'Chem-jet' Dust Suppression System is designed to add a controlled amount of water, with a patented wetting agent (Compound MST*) at application points to precondition the material and reduce the level of dust escaping into the atmosphere during operation. The fundamental philosophy is to suppress the dust before it becomes airborne which makes it a preventive form of Dust Control. The treatment is effected upon the material by spraying a finely atomized mist at strategic points by specially designed through a network of piping, pumping unit, dosing unit and flow control devices. Moisture addition is typically 0.5-1.5% depending upon the application.
