The present invention provides a filler, rubber, paint pillar (filler), pigments, pharmaceuticals, cosmetics, toothpaste, food filtered when calcium carbonate solution to obtain after concentration in vacuum spraying / drying in a spray dryer additives such as non-toxic 1 ~ 0.1 ㎛ ㎚ range of particle size relates to an ultra-fine calcium carbonate which is available in a size to.
Herein it is determined yirueoseo the rapid cooling structure when then fired at a high temperature with high baektan pulverized limestone raw material, but do the carbonation reaction in a cooling tank of stainless steel SUS 303 material, is calcined at a high temperature limestone raw materials to be added to the cooled reaction vessel structure that has the technical idea of ​​obtaining a fine calcium carbonate by using a finely split characteristics but on cooling.
Herein pole by a manufacturing method for obtaining a fine calcium carbonate, limestone powder and the process after the firing in a mixture of baektan a high temperature, by performing the carbonation reaction in a cooling tank of stainless steel SUS 303 material to obtain the calcium carbonate aqueous suspension and, the process and the coated calcium carbonate aqueous suspension to fluorine silicon to obtain an antifouling function powdery calcium preparation of Poly ester filter ppaek on using a centrifuge 20 ㎛ ~ 0.1 ㎚ particle size using a having prepared in step, the calcium carbonate obtained in the above step grinding using a water stream classifier invention is directed to a method of manufacturing a calcium carbonate composed of the grain size by separation.
