<P>PROBLEM TO BE SOLVED: To provide a production method for sodium chloride particulates (with an average particle size of 50 μm or less) excellent in caking prevention effect. <P>SOLUTION: The production method for sodium chloride having an average particle size of 50 μm or less has a step wherein a ferrocyanide solution is sprayed on and mixed with sodium chloride having an average particle size of 100-2,000 μm and the resultant mixture is pulverized. Otherwise, the production method for sodium chloride having an average particle size of 50 μm or less has a step wherein a ferrocyanide solution is sprayed on and mixed with sodium chloride having an average particle size of 100-2,000 μm and then sodium chloride having an average particle size of 100-2,000 μm is further added and mixed and a step for pulverizing the resultant mixture. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
