Technical Field
[0001] The utility model belongs to the technical field of asphalt production and relates to a crushing device for asphalt production. Background Art
[0002] At present, in the process of asphalt concrete production, hot materials (asphalt raw materials) and cold materials (sand and gravel, etc.) need to be mixed in a mixing drum. In order to prevent the asphalt raw materials and cold materials from being mixed and melted unevenly in the mixing drum, which affects the viscosity of the asphalt, the cold materials are generally heated in a heating drum before being mixed with the hot materials.
[0003] In the process of adding cold materials, the cold materials are generally placed in a cold material bin first, and one type of cold material is placed in one cold material bin. Before the cold materials are stored, the larger cold materials need to be initially crushed.
