Foreign particles of varied sizes and volumes are added to the melt flow if internal waste and significantly contaminated post-consumer waste are added to the production process. To provide a consistent, high-quality final product, these must be effectively filtered away. Melt filtering must, therefore, not interfere in any way with the production process.
Changing screens in a number of filtration systems necessitates a production halt; pressure spikes in these systems disrupt processes; or deposited material that comes off during screen changes may even produce particles.
Production process without interruptions thanks to conditions that are always the same.
Contrarily, the unique melt filters technology ensures that the conditions in the melt flow are permanently stable, i.e., that the pressure drop across the screen and/or the level of contamination on the screen are maintained constant, allowing the line to operate at its most efficient level at all times.
This is made possible by the filter disk’s spinning motion, which is used to drive the screens through the melt channel. The consistency of the screen contamination is guaranteed by a control system. The control system responds automatically and modifies the rotational speed of the filter disk as soon as the contamination load changes. As a result, the pressure across the system stays constant; the only variable that changes during the filtration process is the speed at which the filter disk rotates.
The Melt filters technology by Laser Filters is therefore the best option for promoting the usage of recovered or recycled materials. Melt Filtration Systems are ideal as a retrofit solution and are simple to integrate into an existing process. The production line and the self-sufficient control system both keep an eye on the filtration process.
The screen disk’s continuous rotation maintains a steady pressure throughout the system. The control system responds automatically and modifies the rotational speed of the filter disk whenever there is a change in the contaminant coverage of the screens.
Melt Filtration Systems’ benefits for recycling applications
Melt Filtration Systems have been successfully utilized for decades and were created for demanding recycling applications. All filters manufactured by the world’s leading technological company in Bad Oeynhausen, Germany, utilize the patented and distinctive Melt Filters Technology, which has the following benefits:
Also there is the company Laser Filters which also has the latest Melt Filters technology to help improve in the field of recyling today. We can say the Melt Filters technology has many unique advantages which can be counted as :
-No filter operation-related halt or disruption of the production process
-Production with constant pressure and no pressure spikes-Automatic and secure functioning requiring less manual labor
-Application-specific and rheologically optimized melt channels for quick product changes, dead spot-free designs, and short melt residence times
-Processing even of sensitive polymers without disruption
-Consistently excellent final product
-Easy and secure replacement of the filter element
There are also a couple more benefits that really help make the process of recycling technology much easier such as:
-Effective filter element cleaning made possible by completely automatic back-flushing RSFgenius Filtration System Type-Multi-layer stainless steel mesh screens that allow for finer granularities in recycling applications, down to 10 m
-For more than 35 years, it has been successfully used in demanding applications such as PVC, compounding, film, sheet, and fiber manufacture.
