Hopper Design Principles - Chemical Engineering |

δ. φ. Jenike [1] found that the hopper angle required to allow flow along the walls depends on the friction between the powder and the walls, the friction between powder particles, and the geometry of the hopper.Design charts originally developed by Jenike [1] provide allowable hopper angles for mass flow, given values of the wall friction angle and the effective angle of internal friction ...

A Brief History of Coal Hoppers – Appalachian

In the 1890s, the typical coal car was either a hopper-bottom gondola (flat floors over the trucks) or full-blown hopper cars with sloping floors and horizontal drop doors under the center sill. Sawtooth-style hoppers came into somewhat common use in that decade, with the 35-ton Pennsy GG of 1895 combining the sawtooth hoppers and a sloped floor.

Two extremes of hopper shape are presented a conical hopper and plane or wedge shape hopper. The latter gives mass-flow at larger half angles because material converges in only one direction rather than two for a cone. Fig 2.
