In core scenarios such as solid waste resource utilization and waste sorting, air separators, as key equipment for separating light and heavy materials, directly determine the purity of recycled resources and project profitability based on their sorting accuracy, operational stability, and environmental adaptability. Zhengzhou Zhongcheng Environmental Protection Equipment Co., Ltd. (hereinafter referred to as "Zhongcheng Machinery"), based on practical experience from thousands of solid waste treatment projects, has launched its latest air separator. Through intelligent control, structural optimization, and process innovation, it has completely solved the pain points of traditional equipment—"fuzzy sorting, easy clogging and damage, and serious pollution"—making it the industry's preferred equipment. The following section, combining technical details and practical cases, comprehensively analyzes its core features and advantages.

Core Technology Breakthrough: 

Intelligent Control and Precision Design Create a Barrier to Sorting Accuracy

Zhongcheng's latest air separator uses "dynamic adaptation + precise air control" as its core technology. Through aerodynamic optimization and intelligent upgrades, it achieves efficient separation of light and heavy materials, with sorting accuracy and stability far exceeding similar products in the industry.

1. Intelligent Variable Frequency Air Separation System, Real-Time Adaptation to Material Fluctuations

Addressing the fatal flaws of traditional air separators—fixed wind speed and sensitivity to material changes—Zhongcheng's latest air separator employs dual-stage/multi-stage variable frequency air separation technology, constructing a closed-loop control system of "sensing-adjustment-execution." The equipment is equipped with high-precision material sensors and variable frequency fans, enabling real-time monitoring of feed rate, material moisture, and composition changes, and immediate adjustment of wind speed and volume: when processing lightweight plastic films, it automatically activates a low wind speed (5-8 m/s) for precise peeling; when separating medium-weight materials such as paper and plastic sheets, it switches to a medium-to-high wind speed (10-15 m/s) to ensure thorough separation. This dynamic adaptation capability keeps the sorting accuracy consistently above 95%, a significant improvement over traditional equipment (80%-85%). Data from a construction waste disposal site in Henan Province shows that after adopting this system, the residual amount of lightweight materials in recycled aggregates decreased from 3.5% to 0.8%, and the aggregate sales price increased by 40 yuan per ton.

2. Aviation-grade air duct design for a stable and controllable air curtain. Uniform airflow is the core guarantee of sorting accuracy. Zhongcheng Machinery uses fluid dynamics simulation software to optimize the air duct curve thousands of times, creating an aviation-grade streamlined air duct structure. The inner wall of the air duct uses a smooth, wear-resistant coating, combined with an arc-shaped guide plate design, to create a laminar "uniform air curtain," avoiding the sorting trajectory deviation problem caused by turbulent airflow in traditional equipment. In bulky waste processing scenarios, this design can accurately separate sponges (density ≤0.3g/cm³) from heavy wood (density ≥0.6g/cm³), with a separation purity of over 92%, solving the problem of "mixing of light and heavy materials" in traditional equipment.

3. Negative pressure sealed structure for environmentally friendly, dust-free operation. Environmental compliance is a basic requirement for modern industrial equipment. Zhongcheng's latest air separator adopts a fully enclosed negative pressure sorting design. The main body of the equipment, along with the inlet and outlet, are equipped with elastic seals. Combined with a negative pressure settling chamber and dust collection interface, this keeps the dust concentration below 10mg/m³ during operation, far below the national "Integrated Emission Standard for Air Pollutants" (30mg/m³). In municipal solid waste sorting lines, the equipment can be directly connected to a deodorization system, effectively controlling odor diffusion and significantly improving the comfort of the work area. A waste resource recovery project in Shanxi reported that after implementing this equipment, dust complaints in the workshop dropped from 8 per month to 0, and employee job satisfaction increased by 60%.

Scenario Adaptation Upgrade: 

Customized Design Solves Sorting Challenges in Multiple Industries

Zhongcheng's latest air separator is designed with a "modular + customized" concept, providing customized solutions for different material characteristics and operating conditions, covering diverse scenarios such as construction waste, municipal solid waste, and bulky waste.

1. Construction Waste Processing: Wear-Resistant and Clog-Proof, Suitable for High-Impurity Environments

Construction waste is characterized by its complex composition, sharp impurities, and fluctuating moisture content. Traditional air separators are prone to problems such as duct blockage and component wear. Zhongcheng's latest air separator specifically utilizes high-manganese steel wear-resistant liners and an anti-winding structure: the duct and material contact areas are lined with 12mm thick Mn13 wear-resistant steel plates, offering 5 times the wear resistance of ordinary steel; a built-in elastic cleaning device automatically removes adhering concrete residue, making it suitable for humid environments with a moisture content exceeding 30%. In a 100-ton-per-hour construction waste sorting line project in Henan, this equipment operated continuously for 12 months without failure, achieving a stable light material separation efficiency of 96% and a recycled aggregate purity of 98%, directly supplying local building material factories for premium sales.

