Hopper Design Principles
A mass flow screw feeder, comprised of a tapered section followed by a section with increasing pitch, ensures that the capacity of the feeder increases in the direction of flow (see Figure 13) The length of the cone and the pitch schedule are chosen such that the capacity of the screw increases linearly along the hopper length...

Conveyor Capacity
Conveyor capacity is determined by the belt speed, width and the angle of the belt  and can be expressed as Q = ρ A v (1) where Q = conveyor capacity (kg/s, lb/s) ρ = density of transported material (kg/m 3, lb/ft 3) A = crosssectional area of the bulk solid on the belt (m 2, ft 2)...
