Working Principle of Headbox

The headbox is attached to the short cycle through the sizing tube and provides the slurry for the forming section. The design and adjustment of the headbox is based on the composition and dynamic characteristics of the slurry, thus affecting the quality of the sheet. Because of the pressure in the headbox paper machine, the pulp can flow. The pressure is produced by the slurry pump. The speed of the slurry pump is controlled by the speed rate of the pulp controlled by the computer.

Function of Headbox

    1. Distribute the paper slurry evenly and stably along the paper machine to ensure the uniform of pressure distribution, flow rate, speed.

    2. The paper machine spare part headbox effectively disperse fiber and prevent fiber agglomeration.

    3. Provide and maintain a steady relationship between the feed flow head and the pulp speed of the incoming paper according to the process requirements.
