A pneumatic conveying system moves bulk goods, by means of air pressure, through pipelines. Pneumatic conveyors require less maintenance, as compared to mechanical conveyors, due to fewer moving parts. The enclosed system prevents product loss and guards against contamination. Considerations for choosing a suitable pneumatic conveying system include the particle size of the product, length and complexity of the flow path, the desired flow rate, and sensitivity of the product to heat and mechanical shock. Pneumatic conveying systems are used in various industries to transport bulk powders, granules, and grains for processing and filling.
