As the first machine in paper making process, headbox plays a pivotal role in the finished quality of paper sheet.
Generally, headbox contains three main sections: distributor, wire basin and wire plate.
Product Parameters
Adaptive speed : 80-280M/min (designed on requirements)
For example: 1800/200 Open Type Headbox
Paper kinds | Kraft paper, fluting paper |
Raw material | wood pulp, waste paper |
Working speed | 90-180m/min |
Design speed | 200m/min |
Quantitative | 100-190g/m2 |
Spout width | 2100mm |
Pulp inflow consistency | 0.4%-0.8% |
Dryness of finished paper | 93% |
Beating degree | 20-50°SR |
Diameter of breast roll | D400 |
Headbox bottom rail gauge | 2700mm |
Machine type | Left hand machine |
Features
1.The speed of the web pulp can be adjusted by the air pressure above the pulp surface in the compressed air conditioning box (the pulp level remains unchanged, and the appropriate pulp head can be obtained by changing the air cushion head).
2.Using square cone tube and porous plate as the distributor, flat bottomed weir pool has low slurry level and fast flow rate.
How to Choose high quality product?
1 The pulp should be evenly distributed along the width and length of machine. After paper leaves the nozzle through the flow box, the pressure and flow rate should be balanced and consistent, with a stable flow rate and no fluctuations.
2. It can ensure to provide stable web paper speed according to process requirements.
3. Convenient adjustment and flexible control.
4. The flow channel is smooth, free of slurry and easy to clean.
