Determining Discharge Rates of Particulate Solids

The flow pattern (velocity gradients and dead zones) and stresses within the bulk material during discharge from a silo, bin, or hopper depend on friction between the particles (internal friction), friction between the particles and the wall (wall friction), and the inclination of the converging section (hopper half-angle).

Bulk solids basics: Flowability

The simple definition of flowability is the ability of a bulk solid to flow. But there is a scale between free flowing and non-flowing. Further, the flowability is not an inherent material property. Rather, it is the result of material physical properties and/or the equipment that is used for handling, storing and processing.

How Wall Friction Affects Hopper Angles

What is wrong with this statement? Mass flow is dependent on wall friction properties and is affected by the smoothness and steepness of the hopper wall and the properties of the bulk material. If you design your hopper for 70°, it may achieve mass flow; but, it may flow in mass flow at a shallower angle say, 65° or may also require 85°.

Storage Silos 101

The field of bulk solids handling was developed due mainly to the work of Dr. Andrew W. Jenike, who pioneered the theory of bulk solids flow at the University of Utah in Salt Lake City. Jenike's approach requires two important considerations: Flow properties testing on the bulk solid to be handled, along with proper silo and feeder design.
