Melt Filters

Due to the increasing production amounts, plastic wastes emerging in different industries are increasing day by day. Before the awareness of environmental awareness and, more importantly, its responsibility was a necessity, these plastic wastes were stored in an area and were not reused in any way. In fact, some companies unfortunately left these plastic wastes to nature. This posed a serious threat to the environment.

Fortunately, thanks to the legal regulations regarding the environment, the awareness of both protecting the nature and providing economic recovery has become widespread.

What is Recycling?

Recycyling is actually a reprocessing process and requires high technology, knowledge and experience. The recycling process of plastic begins with the purification of plastic from visible foreign materials. Then the plastics are separated according to their type, that is, they are categorized. Afterwards, they are shredded in crushing machines so that the shredded plastic is called bran. Bran is a semi-product of recycling and must be obtained without damaging the intrinsic quality of the plastic. The bran, which has passed through the washing and drying processes in order to increase the quality, is reprocessed after this point. In fact, this is kind of like the remanufacturing of plastic and requires precision technology.

Plastics, which are separated according to their usage areas and turned into bran, are melted and fused at the appropriate temperature in agromel machines. Filtration, which is the next step for melted plastic, is a very critical step. Because it is a stage that requires high technology, where molten plastic is separated from invisible foreign materials.

This separation is done with the Laser Filtering Machine and there is a filtering machine specially developed for this separation. As the molten plastic passes through this machine, it is compressed by two disc-shaped filters. As a result of this compression, invisible foreign substances come to the other surface of the filters. While the filtered clean plastic continues on its journey to be granulated, the waste materials are taken into another container.

Although the surfaces of laser filters appear almost flat, they are porous. In this way they can filter invisible foreign substances.

Laser filtration stage is actually the most important recycling step, as it is a kind of disinfection stage of plastic. It requires high technology and knowledge. The laser filtration machine has heat resistances to maintain the melted state of the plastic. Its two circularly moving blades can rotate 180 degrees and its rotation speeds can be adjusted. There is a water cooler installed to the output of the screw hub to get semi melted output fraction. Depending on ΔP, PLC system decides the rotational speed of sweeper blades and hub-screw dirty fraction discharge mechanism.

Considering all these features of the system, the quality of the recycled plastic output that can be used in all areas depends entirely on the laser filtration system. Otherwise, the entire recycling process will be wasted. In order for the laser filtration machine to work efficiently and without errors, laser filters must be replaced regularly with the new ones.
