ABB has released the Optimize IT automatic control system for comminution optimisation.
Crushing and grinding, or comminution, is one of the most important steps in extracting minerals from ores. The performance of a minerals plant is dependent on the ability of its comminution plant to produce consistent quality and to be energy efficient.
The system ensures an adequate grain size distribution inside the comminution circuit and provides an optimal balance between the inflow of coarse material and the outflow of product. It offers multivariable control, fuzzy logic, and neural networks techniques.
The optimiser continually monitors the loading of the mill and the flow of material through the system. It can identify situations when the feed to the mill and the output can be increased while maintaining product quality.
Frequent, small changes in the process lead to smooth and stable material flow. This results in better product quality, less plant downtime, and longer equipment life. Consumption of grinding media is also usually reduced.
