Yanfeng calcined dolomite two-step preparation of calcium magnesium sand

摘要

In this paper the influence of beforehand condition and sinter degree to capability of sintered dolomite has been investigated by means of measure actived degree and capability of high temperature sintered and property of resist hydrate of different material granularity after different beforehand sinter degree. Ascertain the activate of dolomite is the best when the beforedhand sinter degree is 850°C. The beforehand sinter time is 3 hours. And the sinter degree is 1650°C. The material bulk-density reach 3.2 g/cm~3 and the cability of resist hydrate reach 2.1%.when dolomite are preparted on this condition.
