Paper machine headbox


The headbox equipment is key in the formation of the final product. Its role is to evenly distribute the fibrous mixture onto the forming wire. Thanks to its experience and developments stemming from its applied research, Allimand proposes three categories of headbox for various applications. The Allimand Hydrofiber TM allows the formation of material with a very low concentration.

This characteristic is obtained thanks to advanced filtration technology. Single or multi coats, the Hydrofiber is installed on machines with an inclined wire part and treat long fibres over 25 mm. The final properties of the material can be controlled over a high speed range. Allimand has very high speed Hydrofiber references. The Hydrofiber can produce a wide range of nonwoven and composite products.

Its flexibility, meticulous mechanical design and its high drainage capacity means it can produce unique fibre mats. With the Hydrofiber, Allimand is one of the world leaders in nonwoven and composite production equipment. Compact and designed to prevent fibres from catching, the Allimand air-loaded headboxes are specially adapted for the production of high loaded and very refined papers, technical and speciality papers including coloured paper.

The SFP hadboxes are equipped with a linear header and dilution control whereas the FP headboxes are fed by a manifold.

A pioneer in hydraulic headboxes with basis weight control by dilution, Allimand continues to innovate to provide its customers with the latest technology. The hydraulic headbox S4 combines central header stability, dilution precision and the mechanical rigidity necessary for exceptional results.

An even basis weight, formation quality and orientation stability are obtained even at high speed. Particularly versatile, this headbox is used for a wide range of applications from speciality papers to packaging.

The sheet formation section is the first section of the paper machine which directly influences the physical characteristics, quality and evenness of the sheet formation. Allimand carefully determines the configuration and equipment used for the sheet formation section depending on the types of paper to be produced, the types of fibres and the paper machine production speed.

The other determining element of the formation of fibrous materials is the wire part which is where the dewatering process starts. Allimand designs, manufactures and modifies all types of wire parts, fourdrinier or inclined. The Allimand wire parts incorporate agile cantilever systems to enable quick and safe wire changing and maintenance operations. Contact us to find out more about our fourdriniers.

The Allimand inertial shaking unit can be installed on an existing production line or on a new machine. The Allimand ISA inertial shaking unit has the following characteristics:. Positioned on the wire part, the Top Former is a double wire dewatering unit which mirrors the dewatering process and therefore the formation.

Its main objective is to extract a large quantity of water upwards and therefore limit the length of the wire part. Allimand has many references in these sectors. Contact us to find out more about the Allimand Top Former. The press section follows the formation section on the paper machine. Its objective is to remove as much water as possible from the mat before it is transferred to the dryer part. This is not only a fundamental stage for the sheet characteristics porosity and surface appearance but also economically, reducing steam consumption in the following machine process.

Allimand designs and manufactures different types of conventional presses. Single nip, binip, trinip and tandem, each configuration is adapted to the characteristics of the final fibre product taking into account ergonomics, safety and felt changing times.

Exhaust Hood. Cylinder Mould.Headbox is the key part of the paper making machine, it not only affects the speed of the paper machine, but also affects the quality of the paper.

With the increase of the speed of the paper machine, the time from the ejection of slurry to finalization is reduced to a fraction of a second or even more short. In such a short period of time, if there is no high-quality hydraulic headbox, the paper banners cannot be evenly distributed along the width and width of the paper, and the paper with the good uniformity cannot be made, and the quality paper cannot be produced.

Hydraulic Headbox Benefits:. The pulp flowing out of the hydraulic headbox is uniformly distributed along the paper machine horizontally and the pulp also uniformly distributed along the paper machine longitudinally.

Hydraulic headbox makes the slurry well dispersed in fourdrinier section, so the uniformity of paper can be guaranteed. Hydraulic headbox is suitable for different kinds of pulp and beating degree.

Smooth flow channel. The pulp can smoothly flow to fourdrinier section, which is easy to adjust and control slurry speed. The Headbox provided by Leizhan company has good business, environmental and social benefits. Welcome to contact us if configurar smtp chamilo need any pulping or screening machine.

In order to achieve uniform concentration distribution of paper sheet, a research on the effect of dilution water added to the mainstream on concentration and flow was studied by experimental set-up and mathematical modeling in this paper. Based on the numerical simulation results, a scale model of headbox was derived to predict the water content distribution and pulp consistency distribution. Results show that these models could accurately predict the experimental flow characteristics of a pulp suspension with dilution water added.

Compared with slice regulation, the inverse response problem and its improvement method were discussed. By parameters improvement of pulp consistency model, the reverse response on both sides can be well eliminated or balanced when the dilution water was adopted to cross-directional profile control system.

It ensures that the influence range of a single dilution water valve is controllable, which improves the adjustment accuracy of cross-directional profile control and thus improves the paper quality. In paper making with modern high-speed paper machines, sheet properties must be continuously monitored and controlled to guarantee that the paper product quality specifications are satisfied along both the machine direction MD and cross direction CD.

It is generally recognized that the hydraulic headbox is the most advanced headbox. Modern hydraulic headbox is equipped with dilution water supply equipment for basis weight profile control. The headbox is divided into CD dilution zones spaced 60 mm apart. Dilution water is supplied individually to each dilution zone.

Dilution water volume is regulated by valves connected to electric actuators. These actuators are controlled by the dilution profile control system. The control system is used to locally regulate stock consistency in order to effect basis weight changes. At present, more research is focused on the structure and regulation principle of hydraulic headbox with dilution water. In a more recent study, the shape optimization of headbox is carried out by integration CFD and optimization technology.

The key technology of the hydraulic headbox systems is how to add dilution water, when a dilution water valve operates, what effect it does have on the pulp consistency on both sides, how that really affects, and what expressions are used to depict?

The principle of these problems are not clear. These problems involve complex measurement and control technical problems. In addition, controlling the consistency allows better basis weight profiling profile variations in the machine direction and cross direction than that achieved by slice bending. And analyze the effect of dilution water on slurry consistency of headbox. Furthermore, an accurate modeling strategy can reduce the costs of experiments and prototype equipment when designing headbox.

This work aims to analyze the effect of injecting dilution water on the stock concentration and fiber flow pattern in main pulp stream.Spinnaker partners with Paper Machine Services Inc.
