Study on Wear Degree of Crushing Teeth of Toothed Roll Crusher with Different Installation Elevation Angles
In order to improve the wear resistance of the crushing teeth,according to the characteris-tics of a double-toothed roll crusher,based on the analysis of its performance parameters,a comparative simulation analysis of the influence of different installation elevation angles on the wear degree of the crush-ing teeth was carried out by discrete element soft.The simulation results show that when the hardness of the ore is soft,the installation elevation angle has little effect on the wear resistance of the crushing teeth.When the ore is hard,the installation elevation angle has a great influence on the wear resistance of the crushing teeth.When the installation elevation angle of the crushing tooth is 60°,the maximum crushing total work re-quired for the crushing of the toothed roller is 546.04 W,and the average value is 249.53 W.The most suit-able installation elevation angle of the double-toothed roller crusher is 60°.Through reasonable discrete ele-ment analysis simulation results,it can provide reference for the subsequent optimization upgrading and on-site process layout of the double-toothed roll crusher.
