For the easy transportation of bulk solids such as powders, granules, pellets and irregular shaped particles, the use of Pneumatic conveying systems is often the easy and best solution. Supplied by professional companies such as www.aptech.uk.com/pneumatic-conveying-systems/ these state-of-the-art modern machines use air or other gas to propel the particles through a pipe. This clever and innovative system is a cost effective and efficient way to convey dry bulk material. Compared to mechanical systems, Pneumatic systems are much more reasonable to maintain. There are three main types of pneumatic conveying systems that can be used, Dilute Phase Pneumatic, Dense Phase and Semi-Dense Phase Pneumatic. The Dilute Phase is often used for non-fragile or abrasive materials, such as corn-starch or flour.
The Dense Phase Conveying system is more compatible with the transfer of friable or abrasive materials, such as sand, sugar, and carbon black prill. This is a slower style of transport system so that there is much less wear and tear on the products and the system itself. They can use a vacuum or gravity fed load conveyancing system with a bottom or top evacuation point. For products such as cement or fly ash then the Semi-Dense Pneumatic System is the optimum phase to use.
This medium speed transfer system is perfect for friable or aeratable abrasive materials and is the middle stage between the Dilute and Dense phases. This slow, gentler approach produces less wear and is suitable for all materials.
