Fourdrinier Multi Cylinder High Grade Cultural Paper Machine
Standard Export Packing
Fourdrinier Multi Cylinder High Grade Cultural Paper Machine Technical parameter: 1.Paper kinds: Cultural paper 2.GSM: 30-120g/m2 3. Trim width: 3520mm 4. Working speed: 500m/min 5.Design speed: 600m/min Performance Features: 1.Headbox: The machine adopts full stainless steeel hydraulic headbox.
The ditrbuting bundle is combined with difusion tubes. The difusion tube bundle adopts the difusion-inally section tube through the precise calculation, horizontal distribution and dispersion to the pulp which isfrom the inlet pipe so that the pulp has the uniform distibution eflectc and good dispersion characteristics,which guarantees the quality of paper The cloth paste machine adopts the conical pipe pulp feeding, the pulp inlet cone pipe is combined of bigstraight round pipe, conical pipe and small straight round pipe. The conical pipe has the pressure balanceshow device. The homogenate is a turbulence generator which is combined of fixed hydraulic componentsand made of shaped steel tube whose inlet section is circular and outlet section is square. Between the pressure screen and the head box installed the pulse reduction tank, it can reduce the pulsation from flow systemsignificantly so as to improve the paper index.
2.Fourdrinier forming section: It adopts the cantilever in network case bench, can change the net convenientand shorten the changing net time. It adopts pneumatic constant tension and guarantee the forming wire inthe operation of the tension is constant.
3.Press section: The press section adopts 3 roll/2- -nip combined press. The first nip is the suction reverse press, the second nip is reverse press, the third nip straight press. From the forming section to the secondpressure area is totally enclosed paper injection. It greatly reduces the paper breakage rate. The frame ofpress section adopts the suspension type heat blanket structure, which make it convenient to change felt andshorten the changing net time.
4.Dryer section: The first group of dryer cylinder adopts the single tapestry arrangement, so as to reduce the paper breakage rate. The drying cylinder adopts low noise enclosed gear box drive and circulating oil lubri-cation. Air diverter and far infrared dryer are equipped after the size press, which can ensure paper runningstability and the paper surface quality.
5.Calender: It adopts double-nip soft calendar. According to the request of the paper physical quality, bothnips of it are front soft calendar. The top rolls are nip rolls heated by high temperature oil, while the bottomrolls are nipco rolls with high temperature resistant rubber, which can guarantee front smoothness of paper.
6.Drive section: The complete machine drive section adopts advanced step drive digital transmission frequency control technology, which guarantee the transmission accuracy of each parts and the operation stability ofpaper machine.
