Airflow Screening Machine

Production Problems It Solves

Loose agglomerates and oversize entering production

The rotor presents powder to the mesh so accepted material and retained particles follow separate outlets.

Gravity-fed powder forming a concentrated pile

The rotor distributes the powder against the cylindrical screen rather than depending on one small landing area.

Where It Fits in Your Plant

Flour and starch processing

Sift ingredients before blending or packing to separate oversized particles and loose lumps. Hard foreign objects can damage the screen and require upstream control.

Dry chemical fillers

Screen compatible calcium carbonate or similar powder ahead of packaging. Rotor action can affect fragile particles; this is a mesh sifter, not an air classifier that separates by aerodynamic behavior.

How the Airflow Screening Machine Works

Feed enters the housing and is distributed by a rotor. The movement presents powder to the cylindrical mesh; accepted material passes through while oversize is discharged separately. Rotor clearance and mesh support affect operation.

Selection Factors

• Screen cylinder: aperture and open area control passage, while support geometry must fit the rotor assembly.
• Rotor clearance: maintain the specified clearance between the moving elements and the screen.
• Feed condition: large hard pieces and abrasive contaminants can damage the internal screen.

Common Issues & Checks

• Increasing oversize discharge: inspect blocked mesh and excessive feed before changing the rotor setting.
• Metal contact or unusual noise: stop and isolate the machine before checking screen support, rotor clearance and wear.

Operating Precautions

Isolate the rotor before opening the screen housing.
