Description

Paper making press felt refers to the fabric felt used for paper forming and conveying in the paper making industry. It is used for paper forming, wet paper dewatering and conveying. The processing method is to first make a coarse mesh and thin base cloth with synthetic fibers, and then spread them with chemical fibers. After needle punching, chemical treatment, resin finishing and heat setting, it is required to have good dehydration, smoothness, and dirt resistance. Resistance, abrasion resistance, dimensional stability, chemical resistance, antibacterial resistance, heat resistance and hydrolysis resistance, etc.

Pressure Screen

The pressure screen adopts the upward flow structure design of the bottom feed slurry, the bottom discharge heavy slag, and the top discharge light slag. The light impurities and the air in the slurry naturally rise to the top slag discharge, and the heavy impurities can settle into the bottom as soon as they enter the body.it Include Screen basket,Rotor,housing and transmission.

Gravity Thickener

Disc thickener is mainly used for washing and thickening pulp in pulping and paper making process.

High Density Cleaner

High consistency centricleaner for paper pulp machine mainly applied to remove all kinds of heavy impurities in paper pulp,like staples,stone,glasses,etc.

Hydrapulper

The hydrapulper is used mainly for breaking out all kinds of pulp board, and broke all kinds of paper.

Thruster / propeller

Thruster is suitable for pulping process of pulping and papermaking enterprises, so that the storage and mixing cycle of pulping materials can achieve uniform mixing, and prevent pulping delamination or precipitation.As for sizing of slurry, it plays an important role of stirring and mixing.

Low Density Cleaner/Centricleaner

Low Density Cleaner/Centricleaner it is mainly used to remove heavy impurities in the pulp and some light impurities.

Vibrating Screen

Vibrating screen mainly used to select pulp roughly. With steady pulp box and pulp receiving groove, this machine is full closed and has some advantages of firm structured, long operating life, convenient in maintenance and so on.

Refiner

The equipment is mainly used for coarse beating, refining and re-pulping of broke and waste paper.
