Production technology and device of high-quality calcium oxide
The present invention discloses a production technology and device of high-quality calcium oxide, and is intended to address the deficiencies that the calcium oxide produced after calcination of the existing limestone can be easily mixed with ash, underfiring and overburning are common in the calcining process, and the calcium oxide has lower quality. The process is as below: 1, selecting calcite as the raw material, cleaning and draining; 2, crushing the calcite and sieving calcite particles in similar size for standby; 3, sending the calcite raw material into a shuttle kiln for calcining; 4, taking calcium oxide out of the kiln, cooling calcium oxide to about 400 DEG C, and milling the calcium oxide at a temperature more than 200 DEG C; 5, after milling, sending the calcium oxide immediately into a sealed dry container for cooling, cooling to around 50 DEG C, and packaging immediately, wherein the time interval between taking calcium oxide out of the kiln and packaging is 30 min.
