Using a series of pipes that have gas or air pumped through them to effectively move products, such as granules or powders, from one location to another, this seemingly complex system of Pneumatic conveying is actually quite a simple process. The pipes are vacuum sealed and airtight so that the materials inside them are moved quickly through the enclosed space. Possibly the main applications for this process are, metal powder transporters, burner feeders, recycling or any other application needed to transfer granules, powders or flakes, quickly and efficiently. The main advantages of this type of system are, it has fewer moving parts, so requires less maintenance and is safer to use, presenting less danger to operators. Classified as either pressure delivery or vacuum delivery, products can also be separated into dilute or dense phase for transport.
In pressure conveying the pick-up of materials is completed at one site and then delivery is to multiple sites. In vacuum conveying the pick-up of materials is at several points but delivery is at only one site. Utilising pressure differentials and the stream of gas, this system is both a cost-effective and quick method to move masses of powder or granular materials, with very little loss of products.
Dry products such as sugar, sand, wheat, and concrete powder are probably the most common items to be transported via the Pneumatic Conveying System. This is a very adaptable method and the pipes can be directed around existing machinery.
