Mixed Plastic Shredding Material Sorting Machines: An In – Depth Exploration

In the context of increasing environmental awareness and the growing demand for sustainable plastic recycling, mixed plastic shredding material sorting machines have emerged as crucial equipment. These machines are designed to separate different types of plastics from a mixture of shredded plastic materials, enabling the effective recycling and reuse of plastic resources. This article will comprehensively introduce mixed plastic shredding material sorting machines, including their working principles, types, applications, advantages, and price ranges.

Working Principles of Mixed Plastic Shredding Material Sorting Machines

Electrostatic Separation Principle

Many mixed plastic shredding material sorting machines use the electrostatic separation principle. These machines are suitable for various types of mixed plastics that are difficult to separate by density flotation methods. They can sort ABS/PS/sinking PP, flame – retardant ABS/PS, PET, PVC, PA, PE, and other plastics. The crushed particles can achieve a single – pass sorting accuracy (purity) of over 95% in a single pass, and can approach 98% after two or three times of sorting. The particle size of the material has a strong influence on the voltage selection. Different particle sizes require different voltages for separation. Therefore, before the material enters the main separation unit, it is necessary to crush it to make the separation effect reach an ideal state. Core components often use imported brands, which can effectively increase the added value of the product. For example, some electrostatic plastic sorting machines use ABB motors, EASYCON PLC control systems, WINPARK temperature – control systems, Kunlun domestic touch – screens, and YIJIA industrial control relays. The control part uses PLC and an 11 – inch touch – screen, making the operation more user – friendly.

Near – Infrared (NIR) Spectral Sorting

Near – infrared (NIR) sensors measure the spectral response of plastic materials. Each type of plastic has a unique response in the near – infrared spectrum, allowing the machine to distinguish between different plastics. For example, an NIR sensor can measure the spectral response of plastic materials. The sensor data is processed to identify the type of plastic and sort it accordingly. The US NRT company’s NIR sorting machine combines diffuse reflection and transmission technology to collect spectral information, which can improve the accuracy and purity of sorting.

Color Sorting

Color sorting machines use high – speed, high – sensitivity linear array CCD as sensors for material color and shape. The basic working principle of these color sorters is to feed the material from the feeder, making the material pass through the observation window evenly. The CCD camera collects the color and shape information of the material, and after image processing, threshold selection, the machine can remove bad materials through a high – frequency solenoid valve. These machines can achieve a sorting accuracy of over 99% when sorting plastics such as ABS, PC, PE, and others.

They can accurately distinguish between different types of plastics based on their unique spectral responses. These machines are suitable for sorting a wide range of plastics, including those with similar colors or physical properties. For example, they can sort PET, HDPE, PVC, and other plastics with high precision.

Color Sorting Machines

Color sorting machines are designed to sort plastics based on their color. They are relatively fast and can quickly separate plastics of different colors. However, they may be affected by factors such as light conditions and surface contamination. They are often used in combination with other sorting methods to improve the overall sorting accuracy.
