Two dense-phase pneumatic conveying systems were supplied to handle 31751.5 kg per hour of Fish Food Pellets over a distance of 80.772 meters horizontal and 27.432 meters vertical. The systems were 0.849505 cubic meter vessels with a 254 mm pipe line. Both systems were located under a feed hopper with start and stop controlled in automatic mode by the feed hopper and silo reception level probes.
The systems are working very reliably with no line blockages and exceed the customer’s expectations regarding transfer rate providing 40 tons per hour for large fish food pellets and over 45359.2 kg per hour for the smaller pellets. Material degradation was a key concern with a requirement of 0.6% maximum degradation. The pneumatic conveying systems easily achieved their objectives with an average material transfer velocity of between 2.4384 meters per second and 2.7432 meters per second. The pipe line conveying pressure was between 12 psi and 13.5 psi. These particular systems incorporated multiple manifold settings allowing the transfer of a wide range of products materials and sizes.
