Air Gravity Separator
The Air Gravity Separator is a dry physical separation unit for classifying prepared granular material according to density, particle size and aerodynamic behavior. It combines controlled airflow, a rotating grading wheel, centrifugal classification, gravity settling, secondary air reclassification and staged discharge.

Equipment overview
A downstream air-classification stage after crushing, pulverizing and screening, not a vibrating gravity table.
The Air Gravity Separator is a dry physical separation unit for classifying prepared granular material according to density, particle size and aerodynamic behavior. It combines controlled airflow, a rotating grading wheel, centrifugal classification, gravity settling, secondary air reclassification and staged discharge. This is an air-classification and gravity system rather than a generic vibrating table. It is normally used after crushing, pulverizing and screening, when the feed is sufficiently liberated and has a useful difference in effective mass and aerodynamic response.

02 / Operating Principle
How the Air Gravity Separator Works
Prepared mixed material enters from the upper feed section and is distributed across the inclined separation deck. Controlled vibration, airflow and gravity work together to stratify the material by density so lighter and heavier fractions can follow different discharge paths.
02
Vibratory Conveying
The vibrating deck spreads the material into a controlled moving layer and carries it across the separation surface.
03
Air-Gravity Separation
Upward airflow and gravity act on the stratified material so particles with different densities separate into distinct trajectories.
04
Separate Discharge
Separated fractions leave through their respective discharge paths for collection or downstream processing.

Supplies upward process air beneath the deck to assist density-based separation.
06
Fraction collection hoppers
Collect separated material fractions from the lower discharge zones for downstream handling.
07
Air outlet interface

08
Machine housing and access doors
Encloses the separation system and provides service access for inspection, cleaning and maintenance.
05 / AIRFLOW SEPARATION ENGINEERING
Air Gravity Classification System
Engineering proof
Classification uses airflow, a rotating grading wheel, centrifugal force, gravity settling and secondary-air reclassification of fines attached to coarse particles.
Classification method
Airflow + centrifugal force + gravity
Fine-fraction path
Grading-wheel passage to cyclone / dust collector
Coarse-fraction path
Wall descent and lower outlet
Secondary air
Reclassifies fines attached to coarse particles
Process water
Dry classification; no process water
Configuration note
Moisture, particle-size distribution, shape, surface dust and degree of liberation can change the cut point. Sample testing is recommended before final selection.

09 / Equipment FAQ
Common selection questions
Is this a vibrating gravity table?
No. The described system is an air-classification unit using induced airflow, a rotating grading wheel, centrifugal force and gravity. A vibrating deck should not be assumed unless it is included in the determined configuration.
What feed condition is required?
Use dry, free-flowing and reasonably liberated particles with a controlled size distribution. Wet, oversized or strongly agglomerated feed can reduce classification stability.
Can the fine fraction go to an electrostatic separator?
It can, when the material is dry and within the electrostatic separator's accepted size range. The interface and feed conditioning should be determined as one process design.
Are capacity and separation results guaranteed?
No. Capacity, cut point, purity and recovery depend on material properties, airflow, wheel speed, dust loading and line configuration. They should be established from representative tests and written into the final equipment quotation.
What information is needed for a quotation?
Provide representative samples or photos, composition, particle-size distribution, moisture, required capacity, target products, installation country, site utilities and available layout.
