Profile: J.D.B. Dense Flow, Inc. designs and manufactures some high quality dense phase pneumatic conveying systems. The dense flow system is primarily a high pressure, low velocity, dense phase pump for conveying powdered or granular materials. The system can convey a wide variety of materials ranging from abrasive material such as sand and alumina, to corrosive materials like sodium chloride. It can also handle cohesive products like iron oxide. Friable materials such as sulphur coated urea and extruded alumina, can be conveyed just as easily as non-abrasive products like P.V.C or fire extinguisher powder.
