Condition: new, Year of construction: 2026, functionality: fully functional, power: 198 kW (269.20 HP), Plastic squeeze dryers / Agglomerators are a vital part of plastic film washing lines. Chodowg Sgcspfx Agkoa Washed films retain up to 40% moisture normally after exiting the wash process. High humidity will be affecting the efficiency and production of the following extrusion pelletizing process. Having a plastic squeeze dryer/Agglomerator is a must to dehydrate the washed film and increase the density of recycled film and fibre material. This also will increase the capacity of the extrusion process and further refine the quality of final plastic pellets. Even the water-washed plastic film processed through a spin-dryer still contains over 10% moisture which would be uneconomic to agglomerate on a conventional batch agglomerator. By redusing the moisture so significantly the productivity of the extruder and quality of pellets is increased exponentially. The latest development for drying and simultaneously agglomerating washed film are plastic film squeeze dryers which could reduce moisture to the minimum and the resultant squeezed material only contains maximum 3%, and more usually 1%, residual moisture. Much cheaper to operate than hot air drying where materials are still in lightweight flake form, and better result as the output materials are continuously agglomerated direct from washing lines with +40% fluids on entry to the dryer, to output dense free flowing agglomerate. In this form it is not necessary to have cutter compactor extruders saving more energy, as the materials are so dry and dense they can be fed direct to extruders for pellet production. With over 30 years of producing recycling dryers and extruders GENIUS have sold more than 600 of these driers to the plastics recycling market. ..There are 4 models in the range with production between 250 kgs per hour up to 1200 kgs per hour.
