  Introduction 

  In daily production, concrete mixing plants inevitably produce a large amount of dust due to the processing, mixing, and transportation of raw materials. These dust not only affect the working environment, but may also pose a threat to the health of employees, and may also cause environmental pollution. Therefore, developing an effective dust treatment plan is crucial for concrete mixing plants. (More information of concrete mixing plant are available on lutonmachinery.com)

  Dust Sources And Impacts

  • Dust Source

  The dust from the concrete mixing plant mainly comes from processes such as stone crushing, sand screening, transportation and mixing of cement and additives.

  • Dust Impact

  Dust not only reduces visibility in the work area and increases equipment wear, but may also enter the human body through the respiratory system, affecting employee health. In addition, untreated dust may also drift into the surrounding environment, causing pollution to air quality.

  Dust Treatment Plan

  • Source Control

  Choose low dust raw materials

  When purchasing raw materials, priority should be given to selecting low dust stone, sand, cement, etc.

  • Wet operation

  Wet operation is used in crushing, screening and other processes to reduce the generation of dust by spraying water.

  • Enclosed operation

  Enclose equipment that is prone to generating dust to reduce dust leakage.

  Dust removal equipment

  • Bag filter

  Set up a bag filter in key areas of the mixing plant to capture the generated dust.

  • Electrostatic precipitator

  Using an electrostatic field to charge the dust and adsorb it onto the dust collection plate, achieving the dust removal effect.

  • Cyclone dust collector

  Uses centrifugal force to separate the dust in the dusty gas, achieving the purpose of dust removal.

  Dust conveying and storage

  • Closed conveying 

  Using sealed conveying pipelines and vehicles to prevent dust from overflowing during the conveying process.

  • Sealed storage

  Seal and store materials that are prone to generating dust, such as cement and additives, to reduce the loss of dust.

  Dust Utilization And Recovery

  • Recycling and reuse

  Conduct quality testing on the collected dust, and those that meet the requirements can be recycled and reused to reduce production costs.

  • Disposal

  Harmless treatment of irrecoverable dust to prevent environmental pollution.
  Monitoring and Control

  • Installing a dust concentration monitor

  Real time monitoring of the dust concentration inside the mixing plant to ensure that the dust concentration is within a safe range.

  • Establish a monitoring system

  Real time monitoring of the operation status of dust removal equipment to ensure normal operation, timely detection and handling of faults.

  Conclusion

  The dust treatment plan for concrete mixing plants needs to start from multiple aspects such as source control, dust removal equipment, dust transportation and storage, dust utilization and recovery, as well as monitoring and control. By implementing effective dust treatment plans, the dust concentration inside the mixing plant can be significantly reduced, the working environment can be improved, employee health can be guaranteed, and environmental pollution can be reduced.
