Structure Optimization Design of Rotary Kiln Based on Discrete Element Method
The chemical vapor depositio(CVD)method is the main method to produce silicon carbon cath-odes of lithium-ion batteries in rotary kiln.The structure of rotary kiln influences the granular motion char-acteristics which affecting both coating efficiency and uniformity of particles.In this paper,having the disc rete element method(DEM)used to simulate particle movement,and the particle stacking angle taken as the response value,and HEEDS software based to calibrate the parameters required by DEM simulation,as well as the rotary furnace designed to verify reliability of the parameters.The results show that,the discrete element simulation and experimental results tend to be consistent.The DEM model can be used to analyze particle distribution in the rotary kiln,including having axial variance and height distribution defined as indicators of particle distribution to design rotary kiln's more superior structure.
