Denseveyor installed below a feed hopper
[P3674] Macawber Group Installation Case Study:
Sodium Bicarbonate Conveying system, Northwich, UK.
In brief:
The dense phase pneumatic conveying system was supplied to convey 14 t/h of sodium bicarbonate over a distance of 26 ft. horizontal and 98 ft. vertical. The system is an 8 cubic feet Denseveyor® with a 5” pipeline and is located under a feed hopper with start and stop controlled in automatic by the feed hopper and silo reception level probes. The system was first installed in November 1996. In July 2014 after 17 years of continuous daily operation, it was upgraded with a touch screen operator interface, a new filling Dome Valve, and air manifold. The vessel and pipeline remain originals and are in the very good condition expected to offer many more years of service. The pipeline, bends, and vessel are made from stainless steel 304 with all external surfaces coated in a corrosive resistant clear lacquer.
