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.
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.
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, 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.
Valmet delivered world’s biggest OptiFiner Pro refiner to save energy at PowerFlute's Savon Sellu mill in Finland. After refining rebuild, the paper mill uses 30% less energy while achieving the same freeness values as before. Besides energy savings, the refining process is now controlled much more accurately.
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.
