The invention relates to the field of chemical engineering, and particularly relates to a production method of active lime and a production system thereof. The production method of active lime comprises the following steps: mixing: mixing 8-20 parts of mountain flour and 1-2 parts of pulverized coal in parts by weight to form a mixed material; calcining: calcining the mixed material at 900-1200 DEG C, wherein the grain size of the mountain flour is less than 0.5cm. As the mountain flour and the pulverized coal are mixed, when the mixed material formed by the mountain flour and the pulverized coal is placed in a mixed material calcining device to be calcined, the pulverized coal which burns at high temperature releases heat to uniformly provide heat to decomposition of calcium carbonate in the mountain flour, so that calcium carbonate in the mountain flour is uniformly decomposed. The mountain flour and the pulverized coal are mixed according to a predetermined proportion. Heat released by burning the pulverized coal can provide enough heat to decompose calcium carbonate, so that decomposition of calcium carbonate in the mountain flour is accelerated, the time required by calcining is shortened, and the production efficiency of active lime is improved.
