Aero Mechanical Conveyors


Our Aeroflow aero mechanical conveyor has a tubular design where a cable assembly, with evenly spaced polyurethane discs, move at high speed.  The cable assembly runs in specially designed sprockets at each corner and each end of the conveyor.  The action of the cable assembly traveling at high speed creates an air stream running at the same velocity.  As the material is fed into the airstream, it is fluidized and conveyed to the outlet where it is centrifugally ejected.

Proven Design:  As the leading provider of aero mechanical conveyors, Spiroflow has provided these conveying systems operating throughout the world.

Operates at any angle:  One of the most significant features of the aero mechanical conveyor is its ability to convey materials between 0° and 90° without any loss of capacity.

Goes around corners:  Aero mechanical conveyors can be supplied in a variety of configurations enabling them to transfer materials vertically and horizontally within the same unit.  These conveyors can also be linked together allowing one aero mechanical conveyor to feed another.

Easy to clean:  Because of the total transfer capability of aero mechanical conveyors cleaning is not necessary for most applications.  To avoid cross-contamination of product it is often sufficient to simply purge the conveyor with a sacrificial quantity of material.  Safety interlocked cleaning/inspection hatches can be fitted to both the conveying tubes and the sprocket housings.  Additionally, aero mechanical conveyors fitted with wash gates and drains can be washed through with water or another cleaning fluid.

Totally enclosed for total containment and dust free conveying:  All conveying takes place in a totally sealed tubular system which ensures the dust-free transfer of even the finest powders.

No dust collection system:  With an aero mechanical conveyor no additional air is added to convey material so there is no excess air at the outlet to filter for dust.  Any material that is not ejected at the outlet is simply carried around the enclosed system until it is.

Low power consumption:  Pound for pound conveyed, aero mechanical conveyors are one of the most efficient conveyors available.  Users benefit by their minimal power requirements and associated energy savings.

Total transfer:  It's simple. What is fed into the conveyor at the inlet is discharged at the outlet.  This makes the aero mechanical conveyor ideal for transferring pre-weighed batches of bulk and/or minor ingredients.

Gentle conveying action:  Materials are suspended in a cushion of air within the conveying tube as it is displaced by the discs traveling at speed.  This makes for a gentle conveying action that minimizes damage to fragile finished products.

Multiple inlets and outlets:  The concept lends itself to multiple outlets so that one conveyor can deliver material to a series of silos for example.  Multiple inlets are possible as long as only one is operational at a time.

Mobile:  Spiroflow aero mechanical conveyors can readily be mounted on a wheeled frame complete with controls and a power connection.  This makes it possible to use one conveyor to serve several processes or to remove it to a remote wash-down area for cleaning.  Optional height adjustment on mobile units is also available when they have to pass under low doorways or when they must discharge at differing heights.

Conveys difficult materials:  Virtually all materials can be conveyed in an aero mechanical conveyor ranging from the finest of powders to granules, pellets, flakes, and flocks.  We have been particularly successful with titanium dioxide which is a notoriously difficult material to convey.

Maintains mixtures:  Given that product is metered into aero mechanical conveyors at a controlled rate, there are almost identical amounts in each pocket between the discs.  The conveying action itself is gentle and therefore tends not to disturb mixtures.  The combination of these two factors means that the integrity of mixtures is maintained during conveying.

High throughput:  Aero mechanical conveyors can operate at speeds up to 36 ft3/min or 2,160 ft3/hour (1 m3/min or 61 m3/hr) with many products such as flour. They are capable of conveying rates in excess of 160,000 lb/hr (72,600 kg/hr) but this rate will vary according to the bulk density of the product.
