Pneumatic conveying provides an effective, enclosed transport system for manufacturing, handling and processing applications where small particles are required. PRECISION FLOW CONTROL FOR EFFICIENT, ACCURATE PNEUMATIC CONVEYING SYSTEMS neumatic conveying provides an effective, enclosed transport system for manufacturing, handling and processing applications where small particles, grains, pellets and powders are required. P These flexible transport systems offer a number of handling advantages over more conventional mechanical systems as well as being able to deliver precision flow control. Modern environmental control standards can be difficult t o maintain when working with powders and small 82 PECM Issue 31 particles as part of a manufacturing process. One of the most effective solutions is to use pneumatic conveying, which also offers a number of benefits when compared to more traditional methods. Reduced maintenance, due to the lack of moving parts Improved operational environment with no dust thanks to the fully enclosed design System flexibility that allows for multiple drop points and considerable transfer distances. The possibility to carry out physical mixing or chemical reactions during the conveying process. The ability to convey air-sensitive materials using an inert gas, such as nitrogen, to prevent oxidation. Pneumatic conveying is used by a wide range of industries including food and beverage, pharmaceutical, chemical and power generation. The main challenges for those operating a pneumatic conveying system are keeping the consistency of the product and maintaining a precise controllable flow of the product. However, the modern manufacturing enterprise must also operate as efficiently as possible and this means reducing costs
