Cotton dust may contain many substances including ground-up plant matter, fiber, bacteria, fungi, soil, pesticides, non-cotton matter, and other contaminants that may have accumulated during growing, harvesting, and subsequent processing or storage periods.
LOW VELOCITY DUST CONTROL ABSTRACT Two types dust control systems are utilized in the mining industry. Most familiar is the high velocity design, where air velocities in the ductwork are in the range of 3,000 to 4,000 feet per minute (FPM). The other design is the low velocity system, where transport velocities are less than 1,800 FPM.
