The flow rate from massflow bins depends on the hopper geometry the wall lining material and the flow properties of the bulk solid. However for a well designed massflow bin the discharge is uniform and the flow rate predictable. To illustrate the influence of massflow hopper geometry on the potential unrestricted flow rate consider

Numerical simulation of particle flow behavior in a screw

The mass flow rate was directly proportional to the screw rotating speed from 200 to 1000 rpm which indicates that increasing the screw rotating speed is an effective method to improve the transport capacity of a screw conveyor at a low screw rotating speed. This method is not effective once the screw rotating speed exceeds a certain value.
