Plant-wide automation for crushers

November 2013 System Integration & Control Systems Design

Metso delivers first class crushers and equipment for processing aggregates. A crusher for either stationary or mobile use typically comes with an intelligent controller (IC) system, giving it high availability and safe performance. Metso has taken this degree of automation a step further by introducing a plant-wide automation system for controlling and monitoring a full crushing plant consisting of Metso crushers with their IC units. This system, Metso DNA, was first commissioned in 1979. With more than 4500 installations worldwide, Metso has recently expanded the scope for both stationary and mobile crushing plants in Europe, Russia and South America.

The plant-wide DNA automation system improves both operability and safety by turning an excavator cabin or purpose-built cabin into a control room. By providing instant process values, camera images and time trends of all the operable crushing equipment, the system allows a quick overview of the process at any time. To handle varying process conditions such as changing feed material type or moisture, process setpoints can be easily accessed and changed whenever needed. In addition, preset alarms give the alert in unexpected process situations, making process fault detection and troubleshooting faster and less tedious.
