Design a silo / hopper in order to ensure a good flow; Estimate the discharge rate of a silo / hopper; Take action in case of flow problems; Note that the way a powder is flowing is depending on its properties. General powder properties, including flow properties, are listed in this page : Powder Properties.
high powder flow rates without the potential for severe flushing. Such a system can replace air lost when a powder compresses, and thereby prevent an inrush of air from the outlet that could impede flow The small amount of air needed to fill voids and increase the flow rate ten or more times is not enough to create dust or fluidization.

Pneumatic conveying systems are flexible in terms of rerouting and expansion. A pneumatic system can convey a product at any place a pipeline can run. There are several methods of transporting materials using pneumatic conveying. In general, they seem to fall into these main categories: dilute phase, dense phase, and semi-dense phase.
Additionally, cement silo walls can create more clogging issues than their steel counterparts, and moisture in the air can also dampen the material, causing clogging. One of the best ways to help prevent lost storage capacity is to schedule regular silo inspections. Mole•Master™ can fully examine power house silos, pack house silos, pre-heater towers, raw meal silos, kiln feed silos, conditioning towers, and more, detecting any problems within the silo or in the structure of the silo …

culverts to pass the 100-year flow 3. Bottomless culverts with footings should be designed to pass the 100-year flow with the headwater less than the top of the culvert. The 25-year should allow 1 foot of freeboard for debris flow. 4. Headwater to culvert diameter (HW/D) should be less than or equal to 1.25 though it can be up to 3 to 5 if
