Hopper Design Principles - Chemical Engineering | Page 1

The first step to achieving mass flow is to ensure that the converging walls are steep enough, and have friction low enough, to allow the bulk materials to slide along them. This is accomplished by first testing the material to measure wall friction, and then calculating the minimum hopper angle that will allow mass flow. Hopper angle for mass flow
