A new technology for producing nanometer calcium carbonate by new combined carbonization method

The theory foundation,technique characteristic and equipment structure of combined carbonization method are introduced.The comparison with other carbonization techniques is also described.The new combined carbonization technique has many advantages,such as simple equipment structure, convenient operation, easily achieved automatic control,and stable product quality.By controlling technique condition, a suit of equipment can be used to produce nano-level and minuteness-level calcium carbonate with multi-crystal types, different granularity and different property. In addition, it also has advantages,such as low consumption of energy under low temperature,less investment, continuous operation,high productive efficiency,large capacity with single carbonization tower, etc.This good technique is suitable for large-scale production.
