摘　　要：磨矿介质运动状态对矿石的解离度以及后续选矿指标影响非常大,本文从磨矿介质性质、介质与衬板关系、磨矿介质制度、数值模拟四个方面介绍了中外学者在磨矿介质运动规律方面的现状与进展。现有的研究表明,介质的运动状态规律受到磨机的运行操作参数的影响,不同的介质形状、介质级配、球磨机转速、介质的充填率等因素都会改变介质的受力方式和大小,进而影响影响磨矿介质运动状态,另外,矿石性质(矿石泥化、矿物组成、粘度等)对介质的运动状态也有一定程度的影响。根据现有的理论研究现状和实际存在的问题,磨矿介质运动状态的规律研究将是未来发展的一个重要方向。The movement state of the grinding medium has a great influence on the degree of dissociation of the ore and the subsequent mineral processing indexes.Chinese and foreign scholars have a lot of research in the four aspects of the nature of the grinding medium,the relationship between the medium and the liner,the system of the grinding medium and the numerical simulation.These studies have shown that the law of the media's motion state is affected by the operating parameters of the mill.Different media shapes,media gradations,ball mill speed,media filling rate and other factors will change the force mode and size of the media,thereby affecting the movement of the grinding media State,in addition,the properties of the ore(ore muddy,mineral composition,viscosity,etc.)also have a certain degree of influence on the movement state of the medium.According to the current theoretical research status and actual problems,the research on the law of the movement state of the grinding media will be an important direction for future development.
