WATCH: hamos EKS Black Plastic Separation
Hamos EKS electrostatic separators make use of the differences in tribo-electric behavior of individual plastics. The plastic mixture is fed via a vibrating conveyor into a tribo-electric charging unit. Different plastics are charged here according to the specific properties of the material, taking on either a positive or negative charge. After charging, the mixture enters a high-tension field where the components are separated electrostatically into pure sorted fractions, determined by their different charges. Positive particles are attracted by a negative electrode, while negative particles are rejected and vice versa.
With the hamos EKS you can separate mixed plastics waste into individual fractions using electrostatic separation, as well as separate out undesired plastic contamination. The hamos EKS takes advantage of the differing tribo-electric properties of different plastics, separating these materials into 99.5% pure sorted fractions. This allows recycled mixed plastics waste to be used as quality raw material in new high-grade products. For proper processing, hamos systems require a few different parameters to work best. There must be two distinct and separate materials in the mixture (no composites), the material must be dry, dust free, and have a particle size of ~10mm.
