### What is an Air-Gravity Conveyor Vortex

Aug 20 2018 · An air-gravity conveyor is a device for moving a variety of light-weight fluidizable dry bulk powders. The conveyor consists of a rectangular chamber separated by an air-permeable porous media. The media is placed along a horizontal plane to separate two chambers within the conveyor An upper chamber to handle the material being conveyed and

The force allows the sand to be carried at a constant speed even if the changing mass on top of the conveyor belt is increasing. Because of the conservation of the momentum the rate of change in the momentum of the conveyor belt induced by the falling sand is also equal to the rate of change of the falling sand.

### Angle of reposeWikipedia

The angle of repose or critical angle of repose of a granular material is the steepest angle of descent or dip relative to the horizontal plane to which a material can be piled without slumping. At this angle the material on the slope face is on the verge of sliding. The angle of repose can range from 0° to 90°. The morphology of the material affects the angle of repose smooth rounded
