Summary:The flow properties of the start, stop, fluctuation and other unsteady flow stage are very important for high concentration slurry transportation. This text will analyse the change rule of the resistance, velocity and flow plug of high concentration slurry, as well as derive three equations for calculating the minimum driving pressure, the Average pressure loss and the stopping time under the viewpoint of dynamics. This model can effectively predict the average pressure loss and the stopping time. This text can also provide a reference for designer about the efficiency reliability of paste conveying system as well as pipe block problem caused by driving force.
