Vehicles loading and unloading materials should take dust suppression measures such as watering and spraying. Transport vehicles should clean their wheels and bodies when leaving the departure area.

(5) Production process equipment, exhaust gas collection systems, and pollution control facilities should operate synchronously. When the exhaust gas collection system or pollution control facilities malfunction or undergo maintenance, the corresponding production process equipment should be stopped and put into use together after the maintenance is completed.

6. Concrete mixing plant

(1) Mixing plant

The mixing host and batching machine should be located in a closed mixing building, equipped with dust collection facilities; Raw material feeding, batching, and mixing equipment must be fully enclosed.
