Continuous screen changer for non-woven fabric production line
Why do we need to use the screen changer/ melt filter on the non-woven fabric production line?
In nonwovens manufacture it is necessary to achieve a uniform spinning quality across all spin packs. Therefore, any in homogeneities must be removed before they enter the spinning beam. Moreover, process consistency regarding pressure and temperature is the basic prerequisite for an efficient production. Our GT-DP-R series double-piston continuous screen changer is widely used on spun bond and melt-blown nonwovens production lines
Benifits of this GT-DP-R series continuous screen changer
1, Eliminates line shutdown thus increasing production
2, Leakage-free process
3, Two breaker plates design increases filtration area compared to single breaker plate design
4, Reduced downtime & scrap
5, Reduced inlet pressure at extrusion die
6, Reduced temperature variations in the melt ·
