SPIRALLY LINKED DRYER SCREENS

The spiral dryer screens are specially engineered paper machine clothings for the dryer section in the Paper Mill. The unique seamless spiral dryer screens are ideal for the dryer section where a seam is unacceptable. It is easy to install and repair as it is a chain of spiral loops and hence reduces downtime & increases productivity. These spiral screens are made up of hydrolysis resistant monofilament yarns & have excellent tensile strength & wear resistance. Shalimar has two types spiral screens.

Within a spiral and between two connecting channels, another channel forms, which is called filling channel. To reduce the air permeability filler wires are inserted into these remaining cavities. Because of this, the unfilled spiral screens have higher air permeability than filled spiral screens. The value of air permeability in stuffed spiral screens depends on the size of the cored wire used.
