Pneumatic conveying systems offer companies an effective means by which their products can be moved without the risk of product damage, spilling or other hazards. In agricultural settings, pneumatic conveying systems can be used for the safe, effective and sanitary transportation of harvested material like grain and corn. In oil refinement and other petrochemical-related processes, hazardous materials can sometimes be moved through pneumatic equipment more safely than they can by other means. Bank drive-throughs often make use of pneumatic conveyor systems; a combination of compressors and vacuum pumps move containers back and forth between tellers and customers, which makes transactions quick and easy.
Pneumatic conveying systems require several components in order to function, and these components vary depending on each system's configuration. There are two main pneumatic conveyor configurations: dilute phase and dense phase. Dilute phase conveyors force a stream or air or use a high-power vacuum to suspend objects in the air and move them through a channel. Dilute phase conveyors are often used for the transportation of fine powders and other collections of very small objects. Dense phase conveyors use air streams or high-power vacuums to move objects as well, but they are not diluted by air or suspended in the channel. This method is used for the transportation of larger, more cohesive objects. In order to generate the air pressures necessary to move solid objects, pneumatic conveying systems must be equipped with powerful air compressors and high-power vacuum generating equipment. Their channels must also be air-tight to ensure the sustainability of air pressure. Because pneumatic conveyors use air pressures instead of mechanical force, they can be used to move products between floors, around awkward corners and in other ways that would be impossible for mechanical conveyors. This is true of both dilute and dense phase conveyors.
