METHOD OF PREPARING LIME COMPOSITION Russian patent published in 1999 - IPC

FIELD: inorganic materials technology. SUBSTANCE: method of preparing different- density lime compositions consisting in loading calcium oxide into limited space and mixing it with water is distinguished by that lump calcium oxide is fed into provision compartment at the angle of flowability and discharge zone is separated from ambient medium, magnetic inclusions are collected and put into collector, calcium oxide is transported to mechanism providing breaking calcium oxide and feeding it into chamber to be mixed with water, fine calcium oxide dust is caught and magnetized in all operation stages, mixed with carbon dioxide and added to lime solution, which is used to additionally break structure of lump material owing to discrete laminar-turbulent lime mortar stream that is passed through centrifuge together with granulated calcium oxide. When desired density of lime composition is reached, it is conveyed into process tanks and process is repeated. EFFECT: increased productivity to 5-8 minute one cycle time. 1 dwg
