Abstract:
In a material handling system in which a chemical treatment and water are added to a bulk solid, a method and apparatus for minimizing the amount of moisture added to the bulk solid while effectively controlling dust in the system. A moisture analyzing means monitors the surface moisture level of the bulk solid, and a calibration/measuring means determines the proper amount of chemical and water to be fed to the system for dust control. There are associated means for feeding the chemical treatment and water to the bulk solid, and a dust analyzing means, which monitors dust levels in the system and sends an electrical signal to the calibration/measuring means in order to adjust chemical feed and water flow in the system.
