LDP 4000 is a dilute phase, medium-velocity, low-pressure, continuous conveying system. The product is generally used for conveying low to high density materials, as well as abrasive and non-abrasive materials, in case degradation of the conveyed material is a concern. Examples include coffee and pinto beans, fine chemicals, flour, grain, sugar, salt, plastic pellets and malt. The typical conveying velocities are normally at 10m/sec (2,000 feet per minute), while the conveying pressure can reach an impressive 15psig (1barg).
The concept makes use of a rotary airlock feeder, controlling the feed rate to the conveying line. The DC-5 Air Saver technology can be used for minimizing and optimizing the low pressure supply, which is supplied by a low pressure positive displacement blower.
