Dryer screen can be classified depending on weaving struction can be devided into WOVEN type and SPIRAL type. 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. Also called as Spiral link dryer fabric or SLDF, spiral dryer screen is assembled with spiral loops linked by a pin yarn inserted in the adjacent holes. Spiral fabrics are widely used in various industries as paper machine dryer screen, drying & conveyor belts, filter cloth or screening media. Excellent materials are adopted to make the spiral fabric to protect against hydrolysis and high temperatures conditions. Depending on the filler wire added to the spiral dryer screen, air permeability range from 100 to 1380 CFM. 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.
