通过有效的控制来提高磁选过程的精矿回收率可以提升磁选机的整体工作性能。围绕提升悬浮式干式磁选机精矿回收率,在模型预测控制理论(MPC)的基础之上,设计出了一种通过滚动优化的方式来对磁选过程进行优化控制的系统,实验表明:在悬浮式干式磁选机控制系统中采用模型预测控制的方法比传统的控制方法得到的精矿回收率提升了3个百分点,对实现高效率磁选的发展奠定了重要基础。 Through the effective control to improve the magnetic separation process of concentrate recovery can improve the overall performance of the magnetic separator. On the basis of model predictive control theory (MPC), a system of optimizing the control of magnetic separation process by means of rolling optimization was designed around improving the recovery rate of concentrates of suspended dry magnetic separator. Experiments show that : The method of model predictive control in the suspension dry magnetic separator control system improves the recovery rate of concentrate by 3% compared with the traditional control method, laying an important foundation for the development of high efficiency magnetic separation.
