Technical Field

The invention relates to the technical field of asphalt processing, and in particular to a granular asphalt screening device.

Background Art

Asphalt is mainly used in industries such as coatings, plastics, rubber, and road paving. Asphalt pavement recycling is achieved by reusing asphalt and gravel in pavement materials to maximize resource utilization and protect the environment. Normally, recycled materials need to be crushed and screened before they can be used.
