| Abstract: |
| The EDEM discrete element software was used to simulate the collision of steel balls and materials in the grinding chamber when the horizontal high-energy ball milling equipment was used to prepare the nano SiO2 powder. Through the use of practical experiments, nano SiO2 powders have been successfully prepared. Combining the results of the simulation with the actual experiments, we obtained a set of mature processes for preparing nano SiO2 powders. That is, in the case of a blade length of 115 mm, a width of 8 mm, a rotation speed of 1000 rpm to 1100 rpm, a steel ball diameter of 3 mm, and a ball material ratio of 15:1, nano SiO2 powder can be obtained by ball milling using a horizontal high-energy stirring mill for90 min. |
