divided into hot mix asphalt mixture, cold mix asphalt mixture, recycled asphalt mixture, etc. Asphalt concrete is a kind of artificially mixed ingredients, which contains mineral materials, crushed stone or crushed gravel, stone chips or sand, mineral powder, etc., which are mixed in a reasonable proportion and stirred under strict control.

[0003] During the mixing and stirring process of existing modified asphalt raw materials, the raw materials need to be put into the mixing tank from the feed port. Due to the poor fluidity of the asphalt raw materials, it is easy to cause blockage at the feed port, which requires manual unblocking, affecting the production and processing efficiency. Therefore, we have launched a new vertical modified asphalt raw material mixing device. Utility Model Content
