It is an object of the present invention to provide a method and apparatus for spraying an amorphous refractory material which is kneaded by adding water during conveyance of a powder material, which has a low moisture content, a high kneading effect, and an excellent workability. In order to solve this problem, the primary water dispenser 7 is provided in the conveying hose 5 from the material feeder 1 to the tip spray nozzle 4, and in front of the tip spray nozzle 4 at the tip spray nozzle side. Tea drinking machine 8 is provided. The primary water dispenser 7 is provided at intervals upstream of the secondary water dispenser 8, and from the primary water dispenser 10 to 50% by mass of the total construction water, more preferably 15 to 40% by mass By adding water as atomized water having an average particle diameter of 100 µm or less, the spraying material in conveyance is uniformly wet so as not to form a slurry, and the remaining water required for construction is spray-poured together with the compressed air from the secondary water dispenser. |
