PROBLEM TO BE SOLVED: To provide a mixing system and method for a spraying material where the mixing of an admixture material is uniformly performed regardless of what the kind of the spraying material is, the pulsation of the spraying material press-feed system can be prevented, a satisfactory finished face can be obtained not depending on the skill of an operator, and the finished face is caked in a short time. SOLUTION: The mixing system comprises: a spraying material press-feed system Lm; an air feed system La; an admixture material feed system Lc; an injection nozzle 10 injecting a mixture of the spraying material, air, and the admixture material; an air addition apparatus 6 where the spraying material press-feed system Lm and the air feed system La are joined; and an admixture material addition apparatus 7 where the admixture material is added to a mixed flow of the spraying material and air. In the air addition apparatus 6, high pressure air forms a rotating flow spirally rotating in the flow passage of the air addition apparatus 6. COPYRIGHT: (C)2010,JPO&INPIT
