1.3.3 Conveying Air Velocity For dilute phase conveying a relatively high value of conveying air velocity must be maintained. This is typically in the region of 2400 ft/min for a very fine pow-der, to 3200 ft/min for a fine granular material, and beyond for larger particles and higher density materials. For dense phase conveying, air velocities ...

Pneumatic Conveying is a cost- and energy-efficient method of transporting dry bulk materials such as powders and granules from one place to another. A typical example of a pneumatic conveying system that we engineer and manufacture involves conveying a material (such as polymer, lime, soda ash, plastic pellets/powder, dry milk etc.) from a ...

Nov 17, 2015 Conveyor manufacturers must know whether the system requires sanitary design, using 316L stainless steel, or if 304 stainless steel or carbon steel will suffice. In pneumatic conveying systems, all equipment must complement each other. If one piece of equipment is too large or too small, it will keep the system from working properly.
