Product Description
Headbox plays a decisive role in paper making process, it in charge of put the pulp suspension on the wire at a constant speed and with a defined fiber direction. It considerably influences the paper's technological performance. Therefore, there are high requirement on it's accuracy and precision.
Classification
Open Type Headbox
lt's suitable for the paper machine with working speed 80-280m/min as the requested design.
Hudraulic Headbox
Used for sizing in fourdrinier wire section of paper making machine for producing the cardboard paper, corrugated base paper, writing and printing paper, offset paper and so on.
Air Cushion Headbox
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.
Applicable speed range: 160-480m/min
Advantage
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.
Feature
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.
Packing and Shipping
1. International package (Wooden case, carbon cast and pallet);
2. Container (as customer requirements)
3. It is suitable for long distance ocean transportation and some small parts can be transported by air.
