Product Description

Product Description

The dryer cylinder for paper machine is a key part of paper drying.
It is used in drying part of a paper production line. Working with hot steam from steam boiler, dryer cylinder dry wet paper sheets, then the dry paper sheets can be reeled into jumbo rolls.
The function of the dryer is to dry the moisture in the paper and finish the paper surface.

All  dryer cylinders, heads and journals are made of special cast iron. Separate journals are bolted onto the dryer heads. Dryer shells are ground on the outside and turned on the inside. All dryer journals with steam or condensate pipes have insulation sleeves. The inner surfaces have grooves for the stationary siphons. The front side ends of all dryers contain manholes.
Cast iron material are excellent in durability. This is because the free form flake graphite in the cast iron material ensured its high corrosion and erosion resistance. The cast iron also has good fatigue strength under the pressure roller forces. At the same time, cast iron itself has a good surface performance, does not need metal spraying treatment like steel dryer.

Drying cylinders for papermaking machinery can produce various specifications of drying cylinders with a diameter of 800MM-4000MM. The material is made of wear-resistant alloy cast iron with high-precision grinding technology. Passed ISO9001-2000 quality management system certification, CE EU product certification, and on-site inspection by SGS, an internationally recognized authority.

Dryer Cylinder Turbulators
The purpose of the turbulators is to destroy the condensation water ring formed in the dryer at high speed and generate more turbulence. The turbulators is installed on the inner surface of the dryer. It rotates with the dryer at the same speed, so it will move the water ring to produce turbulence, which is conducive to heat conduction.
Separate design, with light weight, and convenient and quick forinstallation.
High radial and axial strength in overall structure.
Ensuring maximum instaation firmness.

Dryer cylinder Siphon
In order to ensure the smooth discharge of condensed water in the dryer and avoid flooding; Make the cylinder surface temperature as high as possible to improve the drying efficiency; In order to reduce the temperature difference on the cylinder surface and make the moisture content of the paper uniform, the selection of siphon becomes the key.
Dryer drainage siphon is basically divided into two forms: fixed type and rotary type. The fixed siphon is fixed on a certain point outside the dryer and does not rotate with the dryer; The rotary siphon is fixed in the dryer and rotates with the dryer.

Dryer Cylinder Rotary Joint
The dryer needs steam, and the internal condensate needs to be discharged. But the dryer is a rotating cylinder, so a special joint is needed to complete this task, that is, the steam joint.
Steam in and condensate out are usually completed by a rotary joint at one end of the dryer, or steam in and condensate out at one end.

The wet paper from the press section passes through a drying section consisting of a series of dryers . The steam heat in the dryer is transferred tothe web through the cast iron shell , so that the web is heated and dried . The paper sheet is
tightly covered by the drying fabric on the oven, so thatthe paper sheet can contact the surface of the oven better, thus strengthening the heat transfer process.
