| 1 | Some key factors influencing the efficiency of ball milling were discussed in the paper. | |
| 2 | Store the quicklime and gypsum in the tank after crushing and ball milling. | |
| 3 | In addition, this paper also made a research on the milled powder forming technology, and presented some improvement methods. | |
| 4 | Fine-grain doped graphites, which possess excellent thermal-mechanical properties, were prepared by the ball-milling dispersion method. | |
| 5 | The feasibility of using high - energy ball mill to produce nano- sized quartz powder was proved by experiments. |
