The High Output Food Grade Centrifugal Sifter Separator Airflow Screen is engineered for precision screening of powder materials ranging from 150-500 mesh. This industrial-grade equipment delivers exceptional screening efficiency with high throughput capacity, automated continuous operation, and superior dust control capabilities.

This centrifugal sifter achieves optimal screening results with various materials including 120-180 mesh light calcium, 300 mesh heavy calcium, 400 mesh active calcium, 300 mesh hawthorn powder, 320-500 mesh zinc powder, and 500 mesh iron oxide black. The system delivers approximately one ton of output per square meter of screen area per hour while maintaining screening accuracy exceeding 95% and air dust content below 10mg/m³.

Utilizing powder fluidity characteristics and lightweight properties, the airflow screen effectively diffuses powder particles into the air stream. Individual particles follow the airflow through the screen mesh, enabling precise powder separation across multiple industries including chemical, pharmaceutical, food processing, paper manufacturing, metallurgy, building materials, and rubber production.

The main machine features an air sifting mechanism with screen body supported by vibration isolation springs. The enclosed shell contains a vertical cylindrical screen with an internal circular wind wheel driven by a base-mounted motor. The upper section includes a hopper while the lower section houses discharge outlets and circulating air ducts. The motor connects flexibly to the main shaft with eccentric blocks on both ends, and the wind wheel upper end is supported by bearings.

The gas-solid separation dust removal system comprises an induced draft fan, settlement chamber, winch mechanism, and dust collection bags. The air screen connects to the separation system via two plastic corrugated hoses for efficient dust control.
