Feb 17, 2018 The empirical approach to grinding modelling and control presents also some implementation difficulties. First of all since the process model unavoidly changes with time, it must be estimated by adaptive methods such as it is in self-tuning controllers. Second the MV controller requires the knowledge of the
The simulator implements the dynamic ball mill grinding model which formulates the dynamic responses of the process variables and the product particle size distribution to disturbances and control
Figure 2. Ball Mill Grinding Circuit The ball mill is in closed circuit with a sump and three cyclone classifiers. The ore and trim water are added to the ball mill and the outflow from the ball mill goes to a sump where additional water is added. The slurry from the ball mill is pumped out of a sump into two cyclone separators. The underflow from the
Oct 09, 2017 Grinding in Ball Mills: Modeling and Process Control Grinding in ball mills is an important technological process applied to reduce the size of particles which may have different nature and a wide diversity of physical, mechanical and chemical characteristics Typical examples are the various ores, minerals, limestone, etc The applications of ball mills are ubiquitous in mineral
