[PROBLEM] Provided is a transportation method for a water-absorbing resin powder substance, which is capable of suppressing property decrease of the water-absorbing resin powder substance while suppressing blocking phenomenon and is suitable for long distance transportation. [SOLUTION] The present invention is a transportation method for a water-absorbing resin powder substance during a production step by pneumatic transportation via a transportation pipeline. In this transportation method, two or more pneumatic transportation apparatuses (A, B, C) are provided in one transportation section, and these pneumatic transportation apparatuses (A, B, C) are connected by the transportation pipelines (P, P, P) in series.

Transportation method for water-absorbing resin powder substance

[Problem] To provide a pneumatic conveyance method for a water-absorbing resin powder substance, which is capable of suppressing property decrease of the water-absorbing resin powder substance, while suppressing obstruction phenomenon. [Solution] A conveyance method for a water-absorbing resin powder substance by pneumatic conveyance of the water-absorbing resin powder substance during a production step via a transportation pipeline, wherein a variation of a solid-gas ratio (R/R) exceeds 1 and is equal to or smaller than 7, provided that R(kg-resin/kg-air) stands for an initial solid-gas ratio at a start point of the transportation pipeline, and R(kg-resin/kg-air) stands for a terminal solid-gas ratio at a terminal point of the transportation pipeline is provided.
