Novel recycling system for mixed plastics from electronic waste
Clean ABS, PS and PP with hamos KRS
Large quantities of mixed plastics arise when recycling electronic waste (WEEE – Waste Electrical and Electronic Equipment) or automotive shredder residue (ASR). The materials contained here, such as ABS, PS and PP for example, are so heavily contaminated by other plastics, wood, elastomers and metals that further processing is not possible without additional treatment.
The hamos KRS recycling system separates out pure plastics from WEEE or pre-treated ASR fractions. The equipment runs entirely automatically und has been designed for three-shift operation. The processing method of the hamos KRS system is so flexible that the most widely different mixtures of plastics can be separated.
The previously broken up mixture of plastics, having been freed from large metal pieces, is classified in a first stage of the treatment process and the light fraction separated out. The plastic fractions are separated from each other according to their specific weight in the subsequent wet separation stage. The ABS-PS and PE-PP concentrates recovered here are then mechanically and thermally dried.
hamos KWS series electrostatic separators separate the remaining metals and other conductive contamination, such as for example rubber and wood, in the subsequent dry separation stage. Downline hamos EKS electrostatic separators convert the mixed plastics fractions, consisting of ABS-PS or PE-PP mixtures, into clean single fractions.
Further separation of rubber and elastomer particles by means of a hamos RSS series separator provides an additional increase in the purity of the end product. When needed, even more specific light coloured plastics fractions can be produced by using optoelectronic sorting equipment.
About Hamos GmbH Recyclingtechnik
hamos GmbH Recycling- und Separationstechnik supplies equipment and systems for recycling and separation of plastics, cables, electronic waste, composite materials, minerals and many other types of materials. A particular focus at hamos is production and consistent further development of electrostatic separators for widely differing mixtures of products. Electrostatic separators are, for example, used in particular for sorting of plastics (hamos EKS) metal-plastic separation (hamos KWS) or mineral sorting (hamos EMS). Electrostatic separators provide satisfaction here through their highest level of efficiency and product purities. Aside from production and sale of electrostatic separators and lines for sorting and recycling, hamos attaches particularly high importance to research and development. Not only can additional application areas for the separators be therefore continually opened up, but especially also complete solutions for complex separation tasks developed. Aside from specific custom recycling solutions, hamos also offers turnkey recycling systems to process used PVC windows (hamos WRS), an electronic waste recycling system (hamos ERP) or a system to recover clean plastics from residual electronic waste (hamos KRS). The company is active mainly on a worldwide basis and presently has around 30 employees.
