#45 How can the stock preparation process be improved by real-time monitoring and control?

Stock preparation is perhaps the most important area of the paper and board making process. The way fibers are prepared before reaching the paper machine has a direct impact on product quality, energy consumption, runnability and ultimately mill profitability.

Traditional paper and board mills – up until now – have had to rely on laboratory results to analyze raw material quality to ensure end quality and running efficiency. However, laboratory results often arrive long after the fibers have already passed through refining, making it difficult to correct process deviations in time.

Today, automation and digitalization are changing the reality. Instead of relying on delayed laboratory analysis and operator experience alone, mills can monitor and control fiber properties continuously in real-time and make process adjustments while production is running.

When combined with advanced process controls, PulpEye Fiber Properties Analyzer can reach significant improvements in stock preparation, such as:

Production increase up to 10%
Productivity increase up to 10%
Quality losses reduction up to 11%

In this podcast episode, we speak to Öjvind Sundvall, General Manager of PulpEye at ANDRITZ and explore how real-time fiber analysis with ANDRITZ’s PulpEye Fiber Properties Analyzer is helping mills make smarter decisions, reduce variability, and optimize the entire stock preparation process.
