Product Description

Dryer Cylinder
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.

Dryer Cylinder Spare Parts

 

 

 

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.
