Embodiment Construction
[0025] The improved cement quick-setting agent preparation method is characterized in that: comprising steps:
[0026] The first step, mixed calcination of raw materials: take 28.8% of bauxite, 40.1% of limestone, 21% of soda ash, and 10.1% of raw coal for mixed calcination to make alumina clinker, and the calcination temperature is 900-1200°C , the duration of calcination is 60-80 minutes; adopt new clean furnace calcination technology, complete set of environmental protection facilities, mechanical automation production process, high efficiency, low consumption, high quality and stable product quality;
[0027] The second step, mixed grinding: get the above-mentioned fired alumina clinker and industrial coal cinder to carry out mixed grinding, wherein 42% of alumina clinker and 58% of industrial coal cinder are made into the prior art cement quick-setting agent, and the mixed grinding time It lasts for 20-40 minutes, adopts computer automatic batching, ¢1.83×7m ball mill con...
