How it works?

The Wysetech Aero-Mechanical Conveyor is a highly versatile tubular system capable of handling an extremely wide range of dry bulk materials at up to 35 M³/Hr.


In the simplest form the Aero-Mechanical conveyor consists of two or more terminal sprockets and a wire rope and plastic disc assembly, joined to create a continuous loop around the sprockets. Each sprocket is positioned in a dust tight housing and is connected by stainless steel tubes in which the rope assembly runs. A direct worm drive is applied to one sprocket, causing the rope assembly to travel around the circuit


The plastic conveying discs are a loose fit in the tubes and travel at a relatively high linear speed of between 4-5m/s creating both air and material displacement thus fluidising the material by surrounding each particle with air resulting in high throughput with minimal damage and particle separation.


The principle of the circulating air column means that there is a ‘no loss’ situation when running the conveyor empty the conveyor re-circulates the same column of air at atmospheric pressure.


When material is introduced through the inlet it displaces air of equivalent volume and at the rate of introduction. It is necessary to allow this to leave the conveyor where a free passage is possible, hence the inlet /vent connection. Because the material is in a fluidised state in the inlet the air may be dust laden and therefore require dust suppression at this point.


At the discharge it is necessary to separate the material from the air and as with pneumatic conveying a centrifugal separation is required. This is done at the discharge end where the material moves to the outside of the housing and is discharged, air free, through the outlet and the air is taken down the return tube. Materials with bulk densities of 100 kg/M³ and 4000 kg/M³ have been conveyed by this principle.


At the outlet the material leaving the conveyor does require to be air replaced and a small quantity is drawn into the conveyor through the outlet. This is possible because the centrifugal action on the material forces it to the top side of the spout leaving an area at the bottom of the outlet where an inward flow of air can take place.
