Against the backdrop of accelerating the construction of "zero waste cities", the resource utilization of construction waste has shifted from policy orientation to market demand. As the core link of the resource utilization chain, the performance of screening equipment directly determines the quality and project value of recycled products. Zhongcheng Machinery has been deeply involved in the field of construction waste treatment for many years. Based on a deep understanding of industry pain points and technological accumulation, the construction waste screening solution created by Zhongcheng Machinery is characterized by "precise adaptation, intelligent efficiency, and green circulation", forming a complete system that combines technological innovation and practical feasibility. This solution not only deeply aligns with the urban environmental protection policy orientation, but also successfully solves many problems such as low efficiency, insufficient resource utilization, and difficulty in meeting environmental standards in the large-scale application of traditional treatment modes in core cities such as Shanghai, becoming a demonstration benchmark for leading industry development.

The core competitiveness of Zhongcheng screening solution lies in its precise adaptability to complex working conditions. The composition of urban construction waste is extremely complex, with various materials such as concrete blocks, brick and tile fragments, waste steel bars, plastic films, and wooden waste mixed together. The hardness, moisture content, and particle distribution of different batches of materials vary significantly, which puts extremely high demands on the adaptability of screening equipment. Traditional screening methods often use standardized equipment to meet diverse demands, which can easily lead to problems such as clogged sieve holes, chaotic grading, and rapid component wear and tear. The Zhongcheng solution breaks this limitation from the source and establishes a full process service model of "material analysis customized design system integration". Before the project starts, the technical team will go deep into the site to collect material samples, analyze their physical properties through professional testing, and design screening processes and equipment structures accordingly. For example, for demolition waste with high reinforcement content, optimizing the anti entanglement structure design, combining elastic screening screens with rotating cleaning devices, effectively avoiding the entanglement and blockage of equipment by long steel bars and wooden strips; For high moisture content slag materials, adjust the inclination angle and vibration mode of the screen surface to improve material dispersion and ensure that screening efficiency is not affected by humidity. This customized concept runs through the entire plan, from the selection of screen material to the planning of system processes, all centered on adapting to specific working conditions, fundamentally ensuring the practicality and stability of the plan.

Intelligent integration is a significant technological advantage of Zhongcheng's solution, which promotes the comprehensive upgrade of screening operations from "mechanical operation" to "intelligent control". Traditional screening equipment relies heavily on manual adjustment of operating parameters. When material properties change, it requires repeated trial and error to find the appropriate operating mode, which not only reduces efficiency but also leads to significant fluctuations in screening quality. The Zhongcheng solution constructs a fully automated closed-loop processing chain through the deep integration of the Internet of Things, sensors, and intelligent algorithms. The multi-dimensional sensors equipped in the system can collect key data such as material flow rate, screen surface pressure, screening purity, and equipment temperature in real time, and upload the information to the cloud management platform in real time. Management personnel can remotely monitor the operating status of devices through computers or mobile terminals, achieving intelligent management with "unmanned" operation. When there are fluctuations in material characteristics, the system can automatically adjust core parameters such as speed and amplitude based on preset algorithms. If an increase in material humidity is detected, causing screen accumulation, the system will automatically reduce the screen speed and increase the amplitude to prevent clogging; When the impurity content suddenly increases, the residence time of the material on the sieve surface is extended to ensure thorough separation. This adaptive adjustment capability significantly reduces the fluctuation range of screening purity and stabilizes the qualification rate of recycled aggregates at a high level. At the same time, the built-in fault warning mechanism of the system can timely detect potential problems such as bearing overheating and screen damage and issue alarms, avoiding downtime losses caused by equipment running with problems and significantly improving production continuity. In the sorting process, the collaborative effect of intelligent modules is also prominent. Equipment such as strong magnetic iron separators and air selection devices are precisely linked with the main screening system to efficiently separate impurities such as metals and light floating objects, achieving targeted recovery of various resources and completely changing the limitations of traditional screening with "coarse separation and low purity", laying a high-quality foundation for subsequent resource utilization.

