Press roller is the main component of squeezing roller press device is a lot of more phyletic, the old paper machine press section using flat roller, with the improvement of paper machine speed, start using the vacuum press roller, and then developed the grooving squeezing roller, the research and development in the 1970 s the blind hole roller and controllable and high absorbed in the form of vacuum pressure roller grooved roller and the strengths of the blind hole roller, then the other several kinds of new type roller in the 80 s and 90 s and developed the high-speed paper machine with wide pressure area squeezing and bootsUntil now, the development of new press rollers has not been stopped. The purpose of developing new press rollers is to improve the dehydration efficiency, improve the quality of paper and reduce the adverse impact of press on the paper industry.
The press roller is the main component of the press device. There are many types of press rollers, and the press section of old-fashioned paper machines often uses flat press rollers. With the increase of paper machine speed, vacuum press rollers were used, followed by the development of groove press rollers. In the 1970s, blind hole press rollers and controllable medium high rollers were researched and developed. After absorbing the strengths of vacuum pressure rollers, groove rollers, and blind hole rollers, several other new types of pressure rollers subsequently emerged. In the 1980s and 1990s, wide press and shoe press were developed for high-speed paper machines. Researchers have never stopped developing new types of press rollers, with the aim of improving dewatering efficiency, improving paper quality, and reducing the adverse effects of press on paper.
