Delivering high-quality products, while keeping production costs low and plant efficiency high, is an ongoing challenge for all process industries. Traditional industries such as cement, face numerous challenges to reduce the cost of operations while maximising the yield and improving quality at the same time. With the global pandemic leading to unprecedented changes around the world, it could not have been more disruptive for the cement industry to embrace digital technologies and harness big data to improve productivity, availability, and quality across the value chain at this time, but for many operators, the results are already showing.

Advanced process control and analytics
Cement is an energy-intensive industry in which the grinding circuits use more electrical energy and account for most of the manufacturing cost. Advanced process control (APC) and related optimisation strategies can help cement manufacturers to reap the real efficiency benefits of digital technology, without sacrificing stability or quality, even as business changes and grows.

Digital APC solutions control, stabilize and optimise various cement processes, helping plant managers achieve profitability and drive towards sustainability targets. These solutions enable manufacturers to optimise coal, raw material, and finished cement grinding by increasing throughput and securing consistent output quality while lowering energy consumption. Digital advanced data analytics offer tremendous opportunities to increase efficiency and further optimise production processes. Now with the emergence of new digital technologies, machine learning models can provide productivity improvements in addition to APC solutions.

Making way for Artificial Intelligence
When planning and implementing a digital strategy, it is important to take a holistic approach. This means moving the process from typically siloed and discrete functions to one in which all processes are connected, via developments in the Internet of Things (IoT) technologies, and then automated. It is then possible to move towards autonomous operations-optimisation and asset management functions happening largely without human intervention, and within a secure environment. The key to successful digitalization is data, collected directly from connected equipment and processes or derived from soft sensor models.

APC and analytics provide the ability to make predictions and estimations about process performance, even in the absence of reliable measurement data, for example, when real-world measurement would be too expensive or to increase the frequency of data input and provide backup for unreliable measurements.

In such cases, analytic models can be deduced from either first principles or process data. Analytic models include graphical (first principles), linear regression, non-linear regression, principal component analysis, artificial neural networks, and support vector machines. Users can test various models and choose the one with either the best fit or performance statistic, thereby leveraging state-of-the-art advanced analytics.

Use of Artificial Intelligence in Blaine prediction
The quality of cement is determined by the Blaine number. The Blaine of cement refers to the measure of the specific surface area or the fineness of the cement. Since process adjustments are made based on this quality measurement, infrequent sampling may result in production loss and inconsistent product quality.

Predictive Quality Analytics makes it possible to accurately forecast cement quality in real-time at any point in the production process, thereby reducing the overspending that is typical in efforts to meet quality targets.

Blaine is measured in a laboratory at a frequency of every one to two hours and is used in the control system to maintain consistent quality and high levels of production. Although the data can be utilised for process control, it does not provide real time insight into the process. This manual approach has limitations and ideally requires a predictive modeling technology that can predict Blaine every few minutes to maintain consistent quality, improve operational stability and reduce variability.

Evolution of the soft sensor
To drive the need to apply predictive quality analytics to Blaine, a soft sensor is developed using data-driven machine learning algorithms to predict Blaine at desired intervals using relevant production parameters such as fresh feed, separator speed, grinding pressure, mill DP, etc.

This can be accomplished by following the steps:

Collect historical data from the control system for model training (production parameters and lab data)
Data cleansing (e.g. removal of data during mill stoppages, etc.)
Create a fullyautomatic regression training model selecting the best fit from the library of models
Deploy the model and test the model accuracy using the real-time online data
Automatic data pull and retraining of the model if the accuracy is not met
Predicted Blaine output is used for further control

As a result, a prediction model transforms cement quality ??Blaine from an output process parameter to an input parameter which helps in sustaining the benefits via adaptive re-modeling and tuning. The efficiency of the process can be improved considerably through this approach since Blaine lacks continuous measurement in real-time and can be prone to infrequent sampling. Hence, operators can make more informed decisions using the information available.

Recent developments in advanced analytics have made machine learning models more easily accessible to users. But the true power of a machine learning algorithm can be harnessed only when domain knowledge is applied along with these algorithms. Data cleansing, anomaly removal, analysing the correlation of parameters, result interpretation can be carried out efficiently with expertise in domain knowledge.

Having served the cement industry for more than a century, building up knowledge and know-how of electrification and process control, ABB specialises in increasing plant performance and improving energy efficiency. Using ABB?? proven analytical and process modelling tools, along with our in-depth industry specific knowledge, we can provide a clear path for plants to achieve operational excellence.

