Pet bottle flake recycling granulator ,main machine is a twin-screw extruder with excellent mixing performance, good self-cleaning, flexible modular combination characteristics. The unit does not need a complex pre-crystallization drying system, can achieve the ideal pet viscosity control.
The highest quality requirements occur in the bottle-bottle recovery process.In this case, only the Origin of the bottles is defined and controlled,processing practical and economically viable
If the used bottles come from household waste plastic, there is a risk of unknown contaminants.It will also require highly complex sorting and cleaning plants, increasing the cost of bottle flake material.
The main factors affecting the PET bottle flake processing
When processing PET bottle material, may be exist many interference factors, causing further problems.
PET bottle flake into bottle resin need the best quality PET bottle material. Assuming the scrap cleaning and dressing process is operated high efficiently .there are still many technical requirements to be met in order to obtain the scrap that can compete with the pure material in quality. pre-drying, extrusion with vacuum or without vacuum is optional, melt filtration, scrap cutting, crystallization and SSP.
