Development of a dust minimization system for the coal

Development Of A Dust Minimization System For The Coal

The amount of coal dust produced is measured in microns. Coal dust particles ranges in diameter from 10 m to 75 m. 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 and grinding when coal is unloaded, transferred