Dyanesh Wanjale, Managing Director, Gebr. Pfeiffer discusses the need to innovate grinding technologies to make the manufacturing process more efficient and less fuel consuming.

Gebr. Pfeiffer stands at the forefront of grinding technology, delivering energy-efficient and customised solutions for cement manufacturers worldwide. From pioneering vertical roller mills to integrating AI-driven optimisation, the company is committed to enhancing efficiency and sustainability. In this interview, we explore how their cutting-edge technology is shaping the future of cement production.

Can you tell us about the grinding technology your company offers and its role in the cement industry?
We are pioneers in grinding technology, with our company being based in Germany and having a rich history of over 160 years, a milestone we will celebrate in 2024. We are widely recognised as one of the most efficient grinding technology suppliers globally. Our MBR mills are designed with energy efficiency at their core, and for the past five years, we have been focused on continuous improvements in power consumption and reducing the CO2 footprint. Innovation is an ongoing process for us, as we strive to enhance efficiency while supporting the cement industry’s sustainability goals. Our technology plays a critical role in helping manufacturers reduce their environmental impact while improving productivity.

The use of alternative fuels and raw materials (AFR) is an ever-evolving area in cement production. How does your technology adapt to these changes?
Our vertical roller mills are specifically designed to adapt to the use of alternative fuels and raw materials. These mills are energy-efficient, which is a key advantage when working with AFR since alternative fuels often generate less energy. By consuming less power, our technology helps bridge this gap effectively. Our solutions ensure that the use of AFR does not compromise the operational efficiency or productivity of cement plants. This adaptability positions our technology as a vital asset in the industry’s journey toward sustainability.

What are some of the challenges your company faces, both in the Indian and global cement industries?
One of the major challenges we face is the demand for expedited deliveries. While customers often take time to decide on placing orders, once the decision is made, they expect quick deliveries. However, our industry deals with heavy and highly customised machinery that cannot be produced off the shelf. Each piece of equipment is made-to-order based on the client’s unique requirements, which inherently requires time for manufacturing.
Another significant challenge comes from competition with Chinese suppliers. While the Indian cement industry traditionally favoured our technology over Chinese alternatives, a few customers have started exploring Chinese vertical roller mills. This is concerning because our German technology offers unmatched quality and longevity. For example, our mills are designed to last over 30 years, providing a long-term solution for customers. In contrast, Chinese equipment often does not offer the same durability or reliability. Despite the cost pressures, we firmly believe that our technology provides superior value in the long run.

You mentioned that your machinery is made-to-order. Can you elaborate on how you customise equipment to meet the specific requirements of different cement plants?
Absolutely. Every piece of machinery we produce is tailored to the specific needs of the customer. While we have standard mill sizes to cater to different capacity requirements, the components and configurations are customised based on the client’s operational parameters and budget. This process ensures that our solutions deliver optimal performance and cost efficiency. Since these are heavy and expensive items, maintaining an inventory of pre-made equipment is neither practical nor economical. By adopting a made-to-order approach, we ensure that our customers receive machinery that precisely meets their needs.

The cement industry is focusing not only on increasing production but also on decarbonising operations. How does your company contribute to this dual objective, and how do you see this evolving in the future?
Decarbonisation is a key focus for our research and development efforts. We are continuously working on innovative solutions to reduce CO2 emissions and improve overall sustainability. For example, we have significantly reduced water consumption in our processes, which was previously used extensively for stabilisation. Additionally, we are leveraging artificial intelligence to optimise mill operations. AI enables us to monitor the process in real-time, analyse feedback, and make adjustments to achieve optimal results within the given parameters.
Our commitment to innovation ensures that we are not only helping the industry decarbonise but also making operations more efficient. As the cement industry moves toward stricter sustainability goals, we are confident that our technology will play a pivotal role in achieving them.

Can you provide more details about the use of digitalisation and artificial intelligence in your processes? How does this improve your operations and benefit your customers?
Digitalisation and AI are integral to our operations, enabling us to offer advanced monitoring and optimisation solutions. We have developed three distinct models that allow customers to monitor mill performance through their computer systems. Additionally, our technology enables real-time feedback from our German headquarters to the customer. This feedback highlights any inefficiencies, such as when a parameter is outside the optimal range,
and provides actionable recommendations to address them.
By continuously monitoring every parameter in real time, our AI-driven systems ensure that mills operate at peak efficiency. This not only enhances production but also minimises downtime. I am proud to say that our mills have the lowest shutdown rates compared to other manufacturers. This reliability, combined with the insights provided by our digital solutions, ensures that customers achieve consistent and efficient operations. It’s a game-changer for reducing costs and enhancing overall productivity.
