How to prevent the dust of concrete mixing plant? 1. Closed material field is used. Most construction sites use open type material field, and most raw materials such as gravel are not washed. If closed material field design can be adopted, it can effectively reduce the dust emission of the mixing plant to the surrounding environment.

The design of water-spraying dust control for main engine is adopted. When feeding in concrete mixing plant, great dust and impact dust will be generated. After the nozzle structure is modified, a pressure pump is added to form a water curtain after spraying water from the nozzle, which can effectively reduce the dust content in the air.
