It is not unusual for a flour mill to have problems with in-line flap diverters installed a pneumatic conveying system. There are several problems inherent in the design, as the soft seals around the flap are exposed to direct blast abrasion from grist or wheat flour. This can create significant pressure drops in the conveying system, as well as line plugs once product is allowed to pass through the closed leg of the diverter.
The client was experiencing these precise hassles with the in-line flap diverters purchased when the mill was built. The product leakage from the diverters was creating cross contamination, conveying inefficiencies, and significant downtime to remove line plugs. In order to address these issues, they installed Vortex 2- and 3-Way Wye Line Diverters, which are ideally designed to overcome common problems associated with in-line flap diverters.
