Hopper Design Principles - Chemical Engineering | Page 1

Jan 01, 2016· 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 ...

Ten Steps to an Effective Bin Design - AIChE

determine an appropriate outlet size and feeder. Keep in mind that the mass-flow bin design process is iterative. The actual outlet size will depend on the required discharge rate from the bin and the feeder selected. These factors, in turn, affect the slope and shape of the mass-flow hopper wall, as discussed in the next section. Step 6.

Bulk Storage Hopper Flow & Feeder

The extra capacity afforded by a 'V' shaped hopper also extends the residence time of the hopper contents. Processes that improve de-aeration also favour a more uniform discharge density of the hopper contents, which may be an asset on feed control, filling and packaging application for product that are filled by volume and sold by weight.

Retrofitting bins, hoppers, and feeders to solve flow problems

A bulk solids feeder must draw material uniformly across the entire hopper outlet to ensure mass flow. A poorly designed feeder or partially opened gate valve can effectively reduce the hopper outlet size, resulting in funnel-flow problems regardless of the hopper design. In many cases, retrofitting the screw, belt, or rotary valve
