Municipal Solid Waste Treatment Equipment
What is a Negative-pressure air separator?
The negative-pressure air separator is a precision sorting device commonly used in the field of solid waste treatment. Primarily designed to separate light materials from various waste streams, it is widely applied in the processing of legacy waste, construction and demolition waste, municipal solid waste, and industrial solid waste, serving as a crucial piece of auxiliary equipment for achieving resource recovery and harmless treatment.
Based on the settling behavior of solid particles in air, this equipment achieves efficient separation of light and heavy materials through precise control of airflow and wind speed. It is frequently integrated with crushing, screening, and magnetic separation machinery to form a comprehensive solid waste sorting system capable of accurately separating lightweight combustibles—such as plastics and wood—from inorganic aggregates.
Product Details
The negative-pressure air separator is designed to remove 2D lightweight impurities from granular material (under 10mm in size) at the discharge point of a belt conveyor, thereby increasing the material’s purity.
Key components include the motor, integrated housing, rotary screen, cyclone separator, main steel structure, fan, air ducts, and discharge valve.
Featuring an enclosed design and a dedicated dust removal system, the equipment operates with minimal dust and low noise, meeting environmental compliance standards. It combines high efficiency, energy conservation, and strong adaptability, significantly enhancing the purity of recovered resources and helping to transform solid waste into valuable material.
Applicable to:
Primarily used for separating light materials from waste streams such as aged refuse, this equipment regulates airflow velocity based on particle sedimentation principles to separate light and heavy fractions. Featuring an enclosed design integrated with a dust removal system, it ensures low dust emissions and quiet operation while enhancing the purity of recovered resources. Combining high efficiency with environmental friendliness, it serves as essential auxiliary equipment for the resource recovery and treatment of solid waste.

The material channel is designedin a stepped manner which candisperse the stacked materials andachieve uniform feeding
The negative-pressure air separator offers strong adaptability and efficiently processes various types of solid waste.
Leveraging precise airflow control and variable-frequency speed regulation, it accurately adjusts wind speed and negative pressure to achieve highly efficient separation of light and heavy materials with high purity, effectively resolving the issue of incomplete separation often associated with traditional equipment.
Featuring a fully enclosed negative-pressure design and a dedicated dust removal system, the unit ensures that dust and noise emissions strictly comply with environmental standards, eliminating secondary pollution. Its compact structure, low energy consumption, stable operation, and low failure rate—combined with ease of maintenance—make it ideal for integrated operation with crushing and screening equipment. It significantly boosts the efficiency of solid waste resource recovery while balancing environmental and economic benefits; suitable for diverse sites and processing scales, it is a preferred choice for the harmless treatment and resource utilization of solid waste.
Applications
Application fields: industrial waste, automobile tail crushing material, waste recyclingmaterial, incinerator ash, scrap steel crushing material, home appliance crushingmaterial and other waste mixed materials, to remove wool and soil, sponge and other light objects in the material.
Primary Function:
Typically serving as tertiary screening equipment, the unit utilizes a negative-pressure suction inlet to extract lightweight materials from the feed point. A portion of the aspirated dust is processed through a cyclone separator, collected at the bottom discharge valve, and removed via a collection conveyor. Meanwhile, lightweight materials fall onto a rotating screen; the screen’s rotation conveys them to a discharge valve, from which they are transported out by a discharge conveyor. This process purifies the material, facilitating subsequent downstream processing.
The maximum size for heavy materials entering the equipment is 10 mm, while the size limit for lightweight materials is more flexible. The standard processing capacity is 20–30 tons per hour (depending on material bulk density).
