Cov qauv crystalline ntawm calcite yog ib qho tseem ceeb ua rau nws tsis tsim nyog rau cov txiv qaub. Piv rau lwm cov limestones, calcite muaj qib siab dua ntawm crystallinity thiab nthuav tawm lub cubic crystal system. Qhov no ua rau calcite kuj nkig thiab nquag tawg thaum lub sij hawm calcination.
1.1 Qhov cuam tshuam ntawm crystallinity ntawm cov txheej txheem Calcination
High crystallinity ntawm calcite ua rau nws yooj yim rau kev puas tsuaj thaum lub sij hawm calcination. Lub hom phiaj ntawm calcination yog decompose cov calcium carbonate hauv limestone rau hauv calcium oxide, tab sis crystallinity siab ua rau cov kab nrib pleb hauv cov limestone hais, cuam tshuam rau tag nrho lub zog ntawm limestone.
1.2 Gas Flow Teeb meem tshwm sim los ntawm kev sib tsoo
Tom qab calcination, calcite tau yooj yim crushed, yog li cuam tshuam cov roj ntws hauv cov txiv qaub kiln. Qhov no ua rau muaj teeb meem hauv cov pa tso pa tawm, cuam tshuam rau cov thermodynamic thiab cov pa ntws sib npaug hauv cov txiv qaub kiln, thaum kawg cuam tshuam qhov zoo thiab kev ua haujlwm ntawm cov txiv qaub.
