The Corrugated / Kraft paper machine is the general name of the whole set of equipment which makes the pulp form the web, including the headbox, the forming section, the press section, the dryer section, the calender, the winder, the transmission part and the auxiliary systems such as steam, water, vacuum, lubrication and heat recovery.

The Corrugated / Kraft paper machine is the general name of the whole set of equipment which makes the pulp form the web, including the headbox, the forming section, the press section, the dryer section, the calender, the winder, the transmission part and the auxiliary systems such as steam, water, vacuum, lubrication and heat recovery.

Our corrugated paper machine can be designed with cylinder mould type or fourdrinier wire type based on the speed(capacity)and quality requirements,the paper width up to 5200mm,speed up to 600m/min,capacity up to 500 t/d.The raw material could be recycled paper or virgin pulp, the basic weight from 80-180gsm.

Forming Section

The forming section is composed of headbox, chest roll, forming fabric, vacuum suction box and couch roll. The headbox distributor sprays the slurry from the conveying system evenly to the forming fabric, and the slurry speed should match the wire speed.

Press section

The formed wet paper is further dehydrated by means of pressure. It consists of two hard and soft rollers, such as stone roller and rubber roller. The press section is composed of pressing groups of the same or different forms, in which the vacuum suction device is also included in the habit. When pressing, the appropriate specification of press felt is used to support the paper sheet, which can evenly distribute the pressure and take away part of the water from the press, and can enhance the pressure and improve the dehydration ability of the press.

Dryer Section

A group of dryers is driven by gears or dryer screen, and a dryer section is composed of several groups of dryers. The linear speed of each group of dryer can be adjusted separately to maintain the micro speed difference between each group of dryer to compensate the shrinkage of paper in the drying process. The dryness of the paper out of the drying section is generally about 92-94%.

Surface Finishing Section

In the paper machine after the mechanical calender calendering, so that the paper surface is flat and consistent. The mechanical calender is made of a number of cold cast iron rollers. The paper surface is flattened by the weight of each roller or by additional pressure.

Transmission system

All parts of the paper machine are connected and run synchronously to form a mechanical and electrical integration. It is composed of mechanical decelerating device, speed regulating and stabilizing device, partial transmission device, etc., all of which use electric power as the power source.

White water system

The paper machine forming section dehydration recovery, treatment and reuse system. Including white water collection, transportation, filtration or sedimentation, air flotation and other equipment, to separate and recycle fiber and filler reuse, as well as the clean white water recycling system in the papermaking process.

Auxiliary system

It is composed of electrical system, vacuum system, lubrication system, workshop steam supply and exhaust system, paper loss treatment system, compressed air system, steam supply and water supply and drainage system.
