The Free Power of Gravity
FLSmidth’s Airslide™ Air Gravity Conveying
System uses the forces of gravity to do most of
the work without any moving parts. Material
is fluidized through a porous media with low
pressure air. Material flow is achieved by
sloping the Airslide conveyor to match the
fluidized angle of repose of the powdered
material. At the correct slope, fluidized
materials flow with the consistency of a liquid.
Airslide Air Gravity systems provide high-
capacity material handling while offering
many economical and environmental
advantages. Energy requirements are minimal
because only a small volume of air at a low
pressure is required to move material. Since
the system is installed overhead, valuable
floor space and added headroom are
available for other purposes. By eliminating
the need for massive support members,
it permits a flexibility of plant design not
available with straight-line conveyors.The Airslide conveyor is dust tight.
As a result, the system is extremely
friendly to the environment.
Noise level is extremely low in the area
surrounding the Airslide conveyor
as the system’s air supply is the only
moving part to generate noise, and
it is generally located in a remotely
insulated area to further reduce noise.
Maintenance of the Airslide conveyor is very
simple because there are no moving parts
other than the air supply equipment, which
also contributes to increased plant safety.
Airslide conveyors require no lubrication.

Gathering under baghouses / precipitators•
Feed to process•
Feed to other conveyors•
Loadout from bulk silos to•
trucks, railcars or barges
In-plant conveying•
Storage silo / bin withdrawal•
The Principle of Fluidization:Driving low-pressure, low-velocity air through and between particles of a dry bulk material,
changing its behavior characteristics and making it flow more like a liquid than a solid
All fly ash has a natural angle of repose,often in excess of 45 degrees.

Airslide System Recirculation: SO2 Mitigation - Circulating Dry Scrubbers
For pebble lime and limestone (unloading, conveying and injection)
Most new plants will be designed with some form of SO2 mitigation in the form of wet or dry scrubbers.
Such scrubbers are also being
retrofitted on existing plants for (a)environmental compliance and (b) to
allow for the switch to less expensive
high sulphur coals.
Standard FLSmidth Airslide systems
can be employed for all of these
lime-based handling applications. Specialized “circulating dry scrubbers (CDS)” all employ FLSmidth Airslide
technology.
