Pure plastics with electrostatic separators

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

You will be amazed at the value you can add to your material once it has been separated into clean fractions!

Operating principle

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.
