提高低温拜耳法矿浆磨整体设备效率的探索与实践

本文从影响矿浆磨设备整体效率(OEE)的可用性、性能和质量方面入手对现有低温拜耳法矿浆磨整体效率的现状、存在问题进行了系统分析。重点从磨机级配、进出料系统、旋流器等方面进行了优化分析设计和改进实施。改进后氧化铝厂矿浆磨整体效率由最初的34%提高到了60%。

氧化铝矿浆磨节能技术改造

本文主要研究了氧化铝生产中的矿浆制备系统,通过一系列措施优化矿浆磨结构和系统配置达到节能降耗的目的。通过优化磨体内隔仓板结构,提高磨机过料能力,解决矿浆磨满磨现象;通过优化磨机内研磨体填充率及级配,提高磨机破碎和研磨性能,做到降耗增效;同时通过优化矿浆辅机旋流器结构,采用先进的进料方式提高分级效果,使矿浆在较粗的粒度下也有较好的溶出率。

拜耳法矿浆高效旋流分级技术应用

在原有一段磨闭路磨矿流程基础上,通过改进矿浆磨加水力旋流器磨矿新工艺,实现拜耳法原矿浆制备的高效、低耗。一方面矿浆粒度指标合格率由改造前的65%提高至95%以上,确保了后续溶出效果;另一方面大幅提高矿浆磨生产效率,减少了清检、维护工作量。

Reasonable Ball Size of Ball Mill for Preparing Coal Water Fuel and Forecasting Productive Capacity

By using the matrix theory, a 5 parameter grinding mathematical model is established. Based on the properties of feed coal and requirements for size distribution of final product, the model gives the required grinding probability for various particles and corresponding ball size distribution. By using this model, 3 different sizes of ball mill are designed and put into commercial use for coal water fuel. The forecasted ball mill capacity, the particle sizes and particle size distribution as well as the coal water fuel quality parameters are all in line with industrial operation results, which have proved the suitability of the model.
