Product Description

Product Description

The Yankee Dryer is the key component of modern high speed tissue machinery,which structure has been constant innovated,make the tissue machinery is possible to realize the higher speed,higher width and the quality papers.
Our design Yankee Dryer,absorb the foreign advanced technology concept,adopt U groove structure for the internal surface of shell,strengthen its rigid,make the heat transfer area enlarge,reduce the thickness of condensate film,and improve the drying efficiency.

 

Drying principle

The saturated steam introduced from the steam joint is condensed inside the dryer cylinder, and the heat released
causes the temperature of the dryer cylinder to rise,so as to heat the paper sheet coated on the surface of the roller shell.
Heat is transferred to the paper in contact with the surface of the paper and the dryer. 

Steam condenses to produce a large amount of condensed water after the heat is released from the steam.
These condensed water is attached to the inner surface of the dryer by centrifugal force due to the rotation of the dryer,
and forms a water ring at a high angular velocity, which hinders the transfer of heat to the dryer surface.
Siphon condensate will be promptly discharged.
When the speed is low will not form a water ring, but there will be condensation in the dryer splash, accumulation.  

Features

Dryer Cylinder Casting workshop:
1. Hot blast Cupola(3T/h,8T/h)and medium frequency furnace (10)duplex melting .
2.Dryer Cylinder Casting Workshop The resin sand production line with capacity of20T/h.
3.The spectrum analyzer guarantees the quality of your products.

Dryer cylinder Machining workshop: 
1.More than 40 sets of jumbo machine tools for turning,milling,shaver,grinding,drilling.
2.Maximum Diameter of dryer cylinder : 4000mm
Maximum length of workpiece :12000mm
Maximum balancing capacity : 50tons.
 

Advantages

1.The shell is thinner,ensure the more heat to transfer(Evaporate rate).

2.Better elasticity,stronger compressive resistance,which have enough security coefficient for heat shock,machinery fault and potential explosion etc hazards.

3.The surface metal spraying adopts advanced foreign technology and equipment,increase service life.

4.The metal coating of surface can reinforce the chemical coating and wrinkling.

5.No bolts heads to block,can improve the papers stable performance.

6.During operating,the shell thickness is reduced and the metal coating is fall off,which not affects the using performance.

7.Since the date of installing can be put into operating,don't need to run-in with the host,its performance will not reduce as the service life is growing.
