To provide a dust splash prevention device in a powder scattering apparatus which controls the amount of water as much as possible and which is capable of effectively controlling the dust splash by spraying water to form a mist curtain with no gap, which is not fanned by normal wind.
The dust splash prevention device in the powder scattering apparatus has a structure that a ring type nozzle tube is fitted to the upper part of surrounding of a scattering mouth of a hopper to scatter a powdery solidifying material such as cement and the like from the scattering mouth at the under part and that a number of spray nozzles are fitted and arranged to the ring type nozzle tube towards the approximately lower part, and a cylindrical mist curtain is formed by spraying water without a gap on the surrounding of the scattering mouth from the spray nozzles so that the splash of dust dropping from the scattering mouth is prevented.
