2. The rotary kiln is open-type calcination process. Its structure is very simple. The quality of ﬁnal lime is stable and with low rate of light-burnt and over-burnt. The rotary kiln can make the high quality lime with higher activity for steel making industry. Under the same conditions, the activity of lime produced by rotary kiln is higher than that of gas-ﬁred vertical kiln, with an average 30mL higher, and the activity is normally 340~380mL, even up to 400mL.,football all games today

The construction of the rotary kiln production line can not only make full use of high-quality limestone mine resources, but also can meet the sustainable development policy of the lime industry.
