Product description

Huatao has developed a wide range of spiral dryer screen to meet each client's needs helping to reduce operation cost through energy efficient solutions. Spiral dryer screen also called as spiral link dryer fabric or SLDF, spiral dryer screen is assembled with spiral flat yarn loops linked by a pin yarn inserted in the adjacent holes.

Excellent materials are adopted to make the spiral fabric to protect against hydrolysis and high temperatures conditions.

Flat yarn spiral dryer screen composed of flat wire, the surface dryer screen is smoothly, depending on the filling yarn added to the spiral dryer screen, air permeability range from 100 to 1380 CFM.

With its flexible and adjustable permeability and perfect surface, the paper breaking caused by airflow disturbance is greatly reduced, thus improving the production efficiency of paper machine, the flat yarn spiral dryer screen mainly used to the high speed paper machine which required high grade of paper.

The selection of dryer screen is depending on the various paper machine parameters such as paper grades, dryer cylinders configuration, dryer cylinder temperatures, air balance in the hood etc. Dryer screen design and materials are also very important.

For a particular paper machine, the permeability, design and materials of the dryer screen should be adapted to make sure optimum drying from a drying section. The air permeability of the dryer screen has a great impact on the rate of evaporation of water. If the permeability is decreased, then it is reduction in drying capacity of the dryer screen.

The dryer screen, whose air permeability range between 700-1000cfm is used on paper machine for producing higher gsm Kraft and board varieties. On the other hand 100-400cfm dryer screen widely used in medium and high speed paper machine, high numbers of contact areas with the drying surface ensure uniform drying.

Proper chosen of dryer clothing improve paper machine runnability, increased drying rate, improved paper quality and savings energy.

Moreover the dryer screen/fabric/canvas should have the following parameters or characteristics: Aerodynamic Properties, Heat Transfer, Fabric Tension, Sheet Support, caliper, heat resistant, wet-resistant, should be less elongation at heat, durability, silent drive, easy to operation etc.
