摘要：By using a surface treatment agent on the surface of calcium carbonate, discussed the variation of the specific surface area of the calcium carbonate during the grinding process, determined the added amount and added time of the dispersing agent, and researched on the grinding effect. According to the changes about the specific surface area of the grinding calcium carbonate particles, compared with the different effects that added the uniform dispersant and added the corresponding needs dispersant, had the particle size relationship followed the change of the specific surface area, reach to the purpose that refine the particle size and get a narrower particle size distribution.
