Description

A shale shaker structure for screening of road surface reclaimed materials

Technical Field

The utility model relates to a road surface reclaimed material screening technical field, concretely relates to a shale shaker structure for road surface reclaimed material screening.

Background

With the basic formation of the national highway network, the development of the highway is switched from 'construction as a main' stage to 'construction and maintenance as well as repeated' stage. The highway asphalt pavement maintenance project only exceeds 2 kilometers per year, and about 2 hundred million tons of waste pavement materials are generated per year. The pavement recycling technology is used, so that the production cost is saved, and the effects of energy conservation and emission reduction can be achieved.

In the pavement regeneration technology, the recycled pavement materials are crushed and screened before entering an asphalt concrete mixing plant for recycling. In the process of crushing and screening the recycled road materials, the recycled road materials need to be screened in sequence to select the recycled materials with different particle specifications. When fine materials are screened (the maximum diameter of the fine materials is less than or equal to 5mm), the screened reclaimed materials have small particles and high powder content, and are wrapped with asphalt, the asphalt is easy to stick on a screen, so that blockage is caused, and the screen is difficult to clean.
