The limestone must be calcined in such a way . 石灰石必须煅烧到这样地步。
It has to be crushed after firing and the aggregate therefore has sharp corners . 煅烧后需要进行破碎，因此骨料具有尖锐的棱角。
The activated carbon which can be rejuvenated by roasting procedures has improved the economy considerably . 已证实研制通过煅烧可再生的活性炭具有相当大的经济效益。
The carbonate from calcium carbonate, if not removed by calcining may cause foaming in the reactors . 碳酸钙中存在的碳酸根，如果不经煅烧除去，会在反应槽中引起泡沫生成。
Organic impurities are sometimes present to such an extent that the rock must be calcined to remove them . 有时候矿石中存在有机杂质甚多，以至必须将矿石进行煅烧以消除之。
In order to calcine calcium carbonate fines, the technique of high-temperature pelletization has successfully been used . 为了煅烧碳酸钙细粉，已经成功地应用了高温成球技术。
For this reason the distributor for the bed directly above the calcination stage should be made of heat-resistive material . 基此理由，直接位于煅烧段之上的床层分布板必须用耐热材料制成。
Phase transformation for calcined coal measures kaolinite 煅烧煤系高岭石的相转变
Calcination of small size limestone and dolomite 小颗粒石灰石和白云石的煅烧，
