(57) The invention relates to the technical field of calcium carbonate preparation, in particular to a calcium carbonate suspension calcination preparation technology which comprises three supporting frames, a calcining furnace, a heating assembly, an air inlet set and a rotary material spraying set. According to the calcium carbonate suspension calcination preparation process designed by the invention, powdery limestone is uniformly scattered into the calcining furnace from top to bottom in a layered manner through the rotary material scattering group, so that the powdery limestone is quickly suspended in the calcining furnace and is heated by the heating assembly to be decomposed into lime powder; the calcium carbonate suspension calcination efficiency and the calcium carbonate suspension calcination uniformity are improved, the time of powdery limestone staying in the calcining furnace can be prolonged through rotation of the discharging barrel and the spraying pipeline, and the calcium carbonate suspension calcination efficiency is improved.