2. Municipal Solid Waste Sorting: Multi-Component Separation Enhances Resource Value

Municipal solid waste contains a wide variety of light materials (plastic film, paper, wood chips, etc.), making it difficult for traditional equipment to achieve precise grading. Zhongcheng's latest air separator adopts a dual-drum separation structure, achieving simultaneous separation of light, medium, and heavy components through multi-stage wind speed gradients: the first stage separates lightweight plastic film, the second stage separates paper and wood chips, and heavy impurities settle directly. A single unit can simultaneously produce three types of high-purity recycled raw materials. After applying this equipment, a resource recycling base in East China saw its PET plastic recycling purity increase from 82% to 95%, and the sales price per ton rise by 20%; the wood fiber recycling rate increased by 40%, generating an additional annual revenue of over 800,000 yuan.

3. Bulky Waste Dismantling: Flexible Sorting Adapts to Heterogeneous Materials

Bulky waste (furniture, appliances), after being crushed, contains various heterogeneous materials such as sponge, fabric, metal, and wood, making sorting extremely difficult. Zhongcheng's latest air separator features an adjustable airflow angle design, integrated with magnetic separation and eddy current separation equipment to form a unified system: for ultralight materials such as sponges, the airflow angle is increased (30°) for rapid separation; for medium-heavy materials such as wooden components, the angle is decreased (15°) to ensure thorough separation. In a municipal bulky waste treatment project, this system processes 30,000 tons of waste annually, successfully recovering 6,000 tons of metal and 2,000 tons of recyclable plastics, achieving a comprehensive resource recovery rate of 90% and generating nearly ten million yuan in economic benefits annually.

Prominent Operational Value: 

Low Energy Consumption and Durability Reduce Total Life Cycle Costs

Zhongcheng's latest air separator, through structural simplification and material upgrades, achieves "low energy consumption, low maintenance, and long lifespan" while ensuring high performance, significantly reducing customer operating costs.

1. Low Energy Consumption Design, Significantly Reduced Operating Costs

The equipment adopts a high-efficiency energy-saving fan + intelligent frequency conversion control, reducing energy consumption per unit processing volume by 20%-30% compared to traditional equipment while ensuring sorting accuracy. Taking a production line processing 300 tons of municipal solid waste per day as an example, Zhongcheng's air separator consumes only 80kWh of electricity per day, saving over 14,000 yuan in electricity costs annually compared to similar equipment (120kWh). Furthermore, the equipment requires no additional airflow or filtration systems (except for special requirements), reducing initial investment costs by over 15%.

2. Modular Structure, Significantly Improved Maintenance Ease The equipment adopts a fully modular design, allowing for quick disassembly and replacement of core components (fan, sorting drum, seals). Combined with its "few easily damaged parts" structural advantage, annual downtime due to failure is reduced from 120 hours with traditional equipment to less than 20 hours. Zhongcheng Machinery's 24-hour response service and readily available spare parts inventory can control repair time to within 4 hours, further reducing the risk of production interruptions. A waste treatment plant in Shanxi reported that the annual maintenance cost of the equipment is only 12,000 yuan, a 65% reduction compared to the previously used traditional equipment (35,000 yuan).

3. Plug-and-Play Design, Doubling Installation and Commissioning Efficiency

Addressing customers' need for "rapid production launch," Zhongcheng's latest air separator adopts an integrated electromechanical design. Pre-assembly and commissioning are completed before delivery, requiring only connection to power and material conveying pipelines on-site for operation. The installation cycle is shortened from 7 days for traditional equipment to 2 days. For mobile sorting projects, the equipment can quickly adapt to containerized factories, achieving "flexible site switching and immediate production operation," greatly improving project preparation efficiency.

Zhongcheng's latest air separator's core competitiveness stems from a three-dimensional system: "intelligent air control ensures accuracy, customized design adapts to various scenarios, and low energy consumption and durability reduce costs." Through variable frequency air separation and precision air duct design, it overcomes the technical bottleneck of "fuzzy sorting" in traditional equipment; with its wear-resistant and anti-clogging structure and modular configuration, it solves the problem of adapting to various industry operating conditions; and with its low energy consumption and easy maintenance, it creates significant economic value for customers. Driven by the "zero-waste city" construction and circular economy policies, Zhongcheng's latest air separator is becoming the core equipment choice for solid waste resource utilization projects due to its technological innovation and deep adaptability to various scenarios, helping enterprises achieve the development goal of "win-win for both environmental and economic benefits".
