4600 Low Basis Weight High Strength Corrugated Base Paper Machine for Paper Making, Paper Mill Machinery
The width of clean paper is 4600mm, which is mainly used to make low-quantity high-strength corrugated base paper. The paper machine is mainly divided into the following parts: headbox, fourdrinier wire section, press section, front drying section, inclined surface sizing machine, rear drying section and coiling section.
1. Headbox: Air-cushion headbox, by controlling the gas pressure in the headbox, it can control and stabilize the sizing head of the online slurry.
2 . Wire Department: Single Fourdrinier wire, main components: breast roll, forming plate, dewatering plate, vacuum box, vacuum couch roll, net driving roll, net guide roll and frame, etc.
3. Pressing section: divided into one pressing, two pressing and three pressing. The first press is a K-type compound press with a vacuum suction roll. The K-type compound press is equipped with a rubber-coated metal roll, a vacuum press roll, a stone roll, and is equipped with upper and lower felts; The second and third presses are large rolls Diameter press, each equipped with two rubber-coated metal rolls, and equipped with upper and lower felts. The first press, the second press and the third press are equipped with felt guide rollers and felt suction boxes. The first press, the second press and the third press are pressurized by corrugated pneumatic tires.
