Crushing performance analysis of roller crusher based on EDEM
Considering that the R&D and optimization of large-scale mining machinery and equipment need to be based on a large number of experimental data,but the physical research and development not only costs a lot of manpower and material resources,but also has low timeliness,this paper uses EDEM simulation software to analyze the working performance of roller crusher.Firstly,the three-dimensional model of the tooth roller crusher is established by using the three-dimensional modeling software,which is imported into the EDEM software,and the motion parameters of the moving parts are set in the software.Then the particle factory is set up to generate the simulated material,and the particle bond model(BPM)is used to simulate the broken material.Finally,the simulation program is run,the material crushing simulation is carried out,and the operation parameters under different working conditions are obtained.The simulation results show that the output and power will increase with the increase of gear roller speed,but the growth trend of output will slow down.With the increase of tooth roller spacing,the output will increase,but the increase of output is not linear,and the growth rate will slow down first and then increase.The research results of this paper provide a reference for the parameter optimization and selection of roll crusher.
