Most degradation and wear occur primarily at the end of the conveying cycle, where the conveying velocities are always the highest. The HDP 4000 Full Line Concept system prevents the conveying line from purging or emptying at the end of the cycle by precisely controlling the supply air pressure and volume at the transport vessel and utilizing the DC-5 Air Saver controls along the conveying line. Almost any conveying velocity, even down to 50 ft/min, is now achievable. Fragile and abrasive materials such as carbon black can be conveyed at velocities below 100 ft/min, resulting in only minimal degradation and/or wear.
