Paper Machinery Hydraulic Headbox for Paper Mill
 

Product Description

Paper machine headbox
The paper machine headbox is an equipment that supply very low consistency stock into the forming section uniformly. The formation and uniformity of the final paper product depends on the dispersion of the fiber and fillers. The furnish delivery system varies on the construction of the headbox. It has a significant effect on paper qualities. All the headbox are not suitable for all grade of paper and machine speed. A well constructed Headbox can provide high quality board and paper and higher productivity. So the design should be properly. Now a days Hydraulic type headboxes are commonly used in the pulp and paper industry. The headbox is also known as flowbox.
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 pad headbox , the discharge velocity from the slice depends directly on the feeding pump. For this reason they commonly known as pressurized headbox. The hydraulic headbox has no air pad, it is fully enclosed.

In case of air pad 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 system.

Function

The headbox has many functions among them the following three functions are very important.

  1. It spread the stock uniformly along the width of the forming fabrics.
  2. It provides the stock at constant velocity according to the paper machine speed.
  3. Create control turbulence and uniform suspension to eliminate fiber gathering.

If the headbox does not perform these functions correctly then the quality of the paper will be greatly hampered.
 

Our Advantages

You will get many benefits from the well constructed headbox. It can improve formation and paper quality, reduce number of breaks and downtime, fewer pinholes, dirt spots, improve runnability, increase 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.
