Get PriceA rise in air flow to the silo occurs when the density of the fluidised powder is reduced, especially at the end of delivery. This transition stage is short, but could result in a catastrophic pressure rise in the silo. The maximum instantaneous flow rate of air may be as high as 3.25m3/s (~6900 cfm) (see Appendix A).
