The hamos WRS window recycling plant is specially designed for the economic recycling of PVC window profile sections and PVC waste windows and consists of a combination of hamos EKS electrostatic plastic separators and opto-electronic color sorting devices.
hamos EKS electrostatic separators are used to separate practically all seals (rubber, soft PVC, etc.) from shredded and dedusted PVC window sections. To further increase the purity and/or improve the degree of whiteness, opto-electronic color sorters are installed downstream.
Through the combined use of these two processes, PVC purities of over 99.99 % can be achieved.
In order to achieve an optimum separation result, the PVC window regrind to be separated should be as follows:
You are not sure whether your material is suitable for electrostatic separation? After consultation, send us a material sample of approx. 20 kg with which we can test the separability of your material in our pilot plant.
We show you which purities and throughputs we achieve with your material. Based on these separation results, you will receive our test report. We will then be happy to offer you the optimum system for your application.
You will be amazed at the added value you can achieve with your material once it has been separated into unmixed fractions.
Step I: Electrostatic separation
In the hamos EKS, the granulated and dedusted mixture of PVC and rubber is tribo-electrically charged in a special charging unit, with PVC particles being negatively charged and rubber and foreign plastics positively charged. The plastics are then separated in a high-voltage field. A special electrode design is used to additionally separate some of the impurities from metal, glass, wood, PE films, etc. that may be contained in the material.
Step II: Color sorting
In order to increase the product purity of the PVC fraction, an opto-electronic SEA PIXEL color sorting system is subsequently used. The material to be sorted is inspected from all sides by a camera system. If a false-colored particle is detected, it is blown out by a fast-switching pressure valve.
For example, if you
recycle, the hamos WRS system is ideal for separating unwanted contaminants such as rubber seals, nylon and other foreign plastics.
