What is the difference between a paper machine and a long screen

The paper made is not the same roughness.

Joint equipment for paper forging. It is mainly composed of netting, pressing and drying. There are two types of nets: round mesh and long net.

The press section is composed of press rollers and papermaking wool cloth. The dryer section consists of one or several dryers. Some long web machines are also equipped with mechanical calenders to improve the smoothness and tightness of the paper, among other things.

There are many types of paper machines, such as single-dryer paper machines (also known as Yankee paper machines) that manufacture single-sided glossy paper, long-net multi-dryer paper machines that manufacture general paper, tissue paper machines that manufacture typewriting paper and cigarette paper, and cardboard machines that manufacture cardboard.

It generally refers to the machines that make all kinds of paper and cardboard, including dry paper machines and wet paper machines, and generally refers to wet paper machines. According to the structure of the forming part, there are three types: long net paper machine, rotary screen paper machine and clamp screen paper machine. Their technical characteristics are often expressed in the form of their production capacity, paper grade, specification, vehicle speed and dryer section.

Such as long net multi-cylinder paper machine, rotary screen double-cylinder paper machine, newsprint paper machine, cultural paper paper machine, cardboard paper machine, etc. The paper machine is a complex and large interconnected machine, including flowing, forming, pressing, drying, vacuum, white water and fiber**, water and steam supply, hot air and heat**, compressed air, lubrication and transmission systems. Some paper machines are also equipped with embossing, wrinkling, sizing, coating, calendering, slitting and other mechanisms.

Due to the different types of paper made, the configuration of various paper machines is not exactly the same.

A machine used to make paper in the paper industry. It is mainly composed of headbox, net section, pressing section, drying section, calendering section, and paper rolling section. There are many types, such as rotary screen paper machines, long screen paper machines, single-dryer paper machines that manufacture single-sided glossy paper, and sandwich paper machines with two webs.

1. The main difference between rotary screen and long screen paper machine The rotary screen paper machine pulp is formed on a cylindrical net cage, which is generally immersed in the slurry, and the long screen paper machine is generally the slurry sprayed on an unprovoked polyester net forming, and there will generally be a very long horizontal net case.

2. The paper machine with multiple rotary screen cages used for copying cardboard is generally called multi-rotary screen paper machine, but some factories are also called stacked screens, and the general stacked screen paper machine is composed of several long nets or long nets and rotary screens formed and then compounded together.

3. I am not familiar with it, and I personally think that the bobbin paper is better.

4. I didn't understand it.

Rotary screen paper machine (cylinder machine; VAT machine), a paper machine with a rotary screen as the former. According to the different number of formers and drying dryers, various types of paper machines are formed, such as single-screen single-cylinder paper machine, double-screen double-cylinder paper machine, multi-network and multi-cylinder cardboard machine, etc.

Long net paper machine, the most widely used paper machine. The main feature of the long net paper machine, also known as the long screen paper machine, is that it has a conveyor-type forming section composed of an endless mesh.

The new movable curved plate former (with pressure feeding) rotary screen paper machine is suitable for the production of corrugated base paper, liner cardboard, toilet paper and low- and medium-grade graphic paper. It can produce 90 130g m2 of different low-weight papers, and its speed can reach 220-250m min, which can increase the output of the old movable curved board network groove paper machine by nearly 2 times.
