Digitalisation, automation, and data-driven decision-making are rapidly transforming the global milling industry, with SmartMill approach emerging as a key pathway to improved efficiency, consistency, and competitiveness. These trends were highlighted by Swiss technology company Bühler during its presentation at the 90th congress of the National Chamber of Milling (NCM) in mid-March, in Knysna, Western Cape.
Speaking at the event, Fabio Curatolo, Senior Customer Relationship Manager at Bühler Southern Africa, highlighted how the SmartMill concept is helping millers respond to growing operational pressures, tighter margins, and increasing quality and compliance demands.
“Industry platforms such as the NCM congress are extremely valuable because they bring together milling leaders and technology partners to share real-world experiences and align on what the industry needs,” says Curatolo. “These conversations help translate the idea of the SmartMill into practical priorities that millers can implement in their operations.”
In fact, SmartMill is not an end product, but more of a concept made up of hundreds of complementary innovations designed through close collaboration with the industry. According to Curatolo, the SmartMill represents a shift towards more connected, transparent, and automated milling operations. By integrating sensors, digital platforms, and advanced analytics, mills can move from manual checks and experience-based decisions to real-time, data-driven process control.
“The SmartMill means using connected equipment, sensors and software to make milling operations more predictable and responsive,” explains Curatolo. “Operators can rely on real-time data to maintain optimal performance, ensure consistent quality, and react faster to deviations.”
Millers face a complex operating environment
Millers today face a complex operating environment. Volatile raw material quality, rising energy and utility costs, maintenance reliability challenges, and skills shortages are making consistent production performance more difficult to maintain. At the same time, the market is demanding tighter margins, greater traceability, and higher standards of food safety and quality.
“In South Africa, these pressures are even more pronounced because of energy instability and rising operating costs,” notes Curatolo. “SmartMill technologies help millers address these challenges by improving process control, strengthening traceability, and making operations more resilient.”
Digital monitoring and data collection play a central role in this transformation. “Data turns milling from a ‘best effort’ operation into a controlled, evidence-based process,” says Curatolo. “By analysing trends and detecting changes early, mills can adjust parameters proactively, prevent downtime, and maintain consistent output.”
Transition to the SmartMill approach
Bühler supports millers in their transition to SmartMill through a comprehensive approach that spans consulting, engineering, digital solutions, and ongoing operational support. “Our goal is to help millers translate data into measurable improvements in yield, energy use, and plant performance,” says Curatolo. Among the technologies helping enable this transformation are advanced automation systems, digital production management platforms, and specialised process optimisation tools. For example, Bühler’s digital platforms like Bühler Insights and ProPlant allow millers to organise and monitor maintenance, production, and process data in real time.
Solutions such as temperature and vibration monitoring help optimise grinding performance and reduce energy consumption.
One advantage of the SmartMill approach lies in it being an incremental journey rather than a revolutionary moment, allowing customers to join at the point that best suits their business. While the speed and direction of the journey is up to each company, everyone needs to start from the same point.
According to Bühler’s experts, anyone thinking of being part of the journey in the near future should be thinking now about installing sensor technology and the connectivity that offers the necessary production transparency that informs decision making, because this is the foundation of the whole SmartMill process.
Milling sector sees increased digitilisation
Curatolo expects digitalisation in the milling sector to accelerate significantly over the next decade. “We expect stronger automation, wider use of AI-driven analytics for process optimisation, predictive maintenance, and increasing expectations for full traceability across the value chain,” he says. “Sustainability will also be a major driver, pushing mills to reduce energy use, emissions, and waste, while improving resource efficiency.”
However, Curatolo emphasises that a successful SmartMill journey requires more than simply installing new technologies. “The SmartMill works best when it is implemented as a practical, step-by-step programme,” he says. “Clear performance targets, a reliable data foundation, and strong operator engagement are essential. When those elements come together, the result is more efficient, resilient, and competitive milling operations.”
Innovation remains at the core of Bühler’s long-term competitiveness and its ability to create impact for customers. In 2025, R&D expenditure amounted to 4.8% of turnover, with Bühler launching 60 new products successfully into market to reinforce its commitment to purposeful innovation driving performance and sustainability. Bühler’s innovation capability is supported by Bühler’s global innovation network of 26 research and training centres.

And certainly when I reached La Chorerra in 1971 I had a price on my head by the FBI, I was running out of money, I was at the end of my rope. And then “THEY” recruited me and said, “you know, with a mouth like yours there\’s a place for you in our organization“. And I\’ve worked in deep background positions about which the less said the better. And then about 15 years ago they shifted me into Public Relations and I\’ve been there to the present. – Terence McKenna
