The project is located in an asphalt mixing station in Zouti County, Jiangsu Province. A large amount of dust is generated at the gravel feeding port, discharging port and waste port. By installing dust concentration sensors in the corresponding areas, the detected dust data is transmitted to the spray sub station and the master control system, and the atomization host is controlled to carry out high-pressure spray dust reduction, achieving the beneficial effects of automatic dust reduction, water conservation, and improving the on-site operating environment.
