Air-Cushion / Open / Hydraulic Type Headbox for Paper Production Making Machine Headbox for paper making mill machine ,as an important paper machine part, is the first part from pulp making to paper production. Its structure and properties are decisive for the formation of the paper and the quality of the paper. Can effectively disperse fibers. The high turbulence headbox produces high-intensity micro-motion, which effectively disperses the fibers, prevents fiber precipitation and re-flocculation, and effectively increases the strength of the sheet. Distribute the paper stock evenly along the paper machine. (Determining the horizontal quantitative distribution of the web) The shotcrete is stable, ensuring that the pulp speed is coordinated with the web speed. (Determining the longitudinal quantitative distribution of the web).
