More### Optimal control for continuous bauxite grinding

Considering the reduction of power consumption of ball-mill,we propose a multi-objective multi-model predictive control for the continuous grinding process of bauxite with bauxite ores coming from different mine sources and with different qualities.In this method,we first build the state-space concentration-predictive model and the finenessprediction model based on the weighted multi-model of size-mass balance;and then,we develop

More### Ball Mills - an overview ScienceDirect Topics

The ball mill is a cylindrical drum (or cylindrical conical) turning around its horizontal axis. It is partially filled with grinding bodies: cast iron or steel balls, or even flint (silica) or porcelain bearings. Spaces between balls or bearings are occupied by the load to be milled.
