Wind Sifter

With the acceleration of urbanization and the increasing scarcity of land resources, ecological governance and resource utilization of landfills have become key issues for sustainable urban development. As the main target of treatment, the disposal of stale waste is a complex system engineering that integrates environmental engineering, mechanical sorting, and resource recycling. The disposal of stale waste is a systematic project that integrates environmental governance, resource recycling, and land regeneration. Its core goal is to efficiently separate stabilized waste that has been buried for many years under the premise of safety and environmental protection, and achieve maximum resource utilization.Definition and Main Components of Stale WasteStale waste, specifically referring to municipal solid waste that has reached a relatively stable state after long-term (usually 8-10 years or more) anaerobic degradation and physicochemical reactions in landfills. Its original organic components (kitchen waste,

In the field of solid waste recycling and resource recovery, screening equipment plays an essential role. With its unique structure and operational design, the Ballistic Screen achieves high anti-clogging efficiency and continuous screening, making it an ideal choice for construction waste, municipal solid waste, and industrial waste treatment lines.Working PrincipleThe Ballistic Screen mainly consists of a screen box, screen mesh, support structure, and bounce balls. During operation, materials evenly enter the screen surface and move forward with the vibration of the screen body. The bounce balls installed beneath the screen mesh continuously jump with the vibration, striking the bottom of the mesh to create a consistent impact force. This effectively prevents screen blockage and ensures smooth material passage.This design not only improves screening efficiency but also reduces manual cleaning and downtime, allowing the equipment to maintain stable operation over extended periods.Application ScenariosConstr

In the sorting process of the municipal solid waste disposal line, the wind sifter and the ballistic screen are two core devices, and their working principles and applicable scenarios are significantly different. The choice of which one to use mainly depends on the composition of the waste, the pre-treatment processing, and the final sorting target. Below, we will analyze in detail the applicable situations and advantages of both:Wind SifterWorking principleBy utilizing the differences in aerodynamic characteristics (such as density, size, shape, resistance) between materials and impurities (mainly light substances), they are separated through controllable airflow. Light matter is carried away by the airflow, while heavy matter falls due to gravity.Applicable situationsThe sorting target is light debris: when the main purpose is to separate light substances such as plastic film, paper, paper, fibers, and small plastic sheets from the shredded waste.The material has been fully shredded: the waste has been

As the service life of municipal landfills extends, large volumes of aged waste have accumulated in legacy landfill sites. This type of waste, having undergone years of natural degradation and compaction, presents a high degree of complexity in composition and is difficult to process. Despite these challenges, aged landfill waste still retains certain resource value. Given the diverse composition, sorting difficulty, and mounting environmental pressures, the use of professional, high-efficiency sorting equipment has become a critical pathway to achieve the goals of volume reduction, harmless treatment, and resource recovery. In the aged waste treatment process, the trommel screen and wind sifter act as core sorting equipment. Working in tandem, they enable the effective separation and recovery of valuable components from mixed waste streams. Trommel Screen: Efficient Screening for Removal of Soil and Humic Matter Working Principle:Driven by a motor, the rotating cylindrical drum causes waste materials to

The working principle of the wind sifter separator is mainly based on the difference in suspension speed between materials and impurities. It generates strong airflow, effectively sorting out disorderly materials while removing light impurities and dust, as well as removing some heavier impurities such as stones and soil blocks. The wind sifter separator is composed of a supply air system, a return air system, a conveying system, etc. The supply air system and return air system interact to form a regular air flow inside the box, driving lighter materials to be transported forward to the feeding hopper of the conveying system. There are two core elements to achieve its functionality in design:1,High speed airflow blows out light matter;2,Settle and collect light substances through various means.Based on the analysis of the above two points, the influencing factors include wind speed, air volume, particle size, thickness, and light material filtration.

Wind Sifter Separators are devices based on the principle of gravity separation. They separate heavy and light components in materials by utilizing airflow, allowing for precise material classification.
