Simulation Experimental Research on the Agitator of a Horizontal Four Axis Stirring Mill
At present,the research on stirring mill at home and abroad is still stuck in the single-shaft stirring mill,which has the shortcomings of small size and low output.Therefore,the horizontal four-shaft stirred mill agitator was studied to improve the output and grinding efficiency.In the actual grinding process,it is difficult to directly analyze the movement state of the medium inside the stirred mill,so the collision characteristics of the medium in the stirred mill are studied by using EDEM discrete element simulation software,and the effects of forward rotation and diagonal reversal of the stirred mill on the movement speed of the medium in the stirred mill and the number of collisions between the media are obtained.The influence of forward rotation and dislocation phase rotation of agitator on the movement speed of the medium,the number of collisions between the media,and the average collision energy in the stirred mill.The results show that the velocity of the forward rotation medium is larger than that of the diagonally reversed medium,but the move-ment of the diagonally reversed medium is more intense and the number of collisions is more.The velocity of the medium of the dislocation phase rotation is greater than the velocity of the medium of the forward rotation,and the total collision energy of the medium is greater than the total collision energy of the medium of the forward rotation.These two sets of simulation results reveal the influence of different rotation modes on the motion characteristics of the grinding medium,deepen the understanding of the grinding process,and provide theoretical support for subsequent equipment optimization and process innovation.
