摘要

高压脉冲破碎技术作为一种新型的破碎技术，在选矿行业中有着广泛的应用前景。现有的研究主要集中在矿石特性和基本放电参数对破碎的影响上，很少考虑电路结构参数和脉冲极性等因素。本文详细讨论了介质击穿模型的发展，强调了建立能准确描述非均质粒子内部放电通道轨迹的模型的重要性。总结了电路结构参数对脉冲波形的影响。讨论了脉冲极性对电击穿的影响。此外，强调了能量依赖因素（电压和脉冲数）对破碎的影响，并认为合理设置这些参数可以提高处理效率。本文综述为HVP技术的优化提供了一些新的见解。

Optimization of discharge parameters for high-voltage pulse crushing technology − A review

High-voltage pulse (HVP) has attracted significant attention as a novel crushing technology and has the potential to be applied in mineral processing industries. The existing studies mainly focused on the effects of ore characteristics and basic discharge parameters on fragmentation and rarely considered factors such as circuit structure parameters and pulse polarity. This paper discusses the development of the dielectric breakdown model in detail and emphasizes the importance of constructing models that accurately describe the trajectories of discharge channels inside heterogeneous particles. The influence of circuit structure parameters on the pulse waveform is summarized. The effect of pulse polarity on the electrical breakdown is also discussed. In addition, the effect of energy-dependent factors (voltage and pulse number) on fragmentation is emphasized, and a reasonable setting of these parameters is believed to enhance processing efficiency. This review offers some new insights into the optimization of HVP technology.
