Re: Flow Function Data For Cement.
Normally cement ‘s fluidising properties are exploited when it comes to silo discharge. Few aeration pads on the right position on the silo cone and cement will come out of a 2” opening.
If you want to go the scientific way cement silos should be designed for mass flow due to deleterious nature of cement. You should be looking for mass flow rather then rathole diameter. Wall friction on carbon steel is normally between 25-30 degrees and effective angle of friction is between 40-50 degrees. These are just generic valves do get you sample tested for silo design purposes. ■

Flow Function Data for Cement.
Ladies and Gents,
I am trying to establish the minimum opening for a cone exit of a cement Silo Hopper. This is the first time I am doing this and require this information to establish the intersection of the Flow Factor curve and the Flow Function curve which will give me my critical stress level to establish my arching condition (should there be one). Although we have been making silo's for many years the companu does not seem to have historical data on this subject. Any help will be appreciated.
Many thanks and kindest regards
Christian. ■
