Negative-pressure air separator

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.

VARIABLE FREQUENCY CONTROL

Wind speed, wind speed, and wind pressure can all be variable frequency controlled to adapt to different material properties

INTERNAL CIRCULATING AIR

Separation chamber with positive and negative pressure design, internal circulating air operation, low energy consumption,and low noise

STEPPED CHANNEL

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.
