APEX NIR Polymer Sorting Machine for Plastic Flake Resin Separate

APEX Plastic NIR Sorting Machine Features

The PM plastic polymer sorter is a professional basic vertical material sorting equipment specially developed for mixed plastic flake and particle material separation, solving the core industry pain point that traditional color sorters can only distinguish color differences but cannot identify material differences. This model is equipped with exclusive 2D InGaAs core spectral recognition technology, featuring powerful material identification capability that ignores surface color interference. Different from conventional plastic color sorting machines and belt-type whole-bottle sorters, it focuses on targeted purification of same-color but different-material mixed plastic raw materials. It is widely applicable to common plastic types including PET, PP, PE and ABS, covering daily mixed plastic recycling and basic material classification scenarios, with stable and practical core sorting advantages:

1. 2D InGaAs spectral material identification, sorting independent of surface color 

Breaking through the limitation of equipment that only relies on color judgment for separation, the built-in 2D InGaAs spectral detection system accurately identifies subtle material texture, molecular structure and density differences. It completely ignores surface color interference, effectively separating mixed impurities with similar surface color but different material attributes, thoroughly solving the difficult sorting problem of same-color mixed plastic flakes and particles in conventional recycling production.

2. Wide adaptation for daily mixed plastic raw materials

Perfectly adapted to irregular plastic flakes, broken plastic fragments and small mixed plastic particles, it copes with conventional mixed-spec raw material fluctuations in small and medium-sized recycling factories. It supports universal sorting for various daily waste plastic mixtures, realizing one-stop material classification and impurity removal.

3. Stable anti-blockage vertical feeding structure

Optimized for fragmented and granular plastic materials, the exclusive anti-floating and anti-blockage feeding design ensures uniform material dispersion. It avoids material stacking, flying and missing detection during long-term continuous operation, maintaining stable and consistent sorting accuracy for batch production.

4. Cost-effective basic material purification

As the entry-level material sorting model of the series, it features simple structure, low energy consumption and low daily maintenance cost. It upgrades the traditional recycling process that can only rely on color screening, realizing independent material classification and purification with low investment cost, greatly improving the purity and recycling value of finished plastics.

The PM plastic sorter is dedicated to small and medium-sized plastic fine processing factories and conventional mixed plastic regeneration projects. With powerful same-color different-material separation capability and stable universal adaptability, it provides reliable and cost-effective material sorting solutions for basic waste plastic resource upgrading.

Working Principle-How does it work?

Step-by-Step Sorting Workflow:

1. Mixed plastic flakes enter the vertical anti-floating hopper.
2. Vibratory feeder spreads materials for steady single-layer falling.
3. 2D InGaAs sensor reads unique molecular spectral fingerprint of each plastic resin.
4. Processor identifies material differences to separate PET, PP, PE, ABS, PVC even with identical color.
5. High-speed nozzles blow out off-spec plastic impurities based on spectral data.
6. Target qualified plastic falls into the finished product hopper.

Applicable Sorting Materials

PM Series NIR sorting machine is tailored for the classification of mixed granular and flake waste plastics such as PET, PE, PP, PC, PMMA, ABS and PVC. Powered by exclusive InGaAs near-infrared spectral analysis, the equipment identifies the unique molecular spectral fingerprint of each polymer, enabling precise separation of plastics with identical appearance but different internal material properties.

Applications

APEX PM series near-infrared NIR sorting machine targets the core pain point of mixed multi-resin waste plastic recycling. It is widely deployed in post-washing plastic processing lines to sort out foreign plastic impurities from mixed raw materials. From small-scale recycling workshops to large integrated plastic granulation enterprises, PM sorters realize automated resin sorting, effectively upgrading the purity of recycled plastic particles and helping manufacturers obtain higher premium for export-grade recycled plastic materials.
