Refining improvements for board and paper making

Customized solutions that will improve the reliability and performance of your refining process

Do you want to have better runnability of the paper machine and improved end-product quality? We can help you reduce refining costs per tonne produced through cost savings (in materials, energy, and maintenance) and by improving refining efficiency. Depending on your needs, refining improvement may involve a combination of know-how, services and products from Valmet’s service, improvement and upgrade offerings.Upgrades are typically aimed at increasing refining capacity or efficiency by enhancing the reliability and operational performance of existing refining equipment. We utilize the latest technological advances and components to save energy when performing the upgrades.

How to keep refining equipment in optimal condition?

Our condition management solutions are designed to keep refining equipment in optimal condition. Production and maintenance efficiency are improved through carefully planned and prioritized preventive and corrective maintenance measures. Optimal service intervals will also help to cut refining costs.

Quality improvements are designed to improve pulp quality by using existing refining equipment or to meet pulp quality challenges when increasing production. Improved pulp quality will result in energy savings and improved production efficiency.

Upgrades are typically aimed at increasing refining capacity or efficiency by enhancing the reliability and operational performance of existing refining equipment. Refining upgrades utilize the latest technological advances and components to save energy.

Reduce energy cost by 40% when refining to a give tensile level

One good example of Valmet’s energy saving commitment is our strong development work on various types of refiner fillings, such as MicroBar. It has been proven to save up to 40% energy at a number of mills when refining to a given tensile level. Our turbine housing represents another process improvement that facilitates increased production or extends the lifetime of fillings. This new optimized refiner housing, engineered with the help of computerized flow simulations, enables higher refiner outlet pressures than earlier products.

Cartiere Ermolli: New refiner replaced two old, and saved energy up to 20%

Cartiere Ermolli, produces specialty grades in Italy for flexible packaging like food wrapping papers. When creating specialty papers, doing refining right is fundamental. Mechanical properties of the fiber cannot be destroyed so the amount and the quality of the refining must be right, without any harmful cutting effects. When they needed increase in capacity and end product quality, the solution was OptiFiner Pro refiner.

The world’s biggest OptiFiner Pro refiner saves energy at Savon Sellu

Savon Sellu aims to make their fluting lighter while keeping the same strength properties. They invested in refining rebuild that enables them to pursuit this target while optimizing processes so that they use less energy, control the process better and need less maintenance. They have now two of the world’s biggest OptiFiner Pro refiners to help them in reaching their targets.

24% energy savings with new OptiFiner Pro refiner at Mondi Neusiedler

Mondi Neusiedler Mill in Austria had a clear target in energy consumption reduction. They saw the potential for energy savings and promptly commenced on a project to replace existing short fiber refiners with just one OptiFiner Pro refiner.
