摘　　要：用节能型立窑煅烧30-80mm的小块石灰石,月产生石灰8 000t,石灰CaO含量平均91%,活性度300mL,生过烧率≤8%。获得了可观的经济效益,减少了资源浪费,也降低了生产成本。The energy-saving shaft kiln calcines the limestone with small grain size ranging from 30mm to 80mm.Its monthly production of lime is 8 000t.The average calcium oxide content in lime is 91%;the reactivity of produced lime is 300mL;both over-burnt and under-burnt rates are ≤8%.Considerable economic benefit is obtained,and the waste of resource and production cost are reduced.
