IGO greatly improves grinding mill efficiency through predictive control using 3DPM size distribution meaurement
IGO Limited, the owner and operator of the Nova Nickel Operation in Western Australia has trialed and purchased 3DPM system for on-line particle size distribution (PSD) measurement on conveyor belts using 3D imaging. IGO uses the size distribution as a “disturbance variable” in a model predictive controller for a SAG mill. The model can predict by up to 100 seconds in advance the effect on the SAG mill weight. This has greatly improved the stability of the grinding circuit as well as increased the energy efficiency of the Mill.

International Mining Magazine takes a look at 3DPM
Full Article 2020-06-04: Visualising the future of particle measurements with 3DPM
"The 3DPM vision system has had quite a journey. Since the first prototype was installed at LKAB’s Malmberget iron ore to help the miner optimise its pellet production, the system has helped ‘settle the argument’ between mine and mill at base metal mines in Europe and improve the quality of coke being fed to blast furnaces in Japan.
The future looks bright too, with the potential for the system to play a major role in the automation of mine process plants."
Rio Tinto orders 3DPM
In conjunction with our product partner MBV-Systems, Innovative Machine Vision is proud to annouce that Rio Tinto, one of the worlds largest mining companies, has selected to trial 3DPM®at a mine site in Western Australia. The purpose of the trial is to evaluate the use of 3DPM to increase knowledge and understanding of material flow and hence improve production efficiency and product quality in the mine.
3DPM® provides online particle size distribution (PSD) measurements of rock and bulk material on conveyor belt using 3D imaging and advanced algorithms.
"Its been a real pleasure working with Rio Tinto to scope out and understand the potential, or lack of potential with different PSD measurement options. As a result, it's very satisfying that they have selected 3DPM for a trial" says IMV Principal Scientist Matthew Thurley.
"This is a very important order for us since Rio Tinto is a world class mining company with operations all over the world", says Lars Lindqvist CEO at MBV Systems.
World-class metals company installs another 3DPM particle size distribution measurement system
European mining and metals company Boliden has decided to install another 3DPM system in their mine in Garpenberg. The first system we delivered four years ago when Boliden was searching for a system which could help them to improve their process knowledge and control strategies for crushers and grinding mills at Aitik. Three years ago they wanted to push the limit even further at their Garpenberg facility to be able to detect boulders and rock bolts on-line in a safe way. These were new features in 3DPM but MBV Systems guaranteed the functionality. Today, the system is in continuous operation at Boliden Garpenberg, and an additional system is commissioned at Boliden Aitik. With this new order, Boliden Garpenberg will have two systems in operation in their mine. Using 3DPM Boliden can take control of particle size, volume flow and safely detect unexpected boulders or rock-bolts after their crushers.
Within mining and metal industry, crushers and grinding processes are big energy consumers, improved handling within these areas are therefore necessary for a long term sustainable production.
Boliden is very satisfied with the results. Andreas Forslund project leader at Boliden Garpenberg says: "MBV Systems has delivered equipment that provides us with reliable boulder and rock bolt detection in a demanding environment. The equipment has given us the opportunity to take control of where we handle boulders and rock bolts in our feeding line. This also means that the stops generated can be handled in a safer and easier way. "
Nippon Steel installs 3DPM
Nippon Steel (one of the worlds largest steel companies) has decided to install 3DPM particle size distribution measurement system in Japan in order to give better knowledge and understanding of the material and hence improve blast furnace efficiency and product quality.
Japanese steel producer JFE Steel optimizes blast furnace production using Swedish 3D machine vision technology
One of the world's most advanced steel producers, JFE Steel in Japan, has improved feed-control for optimizing the coke particle size distribution to the blast furnace at their west Japan steelworks. After extensive onsite testing, JFE Steel has bought multiple 3DPM® online particle size distribution measurement systems enabling feed-control and improving blast furnace production.

Why Commercial In-Pit Rock Fragmentation Systems cannot be Reliable
Principal Scientist Dr Matthew Thurley writes about in-pit fragmentation measurement systems available on the market and how they cannot be reliable due to using photographic based imaging in an environment with uncontrolled lighting and conditions unsuited to this measurement method.
