# dynamic modeling of a mineral ball mill process

### Neural network based control of mineral grinding plants

The dynamic model of the ball mill is based on the description of three particular phenomena [5] l) the mill content mixing, 2) the mill pulp volume variation and 3) the grinding kinetics. Neural network based control 239 The mixing properties are described by a series of two perfect mixers in the case of the ball mill and four in the case of the rod mill.

### Grinding in Ball Mills Modeling and Process Control

The paper presents an overview of the current methodology and practice in modeling and control of the grinding process in industrial ball mills. Basic kinetic and energy models of the grinding process are described and the most commonly used control strategies are analyzed and discussed.

### Model Predictive Control for SAG Milling in Minerals

Model Predictive Control for SAG Milling in Minerals Processing Steven J. McGarel, Rockwell Automation Introduction SAG and ball mills are generally accepted as the largest power consumers in a mining and mineral processing operation and can be 80% of total electrical energy consumed at a specific power consumption of around 20kWh/ton.

### OPTIMIZING THE CONTROL SYSTEM OF CEMENT MILLING

In all cases the dynamics between the process variable and the mill feed flow rate is modelled. The model considers as process variables the power of the recycle elevator or the flow rate of the separator return. The total feedback control loop is demon strated in Figure 2.

### Ball mill

Ball mill. The grinding media is the balls, which may be made of steel ( chrome steel ), stainless steel, ceramic, or rubber. The inner surface of the cylindrical shell is usually lined with an abrasion resistant material such as manganese steel or rubber. Less wear takes place in rubber lined mills.

### New approach to ball mill modelling as a piston flow process

This paper presents a new population balance model (PBM) of ball mills that understands the ball mill process as a hybrid of a perfectly mixed mill and piston flow mill. Usually, PBM for grinding is related to a perfectly mixed mill. In this case, the piston flow was introduced for a more realistic process.

### How Slurry Transport inside a Tumbling Grinding Mills

The discrete element analysis gives sufficiently detailed knowledge of the porous ball charge bed. The next step is to model the flow of water and mineral ore particles of different sizes through the mill i.e., the mass transport of the slurry and solids in the mill.

### Analytical solution for the dynamic model of tumbling mills

Due to the demands for process control, dynamic models for AG/SAG and ball mills have attracted more attention in recent years. Valery Jnr and Morrell [2] proposed a conceptual model to provide accurate dynamic response of mills in terms of power draw, grinding charge level, slurry level and product size distribution to changes in feed rate, feed size, feed hardness and water addition.
