| 目的 实现球磨室在常压下的大面积介质阻挡放电等离子体，开发出商用等离子球磨机。方法 通过在不同弹簧和平台质量条件下，利用振动传感器测试平台的振幅（峰峰值）和加速度（有效值）数值，对比确定最优配置和机械振动参数。结果 当振动平台振幅接近球磨室内径时，获得高振幅和高加速度的磨球，显著缩短了气体放电间距，实现了球磨室在常压下的大面积介质阻挡放电等离子体。所设计的单筒等离子振动球磨机，其振动平台可选用φ7 mm、φ8 mm两组弹簧，根据平台质量的不同，选择不同类型的激振块组合，可以在30 Hz转速以上实现平台振幅峰峰值达到或者接近球磨罐内径值，同时拥有10g以上的加速度有效值。结论 本试验综合机械振动学、高压绝缘放电和材料加工技术，所研制的等离子体球磨机实现了机械能和等离子体能在球磨过程中的协同作用，显著提高了粉末活性，降低了化合物合成反应激活能，从而显著提高了所制备材料的性能。 |

| Objective To achieve a large area dielectric barrier discharge plasma in ball mill chamber under atmospheric pressure, and develop commercial plasma ball mill. Methods The vibration sensors were used to test the amplitude (peak peak value) and acceleration (effective value) of the platform under the conditions of different springs and weights of platform to de-termine the optimal configuration and the mechanical vibration parameters. Results When the amplitude of the vibration platform was close to the inner diameter of the ball milling chamber, a combination of the high amplitude and high speed ball could significantly reduce the gas discharge distance, which obtained a large area dielectric barrier discharge plasma in ball mill chamber under atmospheric pressure. The vibration platform of the designed plasma assisted vibration ball mill with single cylinder structure could choose two groups of springs, i.e.φ7 mm andφ8 mm. Different exciting blocks could be selected according to the different weights of the vibration platform. Under this condition, the peak amplitude of the platform could reach or approach the inner diameter of the ball mill tank at a speed of more than 30 Hz, and the platform had an acceleration effective value of more than 10g. Conclusion This test combines mechanical vibration science, high voltage insulation discharge and material processing technology. The synergistic effect of mechanical energy and plasma energy is produced by the developed plasma ball mill, which can effectively promote the powder activation, decrease the activation energy of compound synthesis reaction, and thus significantly improve the properties of the prepared materials. |
