| Abstract: | This subject is about study the 3-dimensional simulation of gas flow field in crash cavity , the center region of hammer mill .In the process of simulation , the crash cavity of grinder is taken for research object .The 3-dimentional model is built in UG and meshed in Gambit .The meshed file is imported into FLUENT to do analysis and the characteris-tic distribution of negative pressure and motion .Characteristics of air pressure and motion in the smashing region of new-type hammer mill are the major research contents in this subject .And the research of flow field of the center region builds the theory foundation for further optimal designing and improving the sieving efficiency of this new -type hammer mill. |
