The invention belongs to the technical field of asphalt mixture production equipment, and particularly relates to a screen system for asphalt recycling materials. The screen system comprises a primaryscreening mesh, a fine screening assembly and a coarse screening assembly which are obliquely arranged in the horizontal direction, the fine screening assembly and the coarse screening assembly are arranged below the primary screening mesh and distributed in two columns, the oblique direction of the fine screening assembly is opposite to that of the primary screening mesh, and the oblique direction of the coarse screening assembly is the same as the primary screening mesh. According to the screen system for the asphalt recycling materials, the asphalt recycling materials can be quickly screened, accurate classification of the asphalt recycling materials is ensured, and the occupied area is small.
Description
technical field [0001] The invention belongs to the technical field of asphalt mixture production equipment, in particular to a screen system for asphalt recycled materials. Background technique [0002] As we all know, Recycling Asphalt Pavement (RAP for short) is to excavate or mill the pavement, recycle old materials, crush and sieve, and then add some new recycled materials and new asphalt to re-mix, if necessary, add Recycling agent is an applicable technology for obtaining recycled asphalt mixture that meets the road performance requirements of high-grade highways and is used to pave the pavement surface or base. By reusing asphalt and gravel in pavement materials, it is a modern environmental protection technology with the most economic value and social benefits to maximize the use of resources and protect the environment. Recycled materials normally need to be crushed and screened before they can be reused. [0003] Due to the wide range of particle sizes in recycl...
