The development of paper machine and pulp equipment in recent yearsInternationally, modern papermaking machinery and papermaking pulp equipment are developing rapidly, and the degree of automation is getting higher and higher. At present, a single chemical pulp production line has a production scale of 600,000 t/year

The sandwich paper machine solves the problems caused by the increasing speed of modern Fourdrinier paper machines, especially the difference in paper product characteristics on both sides of the Fourdrinier paper machine, poor micro uniformity

Many design parameters are used when designing a paper machine. These design parameters are mainly determined by the following basic data.1. Basic data expressing the production capacity and adaptability of the paper machine

The paper machine should run within the speed range of the highest output:Assuming that a well-designed paper machine has a good market for the product, the main factors affecting productivity and profitability are: papermaking rate, paper machine speed, and yield.

The working environment of the paper machine is humid and high temperature, and some equipment is also accompanied by impact loads. Therefore, the choice of lubricant mainly considers its emulsification, water resistance, heat-resistant oxidation stability and load resistance.

The paper machine is a complete set of pulp forming equipment that integrates the headbox, the wire section, the press section, the dryer section, the calender, the reeling machine, and the main engine of the transmission section, as well as auxiliary systems such as steam, water, vacuum
