Convey air flow diagram

Convey Air Flow (in blue)

The conveying air and the un-sifted material enters top center and begins to decelerate.

The conveying air seeks the path of least resistance, which is found through the air bypass screen positioned directly above the first sifting sieve.

The "filtered" low velocity conveying air travels down the side channels, re-entraining the sifted product, and conveying the product out of the sifter.


 

Material flow diagram

Material Flow (in green)

The un-sifted material (red & green)
enters from the top center and begins to decelerate.

Deflecting baffle prevents direct impact and properly loads the first screen.

Fine product (green) passes through screen and is discharged to side channels.

Tailings (red) flow across the screen and drop to a lower level.
