On March 11, PAPEL TANGARÁ’S Yankee Cylinder was shipped.
It is a Smart Yankee Dryer cylinder, made of Steel.
Some data
Diameter: 4,880 mm (16’)
Face: 3,120 mm
Made of Steel
Welded heads
Grooved internal surface
With 6 condensate collectors
Operating pressure: 10 bar
The Cylinder was assembled in PAPEL TANGARÁ’S new MP2, which is in the installation phase.
The machine, which is being totally supplied by HERGEN, is the EVO 16 model and was designed to run at up to 1,600 m/min and produce 60 t/d.
High performance with energy saving
Paper production consumes a lot of energy. In a Tissue paper machine, the drying process is responsible for about 70% of the machine's energy consumption. This means that a more efficient drying system results directly in significant energy savings.
Hergen Smart Yankee Dryer is made of Steel. Due to the mechanical properties of this material, its thickness can be significantly less than the ones made of Cast Iron, increasing the heat transfer by up to 35%, resulting in lower energy consumption for the same production.
Hergen quality
NO rupture risk due construction in carbon steel
Increase production: HIGHER HEAT TRANSFER UP TO 35% AS COMPARED WITH CAST IRON CYLINDERS resulting in higher paper evaporation ratio
Innovative condensate extraction system
Higher reliability with no risk inherent to the casting process, such as porosities or discontinuities
Two construction options for Head Covers: mounted with capscrew or welded to the cylinder shell
Metal surface with high hardness resulting in better creping quality
Excellent temperature profile
Steel plate material allows cylinders construction with any required diameter
Easy transportation: journals may be transported disassembled thus reducing the maximum load height
