Detailed introduction

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)There are two types of headbox, 3800 and 4200.
Head Box such as open type Head Box, air-cushioned Head Box, hydraulic Head Box, which is widely demanded by our customers. The Head box serves three important functions in the paper production process. If the Head box does not perform acceptably in any of these three functions, the quality of the paper produced will be greatly diminished.
Headbox provides uniform lapping on a flat net weight of the paper machine.
Headbox used in the manufacture of a wide range of papers with different densities.
