Inverted cone silo design is mainly used for large storage silos in the cement industry and other mineral industries for cement, raw meal, fly ash, ground granulated blast furnace slag, alumina and similar products.

The material discharge is for fluidslide system.

The design criteria is stated in the Eurocode EN 1991-4, or the relevant national codes such as the DIN EN 1991-4 (2005) and DIN 1055-6. They can all be found in our forum.
All common silo codes including the new Eurocode EN 1991-4 predict the same fill pressures from concentric filling and use the Jansen formula, in which the horizontal pressures increase with the height from the silo top to the bottom, based on an e-function and with the silo diameter, the wall friction coefficient, the material specific weight and the horizontal pressure ratio as the main parameters.

See post above (Book about bulk material storage) to find the Jansen formula.

Hope it's a help and good start point for you

regards

Dell Brett
