AI Technical Summary
Traditional mobile asphalt mixing equipment directly discharges dust particles ≥0.075mm, which harms health, affects the environment, and wastes resources.
The system employs a combination of drying equipment, cyclone dust collector, and bag filter. The cyclone dust collector uses centrifugal force to separate dust particles, while the bag filter further purifies the airflow. The dust particles fall into a recycling silo for reuse, reducing emissions.
This enables the recycling and reuse of dust particles, reducing secondary pollution and resource waste, and improving environmental protection.
