Paper Mill Headbox for Paper Machine
The headbox is a key part of modern paper machines. 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.

Paper machine headbox is the key of paper machine, it has three functions:
1. Spread the stock evenly along the width of the paper machine.
2.Accelerate the stock up to the machine operating speed.
3.Suspend the pulp fibers throughout the outgoing slurry.
Working principle
The step diffusion pulp inlet is made of stainless steel 304. organic glass 3 level steps spring back pulp spread. Box is welded stainless steel. 2 stainless steel evener roll. Top and bottom lip are made of stainless steel 316L. Top lip can be adjusted totally or partly. Spinner distance is 120mm. Headbox can be adjusted horizontally and lip can be adjusted up and down and has Micro adjustment function. The control system of headbox can connect with DCS system signal to achieve program logic control. Proper scope of starching amount is 1:2. There is organic glass prothole on the box to observe the pulp level.
