There are a few things that should be considered if you will be filling a silo from multiple sources:
- Will both sources be used simultaneously? This will affect bin vent filter sizing.
- Will a multiple sources provide an un-even silo fill? This will either affect silo structural design or fill line/target box location.
- Will there be backflow along an unused fill line? Some measure will need to be taken to prevent product from exiting via an unused fill line. This can be as simple as a cap on the line or as complicated as an automatic valve.
