Our modern infrastructure is built on rocks, metals, and minerals. These raw materials are very often produced by crushing. The crushing industry has a considerable environmental footprint. Just like others, it has to find new ways and practices to contribute to limiting the global warming to 1.5 ºC.
In his dissertation, MSc (Tech) Pekka Itävuo developed techniques that make it possible to measure the performance of crushing circuits online. He also introduced methods that ensure consistent and efficient long-term production.
The developed methods represent a major leap forward in the area of process control of crushing circuits. In practice, this can mean up to 10-40 % gains in the performance. That means more production, less waste, lower energy consumption, smaller environmental footprint, and of course higher profit.
“Developed methods can be expected to have a significant impact on how efficiently crushing plants will be operated in the future. It’s a win-win situation for the industry and the environment,” says Pekka Itävuo.
Pekka Itävuo is from Tampere, Finland and he currently works as a Manager, Digital Development at Metso Outotec.
Public defence on Friday 5 May 2023
The doctoral dissertation of M.Sc. (Tech) Pekka Itävuo in the field of Automation Science and Engineering titled Process Control of Crushing Circuits will be publicly examined in the Faculty of Engineering and Natural Sciences at Tampere University on Friday 5 May 2023 at 13 o’clock at Hervanta campus in the auditorium K1702 of the Konetalo building (Korkeakoulunkatu 6, Tampere).
