Abstract：A new method is reported for preparing ultra-fine CaCO3 power with average apparent particle size of about 20~30 nm by the new turbo-flow equipment with high shearing force. The suspension of Ca(OH)2 and mixture gases of CO2 and air were dispersed well in the turbo-flow equipment, and smashed in the high-shearing container under certain pressure. This method can control the shape and size of CaCO3 powder. In this technology, the equipment is simple with small volume and high efficiency, and the fluid flows smoothly and quantificationally. The technological parameters of the new method were also explored.
