Service Life of Dense Phase Pneumatic Conveying
[P3674] Mactenn 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 8m horizontal and 30m vertical. The system is a 228 liter Maxflo with a 125mm pipe line 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, new filling Inflatek® Valve and air manifold. The vessel and pipe line remain originals and are in very good condition expected to offer many more years of service. The pipe line, bends, and vessel are made from stainless steel 304 with all external surfaces coated in a corrosive resistant clear lacquer.
