PROBLEM TO BE SOLVED: To realize a usage of a pump in which a countermeasure for a solid component of a slurry is not applied in a slurry feed device. SOLUTION: A fluid becoming a mother liquid of the slurry is fed to a pipe 18 by a reciprocating pump 12. A throwing mechanism 20 for the slurry is provided on the pipe 18. The throwing mechanism 20 is rotatably provided and has a cylinder 22 having four chambers 30 arranged on the same circumference making this rotation shaft as a center. The cylinder 22 is disposed such that one chamber 30 becomes a coaxial arrangement with the pipe 18. A hopper 26 for filling a powder 24 to the chambers other than this chamber is arranged. The powder 24 filled in the chamber 30 from the hopper 26 is fed to the pipe 18 by the rotation of the cylinder 22 and is thrown and mixed to the mother liquid fed from the reciprocating pump 18. Thereby, a slurry is formed and fed to a downstream. COPYRIGHT: (C)2004,JPO
