| Abstract: | The group settling of non-uniform grains is a very widespread phenomenon in nature, so a series of analysis on experimental method of it has been carried out in this paper. By comparing the methods of settling experiment and fiuidization experiment, it can be considered that the method of fluidization experiment by sampling in cone - shaped tube is a better one at present. |
