Discrete element method can be used to predict the motion of the contents, which are grinding balls and material particles, and estimate the collision force between the balls and the mill wall.A finite element method vibration analysis is performed to calculate the time history response of the vibration from the estimated collision force by dem.
Finally, the finite element model of the bionic ball-end milling cutter was established to study the equivalent stress state of the workpiece under different bionic structure types, and the influence of bionic structure on the cutting force was analyzed.
In this paper, the 3.813m centre drive ball mill is studied.After predigested the rotator with its mean characters, the fem model of the rotator is established.After loading and solving to the rotator with fem software ansys, the former ten modal natural frequencies and vibration modes are got.Through the modal analysis, the position which may be easily destroyed is found.
Then the simulation model of ball mill shell is established.The rotating velocity of the mill in cascading or cataracting is determined and import to software.The different states of media motion can be analyzed by pfc model as shown in fig.Comparing with the motion states figure of laboratory ball mill, the analysis of simulation.
