With the continuous increase in solid waste generation, traditional sorting equipment suffers from low precision, high pollution, and high energy consumption, hindering the process of resource utilization. Zhongcheng Eco Bounce Screen, as a targeted solution, integrates innovative transmission technology and environmentally friendly structural design, demonstrating outstanding performance in the treatment of municipal solid waste and construction waste. This article analyzes its core technology, structural features, and application advantages, showcasing its significant value in improving sorting efficiency, reducing operation and maintenance costs, and contributing to green development, providing a reference for equipment selection and technology upgrades in the industry.

1. Core Technology: The Underlying Logic of Precise Sorting

The Zhongcheng Eco Bounce Screen uses a parallel four-bar linkage + eccentric wheel drive as its core technology architecture. Through the drive motor linking the active shaft, passive shaft, and transmission shaft assembly, the screen plate generates high-frequency reciprocating circular motion. This motion mode enables precise separation of three types of materials based on their size, density, and shape differences: large-particle, high-density 3D materials (such as plastic bottles and bricks) roll along the screen surface to the end discharge hopper due to their strong rebound force; lightweight, flat 2D materials (such as plastic film and paper) are pushed to the side discharge port due to their poor rebound effect; and inert impurities with a particle size less than 10mm (such as sand and food residue) fall directly through the screen holes into the bottom collection hopper.

Its technological breakthrough lies in its dual-axis synchronous transmission design: by linking the drive shafts of rotating shaft one and rotating shaft two, along with anti-vibration support rods and a shock-resistant base, the problem of uneven force on the screen plate caused by traditional single-sided drive is completely solved, improving equipment operational stability by 40% and extending service life to 8-10 years. The triangular prism limiting cross braces welded to the screen plate surface can vibrate and peel off fine materials adhering to the surface of large particles, further improving separation accuracy and enabling a lightweight material sorting rate exceeding 90%.

2. Structural Features: High-Efficiency and Durable Engineering Design

Modular Screening System: Utilizing a large-size, detachable screen plate design, the area of a single screen plate is 30% larger than traditional equipment. Combined with a Y-shaped feed inlet and a multi-channel discharge structure, the processing capacity can reach 100-150 tons/hour, suitable for diverse scenarios ranging from residential waste to large landfill waste. The screen plate and guide plate are integrally molded, supporting manual or automatic adjustment of the tilt angle (0-15°), and can dynamically optimize the sorting path according to the material composition.

Fully Enclosed Environmentally Friendly Structure: The equipment adopts a sealed shell design, equipped with a dust removal and noise reduction system, controlling the dust concentration in the working environment below 30mg/m³ and reducing noise to below 75 decibels, completely solving the dust pollution problem of traditional screening equipment. The internal discharge extension plate and limiting plate structure prevent material adhesion and accumulation, and together with the side-wall vibration motor, effectively handles easily clogged conditions such as moist kitchen waste and sticky construction waste.

Durable Engineering Configuration

The core transmission components utilize a crankshaft structure, coupled with large-clearance bearings and a thin oil lubrication system, reducing wear by 60%. The screen plate is made of 304 stainless steel, offering excellent corrosion resistance and withstanding the impact of sharp stones in construction waste and the acid and alkali corrosion of kitchen waste. The overall frame of the equipment is welded with high-strength steel, exhibiting strong resistance to deformation and maintaining stable operation even under heavy-duty conditions with a daily processing capacity of 1000 tons.

3. Application Advantages: Dual Value of Economy and Environment

Ultimate Sorting Efficiency

Relying on the synergistic process of "mechanical bouncing + intelligent air separation," the Zhongcheng eco bouncing screen achieves an industry-leading level of metal recovery rate >95% and recycled aggregate purity up to 98%. In the Henan aged waste treatment project, this equipment helped increase the resource utilization rate to 90%, and the sorted combustibles were used to produce RDF fuel with a calorific value of 3500 kcal/kg, directly supplying biomass power plants.

Low Energy Consumption and Maintenance Experience: The equipment uses a variable frequency speed control motor, reducing energy consumption by 30% compared to traditional screening equipment. It also boasts high parts versatility, with replacement of easily worn parts like screen plates requiring only 2 hours. Based on statistics from over 500 nationwide implementation cases, its equipment failure rate is less than 2%, and annual maintenance costs are 40% lower than similar products. A construction waste treatment center in Shanxi Province, after adopting this equipment, maintains low maintenance costs while processing 400,000 tons of material annually.

Wide Range of Applications: From separating concrete aggregates from construction waste to extracting lightweight materials from household waste, and removing impurities from kitchen waste, the Zhongcheng eco-friendly bouncing screen covers eight major solid waste treatment scenarios. In Suzhou's "Zero Waste City" pilot project, this equipment, along with drum screens and magnetic separators, forms a modular production line, achieving full automation from crushing to sorting, with a daily processing capacity exceeding 300 tons.

Green Development Empowerment: Its fully enclosed design and low-noise operation allow for direct deployment at treatment stations around urban areas, reducing carbon emissions during solid waste transportation. In a project in Jiangsu Province, plastic film sorted by this equipment achieved a compression density exceeding 500 kg/m³, directly supplying recycled plastic plants and replacing virgin plastic raw material consumption. This reduces CO₂ emissions by 1.2 tons per ton.

Zhongcheng's eco-friendly bouncing screen, with its parallel four-bar linkage and dual-shaft synchronous design, achieves a lightweight material sorting rate of over 90%, solving the accuracy and stability problems of traditional equipment. Its modular screen body, fully enclosed structure, and durable configuration ensure a processing capacity of 100-150 tons/hour while controlling dust, reducing noise, and minimizing malfunctions. In application, it improves resource recovery rates, adapts to multiple scenarios, and reduces carbon emissions, offering both economic and environmental benefits. This equipment promotes the transformation of solid waste treatment towards high efficiency and low carbon emissions, providing strong support for the construction of "zero-waste cities" and serving as an important benchmark for technological upgrading in the industry.
