破碎和磨矿的主要成本是动力消耗。它可占生产成本的50%。改善车间的操作可使动力消耗(KWh/t)降低15%。这些改善是通过磨矿效率的最优化和使用专家模型控制系统实现的。最优化就是要确定关键操作条件的水平,便得磨机中矿石的磨矿效率最高,这些最佳水平是通过工业(实验室)试验和使用先进作业模型进行计算机模拟来确定的。专家模型控制通过一个最佳的在线测量仪鉴别磨机中矿石的性质,从而调整磨矿环路,使其性能达到最佳。根据这些信息,控制系统动态地确定操作点,使系统性能最佳。本文中列出了磨矿环路最优化和模型控制的两个工业应用的实例,以证明这项新技术的力量。
The main cost of crushing and grinding is power consumption. It can account for 50% of production costs. Improve workshop operation can reduce power consumption (KWh / t) by 15%. These improvements are achieved through the optimization of grinding efficiency and the use of expert model control systems. The optimization is to determine the level of critical operating conditions so that the grinding efficiency of the ores in the mill is highest, as determined by industrial (laboratory) tests and computer simulations using advanced job models. Expert Model Control Identifies the nature of the ore in a mill with an optimal on-line gauge to tune the grinding loop for optimum performance. Based on this information, the control system dynamically determines the operating point for optimal system performance. This article lists two examples of industrial applications for grinding loop optimization and model control to demonstrate the power of this new technology.
