Low-pressure pneumatic conveying system

LOW-PRESSURE CONVEYING SYSTEMS 1.Cyclic process System (closed circuler pipeline) without separator: Recommended for smaller material quantifies and shorter conveying distances. The exhaust air is re-used as conveying air. The advantages of this design lie in its low investment costs, lack of exhaust air and, therefore, absence of a filter, with material being injected directly into the silo or container. Decoupling is required for safety reasons. 2.Cyclic process System (closed circular pipeline); cyclone and rotary valve: This System is used for larger material quantifies and short conveying distances. It offers the same advantages as those listed above. This System is also decoupled by means of the rotary valve. 3. Filtering separator: The most economical System for large material quantifies and long conveying distances. The separator can take the form of either a silo installation filter with a housing strength that is able to withstand the internai pressure of the silo or a bag filter with a rotary valve for decoupling. While the first variant offers the advantage of low investment costs despite the drawback of overpressure in the silo, the second variant offers decoupled material discharge and neutral pressure conditions in the silo.
