The rapid development of China's green and circular economy has made it more important to deal with environmental pollution in urban suburbs. An effective solution is to turn mixed waste accumulated on the outskirts of cities into a valuable resource. By recycling and disposing of mixed municipal waste, it is possible to make effective use of this waste and reduce the impact of environmental pollution. In the process of sorting recycled aggregates from municipal mixed waste, the separation of light and heavy materials is the key technology affecting the quality of recycled aggregates.
In various solid waste treatment and resource fields, garbage sorting equipment (air screen) is widely used, and air screen is almost an indispensable equipment in the process of solid waste treatment and resource development. The main principle is to use the principle of aerodynamics to separate the light, small and heavy substances in the material under the joint action of controllable positive pressure airflow and negative pressure airflow, and separate the light matter and air, and bring it into the sedimentation chamber upwards or horizontally. Lightweight material is output through a lightweight material conveyor. Because of the upward airflow, the weight cannot support its gravity to settle on the heavy load discharge conveyor and be output.
Garbage sorting equipment (air screen) has the advantages of high control accuracy, stable performance, good sorting effect and sorting efficiency of more than 95%, which realizes the effective sorting of heavy material garbage. It can be widely used in the large-scale treatment of various large, medium and small garbage dumps.
