磨矿介质抛落轨迹预测工具研究与开发

摘要

The grinding media near the cylinder wall of tumbling mills will form the falling motion as the lifter effect.The different impact positions of grinding media will produce different impact energy,which will affect the production and distribution of mineral particles.In order to quantify the internal trajectory of industrial mill grinding media,research and development of grinding media trajectory prediction tool were fulfilled,based on the analysis of the influence factors and theoretical modeling method.The trajectory prediction tool can be used to quickly calculate the drop trajectory of the grinding media under different working conditions,and also to calculate the impact point positions and the impact energy.%位于磨机筒壁附近的磨矿介质会在提升条的作用下在磨机内部形成抛落运动.不同的磨矿介质抛落点会产生不同的冲击能量,从而影响磨机内部矿物产品的产量和颗粒分布.为了量化工业磨机内部磨矿介质的运动轨迹,在分析其影响因素的基础上,通过理论模型建模方法进行磨矿介质抛落轨迹预测工具研究与开发.开发的轨迹预测工具可以快速计算不同工况下的磨矿介质抛落轨迹,并计算冲击点和冲击能量.
