  OPERATIONAL OPTIONS FOR DUST CONTROL

  Crushed coal from the crushing station will contain a higher fraction of fine particulate and typically requires a ducted dust collection system. Conveyor transfers into the tripper room area will usually have dust collection hoods, and may also use secondary dust control systems such as fog spray systems. See Figure 2. Typical Dusting Complaints Dust will be present at many loions through ...

  Development of a dust minimization system for the coal wagon .

  A wide range of particle sizes is produced during dust generation. Coal dust is produced during coal processing. The amount of coal dust produced is measured in microns. Coal dust particles ranges in diameter from 10µm to 75µm. Particles with small diameter takes a long time in air before settling down to the ground. In the coal handling plant, coal dust is generated through cola crushing ...
