PROBLEM TO BE SOLVED: To provide a pneumatic transport system of granular material capable of adjusting filling of a recovery tank and a control method of such system.SOLUTION: A pneumatic transport system of granular material includes: at least one loading device 10 of the granular material that communicates with a processing machine M for providing the granular material to the processing machine M and has a recovery tank 20; at least one conveying duct 100 of the granular material for fluidically connecting the recovery tank to at least one storage container T of the granular material; means 100, 35 for generating a flow of the granular material inside the conveying duct 100; and at least one sensor 51, 52 for detecting vibration induced by the granular material loaded inside the loading device. The at least one sensor 51, 52 is disposed at the loading device or in the vicinity thereof, and the at least one sensor 51, 52 generates a time signal of the vibration that is correlated to mass of the granular material loaded to the recovery tank or is correlated to volume of the tank filled by the granular material. |
