These are also known as airslide conveyor systems or air gravity conveyors. These, however, have caused more complications, resulting in the invention of fluidised conveying systems.
To properly allow the transported material to flow, it was necessary to draw conveyor systems with a slope greater than the angle of repose of the material. On a permanent equilibrium the angle of repose of bulk materials naturally achieves a constant slope from the horizontal plane. This provides stability and less movement of the fabric while conveying. Pneuvay airslides, unlike those from other suppliers, install a perforated metal support sheet under the aeration cloth. Ultimately, it discharges cement into a tanker via a loading chute.Įxample of an airslide conveyor system Pneuvay airslides include perforated metal support sheet Typical example of airslide conveyor systemĪ typical airslide installation in a cement depot will convey cement (bulk powder) some distance from a silo discharge. Dust collection vents remove the spent air expended from the product during conveying.Air control valves used to adjust the amount of aeration air being used.
Weir plates, used to adjust the aeration bed depth.Fan or blower provides aeration air through the aeration cloth.Several point of how air works with the airslide conveyor system include: Inspection ports provide access to visually inspect inside the airslide section.Aeration cloth is generally woven permeable polyester.Turning boxes (pots) are used to divert flow from one direction to another.Section width and height of the aeration bed dictates the conveying rate.Some of the basic structural features of an air slide conveyor system include: Understanding how air slide conveyor systems work Knowing the basic airslide conveyor system features
They are, therefore, often a far better solution than screw conveyors, drag chains and belt conveyors. The food industry uses airslides for flour, and many powders in the chemical industry are ideally suited to airslides.Īirslides have no moving parts. They convey homogenous dry powder, including minerals, for use in cement, lime and fly ash. With some low pressure air, an aeration bed and a small incline (gravity), we can convey hundreds of tonnes of products over long distances.Īirslides are used extensively in many industries, including mining. When you are involved in the transfers of bulk powder and grains, understanding how airslide conveyor systems work will be of help as it is the 'best-fit' solution for many industrial circumstances.Īirslides provide some of the most efficient and practical methods of conveying bulk powder material.
