High Quality Hydraulic Headbox for Paper Forming Section in Paper Mill
The headbox is a key part of a modern paper machine. Its structure and properties play a decisive role in the formation of paper sheets and the quality of paper.
Hydraulic Headbox Function:
1. Can effectively disperse fibers. The high-turbulence headbox can
generate high-intensity micro-turbulence, which can effectively
disperse fibers, prevent fiber sedimentation and re-flocculation,
and effectively improve the strength of paper sheets.
2. Distribute the stock evenly across the paper machine.
(Determines the lateral quantitative distribution of the paper web)
3. The spraying is stable to ensure that the speed of the slurry is
coordinated with the speed of the net. (Determines the longitudinal
quantitative distribution of the paper web)
Headbox Types:
Normally the headbox is categorized into three types such as open
type, air pad type, and hydraulic type.
Among them, the hydraulic headbox is designed for a high-speed
modern paper machine (above 300 m/min) whereas open headbox is used
in low-speed paper machine. In hydraulic and air cushion headbbox ,
the discharge velocity from the slice depends directly on the
feeding pump. For this reason, they are commonly known as a
pressurized headbox. The hydraulic headbox has no air pad, it is
fully enclosed.
In case of an air cushion headbox a pond level is maintained. Above
the level it contains pressurized air. The stock level is known as
head, which is controlled by air pressure. The head determines the
slice jet speed. It contains two or three Rectifier roll.
Moreover multi-layer hydraulic headbox is available which is
designed for making tissue paper and lightweight containerboard.
Each layer has different furnish compositions and delivery systems.
Our Advantages
You will get many benefits from the well-constructed headbox. It
can improve the formation and paper quality, reduce the number of
breaks and downtime, fewer pinholes, and dirt spots, improve
runnability, increase the machine speed, stabilized paper caliper,
improve water removal, and reduce chemical cost. All these
properties are achievable, if the CD basis weight profile, main
fiber direction, uniform formation, flatness, etc. are perfect.
