Screening improvements for board and paper making

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

Do you want to have better runnability of the paper machine and improved end-product quality?

We offer customized solutions that will improve the reliability and performance of your screening process. The aim is to ensure the competitiveness of your screening system by reducing screening costs per tonne produced through cost savings (in materials, energy and maintenance) and by improving screening efficiency. Well-screened stock means better runnability of the paper machine and improved end-product quality. Depending on your needs, screening improvement may involve a combination of know-how, services and products from Valmet’s service, improvement and upgrade offerings.

How to keep screening systems efficient?

Our condition management solutions are designed to keep screening 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 screening costs.

Quality improvements are designed to improve pulp quality by using existing screening equipment or to meet pulp cleaning challenges when increasing production. Improved pulp cleanliness will result in energy savings, improved production efficiency, and better runnability of the paper machine.

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

Recoating service that can reduce cost by 30%

Maintenance costs per tonne produced are a key issue in screening. Our recoating service offers one solution for reducing these costs. The same basket can be recoated several times, which reduces costs by some 30% compared to new baskets. Valmet Screen Basket NC provides another solution where only the basket panel is changed and the body of the basket is reused.

Sustainability development is a key issue for Valmet. Our approach consequently also includes a variety of eco-efficient solutions. These extend well beyond energy conservation to the reuse of second-hand machinery, upgrading of existing products, recycling of refiner fillings, recoating of existing screen baskets, etc. in a manner that reduces the need to produce new machinery or new parts. This allows us to use less virgin metals and energy in the manufacturing process than if we were to make completely new machinery and parts each time.
