The Intelligent Core of Solid Waste Resource Utilization Technological Breakthroughs and Value Reconstruction of Composite Waste Sorting Equipment

In today’s in-depth advancement of global sustainable development strategies, efficiently addressing the industry pain points of “difficult separation and low utilization” of composite waste has become a key proposition for promoting the implementation of circular economy. A composite waste sorting equipment integrating intelligent sensing, precise sorting, and green energy-saving technologies is redefining the industrial standards of solid waste resource utilization with its disruptive processing efficiency, transforming various mixed wastes from “environmental burdens” into “recycled resources” and becoming a core hub linking green production and circular utilization. Today, we will conduct an in-depth interpretation of this “hardcore equipment” driving the upgrading of the solid waste treatment industry from three dimensions: technological innovation, scenario implementation, and industrial empowerment.

I. Technological Innovation The Intelligent Logic of Precise Sorting

The core advantage of this composite waste sorting equipment lies in breaking the limitation of “extensive separation” of traditional sorting equipment, achieving triple breakthroughs of “precise identification, efficient sorting, and low-consumption operation” through multi-technical integration.

1.Identification Technology Precise Positioning with Multi-Dimensional Perception

The equipment is equipped with a dual system of multispectral recognition and X-ray detection, which can quickly capture the physical properties (density, conductivity, spectral reflectivity) and chemical composition of different materials. Even for mixed particles with a particle size of less than 5mm, it can achieve an identification accuracy of over 99.8%. For composite waste with complex components, the built-in AI algorithm automatically establishes a material database and continuously optimizes the recognition model through deep learning to ensure adaptability to new types of waste.

2.Sorting Structure Efficient Coordination of Modularization

Adopting a modular sorting unit design, it integrates three core technologies: air separation, electromagnetic separation, and vibration separation. Lightweight plastics are accurately separated by adjustable-speed air flow, metal impurities are adsorbed by high-frequency electromagnetic induction, and heavy particles are classified and screened by vibrating screens. Each unit is linked through an intelligent control system, which automatically switches sorting modes according to waste composition. The processing efficiency is 60% higher than that of traditional equipment, and the sorting purity is stably maintained above 99.2%. Core components are made of AISI 316L stainless steel and wear-resistant ceramic composite materials, with a service life extended to more than 8 years, far exceeding the industry average of 3-5 years.

3.Intelligent Upgrade Full-Life Cycle Green Control

Modern versions have achieved full-life cycle intelligent control: the automatic feeding system ensures uniform material distribution through weight sensing and flow control; the central control system integrates industrial Internet of Things modules to support real-time monitoring of sorting efficiency, energy consumption data, and equipment status, and can remotely adjust process parameters; the waste heat recovery device converts heat generated during equipment operation into heating or preheating energy, reducing the unit processing energy consumption to 0.8kWh/kg, with motor power ranging from 11-90kW, meeting international low-carbon equipment standards.

II. Scenario Implementation A Resource Conversion Tool for the Entire Industry

Its application scenarios have covered multiple industrial fields and recycling links, providing customized solutions for different types of waste treatment needs and becoming a key equipment for promoting industrial green transformation.

1.Applicable Wastes From Industrial Scrap to Domestic Solid Waste

• Industrial mixed waste: Electronic waste dismantling residues, automobile dismantling residues, mechanical processing scrap
• Construction and decoration waste: Waste insulation materials, rubber-plastic mixtures in decoration waste, glass fiber waste
• Post-classified domestic waste: Mixed plastics, waste paper-plastic composite packaging, fiber and metal mixtures in waste textiles

2.Process Integration Building a Closed-Loop Recycling System

In the solid waste treatment industrial chain, it is in the core link of “precision sorting”, connecting front-end crushing and back-end resource utilization:

• Pretreatment process: Mixed waste initially processed by crushers and shredders
• Core process: Separating into single recycled raw materials such as plastic, metal, fiber, and rubber
• Subsequent processes: The separated raw materials enter recycling granulation, metal smelting, fiber reshaping and other production lines respectively to achieve high-value utilization

This full process of “crushing → sorting → resource utilization” increases the resource conversion rate of mixed waste from the traditional 50% to over 97%, significantly reducing the amount of solid waste landfilling.

3.Customized Solutions Adapting to Different Scenario Needs
