In July 1985, a cement plant shaft kiln fire accident occurred in a factory in Hubei Province, resulting in one fatal accident and two serious fatal accidents. First, the accident after the shift workers at 16 o’clock, the normal kiln calcination. About 17 o’clock, raw material composition changes in the kiln (raw material KH is too high, aluminum high, low iron), kiln surface can not afford to fire, easy to Lianbian phenomenon. At this time to see the firework will be replaced by a continuous burning calcined kiln unloading a kiln (kiln burning). Each burning a kiln will be required to loosen the kiln side. About 21 o’clock Lianbian aggravated, stop feeding, is preparing to discharge, a small gap, the expected collapse, more than half an hour there was a big collapse of the material (about 1 meter drop), refining the edge of the furnace calm Side wall to the bordered area, accounting for about 1/3 of the kiln, and the kiln to take all the wind measures, and continue unloading. 21:40 to see the fireman, the operator four people in three points the entire kiln pry refining edge, 5 minutes after the fan found kiln material sealing black smoke, immediately issued to the kiln stop
