Loading Spouts Handling Flour

April 9, 2019
Flour Mill, Texas, USA
Two Vortex Loading Spouts receive materials via air-slide conveyors. The remaining six spouts are mounted below bulk bins, which also feature fluidized bin discharges. Any dusts generated during the loading process are collected at a central aspiration system.

In 2016, Vortex was approached by a systems group at the IAOM Conference & Expo. A flour mill in Texas, USA had contacted the systems group to consider adding Vortex Loading Spouts to their loadout station. Engineers from Vortex and the systems group discussed the project on multiple occasions throughout the week. Once back in the office, the engineers continued to collaborate until they were able to identify a solution:

Vertical Travel:

  • (Qty. 2) 10 ft | 3 m
  • (Qty. 6) 7 ft | 2 m

Outlet Scavenger Size: 20 in | 510 mm (diameter)

Load Rate Capacity: Up to 250 ftᶾ/min (CFM) | 245 mᶾ/h (CMH)


  • Explosion-proof design.
