The HDP 5000 Full Line Concept Continuous Pressure Conveying System is a dense phase, medium to high pressure, very low to medium velocity, continuous conveying system. It is generally used for conveying medium to high density, heat sensitive, semi-abrasive and/or very abrasive, cohesive, and/or very fragile materials in almost any particle size range over long distances. Examples include finished laundry detergent, silica sand, glass batch granulated sugar, powdered sugar, finished breakfast cereal, coffee beans, plastic pellets, bentonite, cement, starch, silica flour, ball clay, kaolin clay, zinc oxide, pelletized carbon black and alumina.
Typical conveying velocities are generally in the range of 100 to 1000 feet per minute (0.5 m to 5 m/sec) and the conveying pressure up to 100 PSIG (7 barg).
This concept uses two non-fluidizing type pressure vessels which operate alternately to feed material into the conveying line at maximum density. DC-5 Air Saver technology is used to minimize and optimize the high pressure air which is supplied by a high pressure - up to 100 PSIG (7 barg ) - air compressor.
