Analysis of 15 Reasons for Blockage in Pneumatic Conveying Pipelines

Blockage of pneumatic conveying pipelines often occurs in the initial section below 150m from the outlet of the transmitter, such as the silo pump. This is because in the initial stage, the flow velocity is low and the concentration is high, making the flow pattern the most unstable. As the frictional resistance of compressed air consumes energy during the conveying process, the pressure inside the pneumatic conveying pipeline gradually decreases, the specific volume increases, the volume of compressed air expands, the flow rate increases, and it is less likely to clog. The later part of the pneumatic conveying pipeline will be automatically dredged even if it is blocked, because
