Why dense phase?
By definition, dense phase pneumatic conveying simply means using a small amount of air to move a large amount of bulk material In closely associated slugs through a conveying line, much like extruding. Unlike dilute phase conveying systems that typically use larger amounts of air to move relatively small amounts of material at high velocities in suspension, dense phase offers the enormous advantage of efficiently
pushing a much denser concentration of bulk solids at relatively low velocities through a conveying line.
