Continuous screen changer BKG® HiCon™ K-SWE-HD/RS

polymer

The BKG® HiCon™ K-SWE-HD/RS recycling filter enables processing highly contaminated recyclates in your blown film application without line shutdowns. Producing quality blown film is not an easy task. A film bubble reacts sensitively to altering process conditions, and only minor changes in temperature, viscosity, and especially pressure can harm the final product. But adding recyclates to the mix is an additional disruptor to an already delicate process. Especially pressure fluctuation during screen change, backflush, and venting can lower the quality of the film or even result in line shut-downs. The Challenge of Processing Recyclates in Blown Film Applications Blown film lines work with operating pressures up to 600 bar, and this amazing level of internal forces needs to be picked up by intelligent design. The BKG® HiCon™ K-SWE-HD/RS provides a comprehensive and effective solution for processing recyclates in blown film applications. By ensuring continuous operation, efficient contaminant removal, and stable melt flow, this advanced filtration system empowers you to achieve higher levels of sustainability, improve product quality, and enhance production efficiency. With its innovative design, it allows you to use large proportions of highly contaminated recyclates while ensuring optimal quality and performance. It is capable of maintaining extremely stable pressure conditions even when processing a high proportion of highly contaminated recycled polymers. The melt pressure-controlled venting start ensures sensitive filling of the cavity after the screen change and prevents pressure drops
