Application of model predictive control in ball mill grinding circuit

WebClosed circuits return a certain amount of the ball mill’s output back to the ball mill for further size reduction. A typical closed system grinds the ore between two to three times. Hydro-cyclones installed directly after the ball mill ensure only over-sized material is returned to the ball mill. WebAs for any output, ball mill circuit output is a function of both its inputs and efficiencies. There are two "inputs" to a ball mill circuit: the ore fed to the circuit and the power delivered by the grinding mill. A ball mill circuit has two "efficiencies": that of the ball mill grinding environment* and that of the classification system*. A ... hon series 38000

WebSep 1, 2007 · Ball mill grinding circuit is essentially a multi-input–multi-output (MIMO) system with strong coupling among process variables. Simplified model with multi-loop decoupled PID control usually cannot maintain a long-time stable control in real practice. Web3.1 System Modeling Mathematical Modeling In designing control systems we must be able to model engineered system dynamics. The model of a dynamic system is a set of equations (differential equations) that represents the dynamics of the system using physics laws. The model permits to study system transients and steady state performance.
