  8. 8. Particle Size “ A ton/hour drier will have about 8.3 kg (18.3 lb) of airborne powder, and if it has a mean diameter of 120 microns it will have a total surface area of 417 m 2 (4,503 ft 2 ). Similarly, 10 ton/hour drier will have 4,170 m 2 (45,033 ft 2 ) total surface area. “ Amazingly, over an acre! Excerpt from Principles, Prevention, Detection, and Control by Dr. Chris Bloore
