The objective of this study is to obtain some basic information on the reduction of power consumption for the pneumatic conveying of granular materials in an inclined pipeline. To study experimentally the vibration effect on the pipeline under vibrating conditions, a pipeline consisting of a section of 50x50 mm and a length of 4100 mm was tilted up and down to some degree. The transport efficiency was improved by applying the vibration to the horizontal or downward-sloping pipeline and had its maximum value at a certain value of the acceleration ratio. For the upward-sloping pipeline, the vibration gave a contrary effect except for high-concentration transport such as the plug flow.
