Zusammenfassung:PROBLEM TO BE SOLVED: To prevent deformed slurry or lumps in the periphery of the bottom of a tank from flowing into a CPM device, by vertically transferring a supply pipe by a supply pipe transfer means corresponding to the vertical movement of the slurry level in the tank so that the suction inlet is always positioned at a specified depth from the slurry level. SOLUTION: A transfer means of a supply pipe is fixed to the lower end of a supply pipe 113 and formed of a floating body 120 always positioned at the slurry level owing to the own buoyant force. The suction inlet 113a of the supply pipe 113 is arranged at least at a lower level than the bottom face of the floating body 120 to be always submerged in the upper layer of the slurry by a preset depth (a). The floating body 120 is constituted of a floating bag having a large buoyant force or the like. The supply pipe 113 vertically transfers in accordance with the increase or decrease of the slurry in the tank 111 or the vertical movement of the slurry level. The suction inlet 113a of the supply pipe 113 is always kept so as to be submerged in the upper layer of the slurry at a preset depth (a) regardless of the increase or decrease of the slurry.
