The vacuum box and suction box in a Paper Machine are both important components for the paper - making process.
Vacuum Box
Function: The vacuum box is mainly used to remove the water from the wet paper web. It creates a vacuum environment to suck out the moisture, which helps to increase the dryness of the paper and improve its strength. This is crucial for the subsequent processing of the paper.
Customization: It can be customized in terms of size and shape to fit different paper machine widths and production speeds. The vacuum level can also be adjusted according to the specific requirements of different paper grades, enabling precise control over the water - removal process.
Suction Box
Function: The suction box is used to assist in the dehydration of the paper web. It works by applying suction force to draw out water, especially in the initial stages of paper formation. This helps to form a more uniform paper structure and reduce the water content to an appropriate level for further processing.
Customization: It is highly customizable with options for different suction intensities and surface textures. The number and arrangement of suction nozzles can be customized based on the paper - making process and the type of paper being produced. This allows for optimized dehydration efficiency and better paper quality.
