Estimation of solids flow rate

The mass flow rate or throughput of the bulk material can be estimated if the net transport velocity, trough and material geometry and bulk density are known. Assuming the displacement equation (6.12) holds, then the horizontal velocity can be written as  

The average transport velocity of the bulk solid can then be estimated by a general expression  

This efficiency of transport term is a function of the conveying conditions through two equipment terms, the dynamic material coefficient (F) and the vibration angle ((3), as well as material-dependent terms. The material dependence will be based on wall and internal friction, material shear strength or cohesion, particle size and density and almost 

The mass flow rate or throughput of the conveyor can be estimated by
