Bins and Hoppers for Bulk Solids

Johansoris definitions of terms used to characterize solid particles are given in Section 1.6.4. Related topics include mixing of solids. Section 7.4 and transportation of solids. Section 2.6. The important terms are AI, RI, HI, FRI, FDI, BDI, Cl, RAS and SBI. 

Promote mass flow with cone angle to the vertical related to the wall friction angle of the solid. 

Cone angle with the vertical (°) Wedge angle with the vertical (°) less than less than 

Design hopper prevent ratholing with hopper angle (with the vertical) HI -r 3°. 

Diamondback hopper tends to prevent bridging and ratholing.
