Stock preparation

Stock preparation and approach flow system design impacts both the cost and quality of final products produced on the paper machine. Final sheet properties and web runnability are vitally dependent on the stability of the blended furnish, the fiber quality developed in refining, and the mixing of fillers and chemicals. Valmet has the complete range of equipment and services from single-application processes to complete stock preparation and paper machine approach systems.

Our broad range of technologies in pulping, refining, screening and mixing can be tailored to specific raw material, end product grade requirements and mill conditions. Paper, board and tissue machines can all benefit from better runnability and improved product quality with minimal production costs.
