METHOD OF LIME-STONE PROCESSING Russian patent published in 1996 - IPC

FIELD: lime-stone burning field, method is used in production of building materials and carbon dioxide. SUBSTANCE: lime-stone comminution is made till fraction of 1 mm is no less than 90 %. Lime-stone clearing is exercised in gas flow of smoke gasses with separation of up to 90 % burned lime in cyclone. After cyclone smoke gasses are subjected to wet clearing with separation of lime milk and carbon dioxide. Gas flow is produced by fuel burning in oxidation medium made of mixture of after separation produced carbon dioxide and oxygen. EFFECT: increased effectiveness of lime-stone processing. 2 cl, 1 dwg
