Particlesize distribution
The Weibull distribution or Rosin–Rammler distribution is a useful distribution for representing particle size distributions generated by grinding, milling and crushing operations. The loghyperbolic distribution was proposed by Bagnold and BarndorffNielsen [9] to model the particlesize distribution of naturally occurring sediments.

Calculation method to Design Hoppers and Silos
It is important to size properly such feeder, since an undersized feeder can have bad consequences on the way the powder will flow in the hopper, and can turn a mass flow bin into a funnel flow bin. The feeder must be designed to draw out the solid on the entire section of the hopper (which can lead to some overdesign compared to what is actually required for the process).
