中文摘要：
为有效利用小颗粒（-10mm）石灰石，采用静态煅烧的方法对粒径为0．5-10mm的石灰石进行煅烧，分析了煅烧温度、煅烧时间、石灰石粒径对煅烧产物活性的影响。结果表明煅烧温度和煅烧时间对石灰活性都有影响，煅烧温度低、时间短，石灰石煅烧不完全，石灰活性差；煅烧温度高、时间长，石灰石又容易过烧，石灰活性依然不高，且温度越高过烧出现的越快：石灰石在950℃煅烧60min得到的产物活性最佳；石灰石粒径对煅烧产物活性有影响．石灰活性并未随着石灰石粒径的增大而呈现单一趋势，大致是先增大后减小，实验中石灰活性最佳的石灰石粒径是2-3mm。
英文摘要：
In order to make effective use of the limestone with small particles （- 10 mm）, the method of static calcination was used to calcine the limestone sample of which the particle size was at 0.5-10 ram, and the influence of calcining temperature, calcining time, and particle size on the activity of calcined product was analyzed.Results showed that： calcining temperature and time could both affect the lime activity.With low calcining temperature and short time ,limestone can not be completely calclned,and the activity of lime was low;with high temperature and long time ,limestone would be easily over burnt,and activity of lime was still not high, and the higher the temperature was,the sooner over-burning appeared.The product of the best activity can be obtained when the limestone sample was calcined for 60 rain at 950 ℃.The particle size of limestone also had effect on calcined product＇s activity, and lime activity did not increase with particle size on a single increasing trend, but rather roughly first increased, then decreased.In this test the best lime activity appeared when particle size was at 2-3 mm.
