1、 摘要摘要球磨机是用来粉碎已碎物料的关键设备。它广泛应用于水泥，建筑材料、耐火材料、化肥、金属选矿以及玻璃陶瓷等各种生产行业，对各种尺寸矿石和可磨性物料进行干式或者湿式粉磨加工。球磨机广泛运用于粉磨矿石及其它各种物料，现在被广泛用于选矿，建材及化工等行业。通过对工业实践采集数据振动加速度信号，进行历史趋势曲线设计和实现。振动信号 EEMD 分解 IMFS 曲线显示，磨机负荷参数预报开发。准确的通过数据分析判断球磨机的工作状态。由于选矿生产过程具有非线性、多变量、时变性、大滞后、强耦合的特点，精矿品位等生产指标不能在线测量，致使选矿工程师不能实时调整整个生产过程，这引起研究人员对选矿生产指标预报
2、算法的研究。算法应用到工业现场需要软件平台的支撑，但是国内外针对选矿生产指标预测软件的研发相对较少，虽然算法研究人员也会根据自己的需求开发预测软件，但是这些软件的人机交互性能友好性、易用性较差，通常难以满足其他算法研究人员。为了能为算法研究人员提供功能更强的实用性。本系统采用 MATLAB 与 Java 混合编程技术开发，Matlab 提供基础的函数工具，Java 具有使用方便，可移植性强的优点，并调用生成数据。可用于磨矿过程的监测，保证磨矿过程的安全平稳生产，高效的提高磨矿对提高效率和质量，对节能减排符合世界发展趋势。关键词：关键词：球磨机；Imfs； EEMD；Java； MATLAB；混
