In the world, modern papermaking machinery and equipment 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 reaches 600,000 tons / year production scale, the production capacity of a single paper machine reaches 400,000 tons / year, the speed of 2800m / min, 10m wide high-speed wide paper machine has been applied in production.

At present, the papermaking machinery and papermaking equipment needed by large papermaking enterprises in China, Most are dependent on the import of a single product, Production equipment of 420 tons of waste paper pulp and 250 tons of deink pulp per day, Daily output of 300 tons and daily output of 450 tons of chemical wood pulp production equipment, daily continuous boiler of 120 tons, RDH intermittent boiler of 150 tons, annual output of 70000 tons of C tons MP pulp production equipment, annual output of 65000 tons of APMP pulp production equipment, annual output of 60000 tons of CMP pulp production equipment and annual output of 100000 tons of thick pulp oxygen bleaching and chlorine dioxide bleaching equipment, Domestic products have been introduced.

Paper pulp equipment

In terms of paper machine, the introduced domestic press has reached 5590mm, speed 1800m / min and width 8600mm, 1000m / min, production capacity of nearly 200000 tons / year; the production capacity of the introduced toilet paper reached 100 tons / d, speed of 2200m / min, speed width 2700mm; the introduced output of coated white paper has reached 350000 tons / year. At the same time, it introduced the corresponding pulp conveying equipment and washing and concentration equipment, and introduced the distribution control system (DS) and quality control system (QCS).

Paper machinery and equipment

At the same time, due to the progress of science and technology, the domestic papermaking machinery and paper pulp equipment manufacturing also mastered the number of large paper pulp equipment core key technology, such as: for the wood pulp production transverse tube type continuous boiler, waste pulp complete sets of production equipment, high concentration pulp oxygen bleaching and hydrogen peroxide bleaching key equipment, alkali recovery system key equipment, new environmental protection equipment and adopt a variety of new technology combination of all kinds of paper machine, coating machine and so on.

As you can see, papermaking enterprises in China, especially large papermaking enterprises, the degree of modernization and automation is higher and higher, and the application of pulp and paper process of machinery and equipment has new and advanced, clearly reflects the advantages of high speed, high quality, high efficiency and environmentally friendly, and 20 years ago China papermaking machinery and paper pulp equipment condition, can not be compared.
