Dilute phase conveying systems offer an alternative to mechanical conveying systems such as screw conveyors, belt conveyors or bucket elevators.
Dense phase pneumatic conveying is a method for moving difficult, heavy (normally greater than 50-60 lb/cu ft) abrasive, mixed batch, or friable materials at a low product velocity. The system incorporates low gas volume at high pressure, conveying materials through an enclosed pipe in slug form at a controlled product velocity.
Dense phase conveying has enumerated benefits for many processors, and similarly to any value-added technology, those benefits arrive at a cost.
