During the operation of the concrete mixing plant, dust problems inevitably occur due to the raw materials including sand, gravel, aggregates, and powder. When dust is discharged into the air for a long time without control, it can cause serious dust pollution and bring adverse effects to the environment. Therefore, dust control measures are imperative. Next, let's talk about how to effectively control the dust pollution generated by the concrete mixing plant?
Firstly, establish a closed material yard environment. Due to the backward technical level of China's building materials industry, the fine sand and gravel have not been washed with water, and the dust content is high, making it easy to raise dust during storage and transportation. Therefore, it is necessary to implement closed management of the material yard. Generally, colored insulation boards are used to prevent the spread of dust and reduce noise pollution during work.
Secondly, the entire sealing of the concrete mixing plant. The principle is the same as the material yard, which also uses colored insulation boards for sealing. The main station structure, operation control room, and conveyor must be enclosed.
Furthermore, the dust removal of the cement silo. Generally, installing a dust collector on the top of a cement silo can effectively reduce dust pollution.
In addition, spiral nozzles can be added to the concrete mixing plant to improve the nozzle structure, forming a water curtain during water injection, and playing a certain role in suppressing the dust generated during the main machine feeding.
