MANUFACTURING METHOD OF BURNT LIME FROM LIMESTONE SLUDGE AND FINE LIMESTONE

摘要

The present invention is basically a moisture content below 32% , which is used in steel mills , magnesium oxide (MgO ) was dried in a rotary dryer component (rotary dryer) on the present invention to target the fine granules of raw limestone of 3-10% , and the limestone -containing sludge (sludge) and 15mm or less reduce the moisture to 10% or less after a specially designed rotary after the firing step at a temperature of 830 ~ 1150 in a kiln (rotary kiln) is cooled and milled to a method for producing the calcium oxide can be produced a minute with minute through a conventional exhaust gas burnt lime process .
