Roller for Paper Making
Product Description
The press roll is the main component of the press device. There are many types of press rolls, flat roll, vacuum roll, grooved press roll, blind hole roll and controllable medium and high roll. After absorbing the advantages of vacuum pressure roller, groove roller and blind hole roller, several other new types of pressure rollers have appeared. The purpose of developing new press roller is to improve the dehydration efficiency and improve the quality of the paper sheet. Reducing the negative impact of pressing on the paper industry.

Product Detail
Stone roll of paper mill
The press section consists of two rolls of hard and soft rolls, such as stone rolls and rubber rolls, which are combined to form a
set of presses. The press section consists of a press pack of the same or different form, which also customarily includes a vacuum
pipetting device. When pressing, the paper is supported by a cloth of appropriate specifications, which can evenly pressurize the
pressure and take away some of the water squeezed out by the press, and can increase the pressure of the pressurization and
improve the dewatering ability of the press.

Vacuum press roll of paper mill
Vacuum press roll's surface is drilled dual helix aligned holes, holes diameter 4mm,opening rate 12.2% .Roll body is made by SUS304. Vacuum box body, water pipes and connecting parts are all stainless steel.The whole chambers can be taken out for maintenance.The max. suction width is 3850mm, min. suction width is 3430mm. Suction width can be adjusted at operation side.There are air bellow and sealing strip in the roll, air bellow pressure is 0.025~0.07Mpa, with shower inside. Sealing strip material is
graphite rubber. Air bellows and sealing strips are made by Leripa or Aisa Paper Tech.

Curved roller of paper mill
Applied to stretch paper, wire, blanket felt. Roller inside and outside surface will be processed. We will do dynamic balance to improve the stability of the roller.After shaft head installed, we will do dynamic balance again.The dynamic balance will be G1
Rubber roll of paper mill
Special coated material with good Rubber toughness and uniform ;Tapping area up to 50% ,specially designed buffer layer helps
disperse stress and mechanical shock resistance effectively during operating; Excellent dehydration ,low nip pressure which
prevents dandy marks and crushing of paper sheet ;High wear resistance ,chemical resistance . The rubber roller has moderate hardness and elasticity, high oil resistance, washing solvent resistance, wear resistance and shape stability. Soft rolls are generally made of SBR, CR and PU. The surface of the hard stick was originally made of copper and later replaced with polyester resin.

Application
1. The paper machine wire part mainly has a chest roll, a roll roll and a reel roll, and a case roll as a dewatering element. On the return path of the forming wire, there are many rollers supporting the net, and these rolls can be called guide rolls. There are also tensioning rolls and correction rolls. Paper-making rubber rollers are used for rubber rollers for paper-making.
2. A long net paper machine generally has 70 to 80 rubbers rollers. According to the structure, it can be divided into light roller ( flat roller, no pattern on the surface ), groove roller ( groove on the surface of the coating layer ), vacuum roller, movable are roller ( Hollow bending rolls ) and medium and high rolls. They are used for different parts of the paper machine to squeeze water, press , calendar and so on. It is generally made of various SRs (such as PU ).
