Preparation before using the headboxThe headbox has always been considered the heart of a paper machine and plays a decisive role in the quality of the paper. The headbox of a modern paper machine is very automated, but it is still necessary to know how it operates. This article mainly introduces th
The air cushion headbox control system mainly controls the pressure and liquid level inside the headbox. By adjusting the rotational speed of the flushing pump and the Roots blower, the sizing amount of the flushing pump and the amount of air blown by the Roots blower will be changed.
The dilution method can be roughly divided into mixed box type (mostly used for rotary wire paper machines and low-speed narrow-width Fourdrinier paper machines) and punching tank type.
There are many factors affecting the quality of paper web forming, which are complementary to the beating situation, the slurry conveying method, the structure of the headbox and the configuration of the wire section.
The earliest used headbox was the open ram headbox, which was produced before the Fourdrinier brothers invented the Fourdrinier paper machine in 1804.
The headbox is a key component of a modern paper machine and the key hub connecting the two parts "conveying" and "forming".
