Product Description

Product Description

Air Cushion type headbox can increase the sizing pressure to meet the requirements of medium and high speed paper machines. The headbox consists of square taper tube device, evener roll device, top lip plate adjusting device, box body,control system, spraying device, air path system, etc.The headbox is designed with customer performance parameters, which can ensure work performance.

Advantage

1.It can be used to produce the paper sheet with uniform and stable quantity, and there is no longitudinal flow on the web;
2.The lip area of headbox should not be affected by pressure, temperature and opening degree of the lip to ensure the uniform distribution of the width;
3.Easy to keep the box clean;
4.The ratio of jet to wire speed is controllable.

Application

1.Headbox is used for sizing in fourdrinier wire section of paper making machine for producing cardboard paper, corrugated base paper, writing and printing paper, offset paper and so on.
2.Applicable speed range: 160-480m/min

How to choose

Requirements for good headbox
1. The paper material can be evenly distributed along the banner and longitudinal direction of the paper machine. It is required that the pressure, flow and flow rate of the paper material sprayed onto the net after leaving the nozzle after passing through the headbox shall be balanced and consistent, the flow shall be stable without fluctuation, the full width shall be uniform and consistent, and there shall be no cross flow and large eddy current.

2. It can effectively disperse fibers and prevent flocculation. It is required that the web paper material must be a uniformly dispersed fiber suspension, with uniform concentration distribution, and can maintain the non directional arrangement of fibers in the paper material flow.
3. It can ensure to provide stable web paper speed according to process requirements.
4. Convenient adjustment and flexible control.
5. The flow channel is smooth, free of slurry and easy to clean.
