Pure plastics with electrostatic separators
With hamos EKS electrostatic separators you can separate plastic mixtures into their components by dry means. hamos EKS separators can also be used to separate unwanted plastic impurities.
By utilizing the tribo-electric behavior of the individual plastics, the hamos EKS separates your mixed materials into unmixed fractions with little effort. You can thus recover valuable raw materials for new, high-quality products from mixed plastic waste.
Requirements for your material
To achieve an optimum separation result, the plastic mixtures to be separated must be as follows:
- Mixture of non-conductors
- Completely digested material (no material composites)
- Different tribo-electric charging behavior
- Dry material (ideal surface moisture less than 0.4 %)
- Dedusted material
- Particle size between 2 and 12 mm
- Ideally two-component mixture
Not sure if your material is suitable for electrostatic separation? Talk to our experts. After consultation, you are welcome to send us a material sample of approx. 20 kg, which we can use to 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 device or system for your application.
You will be amazed at the value you can add to your material once it has been separated into clean fractions!
hamos EKS electrostatic plastic separators utilize the differences in the tribo-electric behavior of the individual plastics for separation.
The plastic mixture is fed via a vibratory conveyor into a so-called tribo-electric charging unit. Different plastics are selectively charged in this unit in a material-specific manner and assume a positive or negative charge. This effect is caused by electron transfers from one particle to another.
After charging, the plastic mixture enters a high-voltage field, where the components are electrostatically separated into pure fractions on the basis of their different charges. Positive particles are attracted to a negative electrode, while negative particles are repelled, and vice versa.
With minor modifications to the charging unit and a readjustment of the separating plates, it is possible to separate different plastics one after the other without much effort. For example, one can separate PET-PVC and then PE-PP with the same machine.

- Other plastic mixtures
the hamos EKS is the ideal device for plastic separation.
Professionals work with professionals
After 21 years of operation, our experience with the hamos WRS window recycling plant is very positive. The plant is an important part of our process. It helps us to achieve our targets. It guarantees the highest quality required for the PVC and thus increases the overall performance of our process. The hamos plant is indispensable and "closes our recycling loop."
- Bodo Streubel, Operations Manager of Dekura Bad Schmiedeberg
We are very satisfied with the standard hamos GmbH has achieved. Previously, it was not possible to sort PVC from profile sections and production remnants fully automatically to this high standard of quality and purity. This development has helped us to completely close the material loop in window profile production. A new world-class standard was born.
- Jörg Ipfling, Manager Recycling Technology Window Solutions at Rehau
The electrostatic recycling systems of HAMOS make a very important contribution to the recycling process of PVC windows due to their good separation performance.
- ppa. S. Lengnick, Production Management, VEKA Umwelttechnik GmbH
The separation systems supplied by hamos are an essential part of ensuring the highest quality of products supplied by Metal-Plast to the market. By using hamos solutions we have increased the processing capacity of our plant and the products manufactured by Metal-Plast are of the highest quality.