Green environmental protection runs through the entire process design of Zhongcheng screening scheme, controlling pollution emissions from the source and achieving a harmonious unity of environmental benefits and production needs. The dust and noise generated during the screening process are the core pain points that hinder environmental impact assessments for many projects. Traditional open or semi open equipment often fails to meet the strict environmental standards of cities. The Zhongcheng plan adopts a targeted fully enclosed workspace design, incorporating core processes such as screening and conveying into a closed system, coupled with pulse dust removal devices and spray dust reduction systems, to suppress dust diffusion from the source and keep the workshop dust concentration far below national and local standards. In terms of noise control, multiple measures such as selecting low-noise motors, optimizing equipment shock absorption structures, and setting up sound barriers have effectively reduced operating noise, ensuring that the noise level in the work area and surrounding environment meets urban production requirements, and avoiding disputes caused by noise disturbance in traditional projects. In addition to pollution control, the plan also regards "maximizing resource utilization" as the core goal of environmental protection. Compared with traditional landfill methods, it achieves a triple breakthrough in waste treatment of "reduction, harmlessness, and resource utilization". The screened recycled resources are accurately graded, and aggregates of different particle sizes can be used in various scenarios according to their properties - coarse aggregates can be processed into recycled concrete, permeable bricks and other building materials, fine aggregates can be used for roadbed filling, green planting soil improvement, separated metals can be recycled and reused, and combustibles can be uniformly transported to professional institutions for energy recovery. This "classified recycling targeted utilization" model transforms the original "urban waste" into practical renewable resources, truly practicing the concept of circular economy and helping projects achieve a value transformation from "environmental burden" to "resource wealth".

In terms of core components and system durability, Zhongcheng's solution also demonstrates a profound technical accumulation, providing solid guarantees for long-term stable operation. The hard materials in construction waste cause severe wear and tear on equipment components. Traditional equipment often experiences frequent shutdowns and maintenance due to issues such as screen damage and bearing damage, which not only increases operating costs but also affects production progress. The Zhongcheng solution has significantly improved the durability of the equipment through material optimization and structural innovation. The core screening components are made of composite wear-resistant materials, combined with the high strength of high manganese steel and the impact resistance of elastic materials, significantly reducing the wear rate and extending the service life of the components; The key parts adopt sealed bearing design, combined with intelligent lubrication system, effectively preventing dust intrusion and reducing the occurrence rate of failures. At the same time, the scheme adopts modular component design, and the replacement process of vulnerable parts is simple and convenient, which can significantly shorten maintenance time and reduce the impact on production progress. The project leader provided feedback that after adopting the Zhongcheng scheme, the continuous operation time of the equipment was more than twice that of traditional equipment, and the replacement frequency of vulnerable parts such as screens was significantly reduced. The maintenance cost savings were also significant, fully verifying the durability advantage of the scheme.

The high efficiency and economy at the operational level are important reasons for Zhongcheng's plan to gain widespread market recognition, achieving a win-win situation between ecological and economic benefits. Against the backdrop of continuously rising labor costs, the traditional screening mode relies heavily on manual sorting, monitoring, and maintenance, which not only has low efficiency but also poses high safety risks. The Zhongcheng solution replaces traditional manual operations with intelligent equipment, achieving automation of the entire process from material conveying, screening and grading to impurity separation, greatly improving processing efficiency while significantly reducing labor costs. Compared to the traditional manual sorting mode, the processing efficiency of the intelligent system is improved by dozens of times, and it can operate continuously 24 hours a day, effectively increasing project capacity. In terms of system adaptability, the application of modular design concept gives the solution strong flexibility, which can be flexibly combined according to project scale and site conditions - it can integrate multiple sets of equipment to form a large-scale disposal center, meeting the batch demand for centralized treatment of urban construction waste; It can also be assembled into a mobile screening station to achieve nearby processing of scattered scenes such as demolition sites and infrastructure construction sites, reducing material transportation costs and secondary pollution risks. This' tailored to local conditions' configuration mode enables the solution to adapt to various needs from small and medium-sized projects to large-scale resource utilization bases, greatly expanding its application scope.
