Mixed Plastic Separation Machine
Efficient equipments for plastic sorting
Mixed plastic separation machine is suitable for all kinds of hybrid plastics that are difficult to sort by density flotation. Such as PET/PVC, ABS/ PS / PP, PC/PA, ABS/PA, ABS/PC , ABS/HIPS, PET/PC/PMMA, PP/PE, etc.
Plastics are durable, lightweight and inexpensive materials. They can readily be molded into various products which find uses in a plethora of applications. Every year, more than 420 million tons of plastics are manufactured across the globe. Consequently, the reuse, recovery and the recycling of plastics are extremely important.
Plastic sorting is an important step in the plastic recycling process. There are six kinds of common plastics: PS (Polystyrene), PP (Polypropylene), LDPE (Low-density polyethylene), PVC (Plasticised Polyvinyl chloride or polyvinyl chloride), HDPE (High -density polyethylene), PET (Polyethylene terephthalate), etc. In order to recycle plastics, it is necessary to separate plastics according to different materials.
Mixed plastic electrostatic separation machine
Our mixed plastic separation machine adopts the electrostatic separation method, apply to process the mixed plastics which are difficult to be separated by the density flotation method. Such as PET/PVC, ABS/ PS / PP, PC/PA, ABS/PA, ABS/PC ,ABS/HIPS,PET/PC/PMMA, PP/PE, and other plastics in different groups, the separate ratio accuracy can be up to 99.5%.
Working process of mixed plastic sorting machine
As the input size will make the big difference for the charge, the uniformity and weight of the feed stock also will affect the separation process. If the feed stock is in a very bad state with big differences, better to be screened into different sizes to get the high separation rate.
So the collected mixed plastic needs to be shredding first, and the waste mixed plastic after the shredding can be cut into particles of 1-2 cm size. Because the plastic itself contains a small amount of moisture, the plastic is dried after it is shredding.
The dried plastic can be sorted in a closed high voltage electric field according to different conductivity. The electrical properties generated by the high-voltage electric field attract plastics of different electrical properties. According to the principle that the same electrical properties are mutually exclusive and different electrical properties are attracted to each other, different electrical plastics are completely separated. Our mixed plastic separation machine has very high separation rate, the primary crushing separation rate is higher than 95%, then the secondary electrostatic separation rate can reach to 100%.
We are experts in the field of solid waste recycling especially metal recycling. We can provide a complete set of solutions, including waste cable recycling, waste circuit board recycling, metal and non-metal crushing and sorting, mixed plastic recycling, etc. If you have any need of our machine, feel free to contact Gomine Machinery.
