K\u0131rma, refrakter end\u00fcstrisinde \u00f6nemli bir s\u00fcre\u00e7tir. Fabrikaya teslim edilen hammaddeler, \u00e7o\u011fu 25 mm’nin \u00fczerinde bloklar olmak \u00fczere, tozdan yakla\u015f\u0131k 350 mm’ye kadar de\u011fi\u015fmektedir. Fabrikadaki k\u0131rma i\u015flemi ve hammadde se\u00e7imi, \u00fcr\u00fcn\u00fcn \u00f6zelliklerine do\u011frudan etki eden y\u00fcksek kaliteli \u00fcr\u00fcnlerin \u00fcretilmesinin anahtar\u0131d\u0131r. Ayr\u0131ca maliyet muhasebesi a\u00e7\u0131s\u0131ndan k\u0131rma ve k\u0131rma ekipmanlar\u0131n\u0131n t\u00fcketti\u011fi g\u00fc\u00e7 b\u00fcy\u00fck bir orana sahiptir. Enerjiden tasarruf etmek ve maliyetleri d\u00fc\u015f\u00fcrmek i\u00e7in k\u0131rma i\u015flemine dikkat edilmelidir.<\/p>\n
K\u0131rma i\u015fleminin \u00f6z\u00fc, a\u015fa\u011f\u0131daki fakt\u00f6rlerle ilgilidir, yani malzemenin y\u00fczey par\u00e7ac\u0131klar\u0131n\u0131n y\u00fczey geriliminin a\u015f\u0131lmas\u0131 ve malzemenin i\u00e7 par\u00e7ac\u0131klar\u0131 aras\u0131ndaki Coulomb \u00e7ekiminin \u00fcstesinden gelinmesidir. Silikat fiziksel ve kimyasal dispersiyon sisteminin temel konseptinden yola \u00e7\u0131karak, ezilmi\u015f malzemenin par\u00e7ac\u0131klar\u0131n\u0131n ilk ezildiklerinde hala \u00e7ok b\u00fcy\u00fck oldu\u011funu, dolay\u0131s\u0131yla par\u00e7ac\u0131klar\u0131n y\u00fczey ve y\u00fczey enerjilerinin k\u00fc\u00e7\u00fck oldu\u011funu g\u00f6rmek zor de\u011fildir. , Malzemeyi 1\u03bcm (mikron) alt\u0131nda ezmek zordur, par\u00e7ac\u0131k ne kadar k\u00fc\u00e7\u00fckse, y\u00fczey enerjisi o kadar y\u00fcksektir, bu nedenle ince k\u0131rma s\u0131ras\u0131nda y\u00fczey enerjisinin \u00fcstesinden gelmek i\u00e7in daha fazla enerji t\u00fcketilecektir. Ayr\u0131ca ince \u00f6\u011f\u00fctme s\u0131ras\u0131nda par\u00e7ac\u0131klar\u0131n \u0131s\u0131l hareketinin h\u0131zlanmas\u0131 nedeniyle par\u00e7ac\u0131klar\u0131n \u00e7arp\u0131\u015fma olas\u0131l\u0131\u011f\u0131 artar, birle\u015fme ve p\u0131ht\u0131la\u015fma da meydana gelebilir. Bu nedenle k\u0131rma i\u015fleminin do\u011fru organize edilmesi, nihai \u00fcr\u00fcn\u00fcn da\u011f\u0131lma derecesine g\u00f6re k\u0131rma y\u00f6ntemi ve ekipmanlar\u0131n\u0131n se\u00e7ilmesi gerekmektedir.<\/p>\n
K\u0131rma amac\u0131:
\n(1) K\u0131rma, zenginle\u015ftirme s\u00fcrecinde \u00f6nemli bir i\u015flem halkas\u0131d\u0131r. \u0130ki veya daha fazla farkl\u0131 mineralin bir araya geldi\u011fi ham cevherden ayn\u0131 bile\u015fenin taneciklerini ay\u0131r\u0131p zenginle\u015ftirirken, t\u00fcre g\u00f6re ay\u0131rt etmek i\u00e7in \u00f6nce ham cevherin ezilmesi gerekir.
\n(2) \u00c7e\u015fitli fazlar aras\u0131ndaki etkile\u015fimi desteklemek veya kat\u0131 par\u00e7ac\u0131klar\u0131 s\u0131v\u0131ya e\u015fit \u015fekilde da\u011f\u0131tmak i\u00e7in, \u00f6rne\u011fin \u00e7amur haz\u0131rlay\u0131n.
\n(3) Proses gereksinimlerine g\u00f6re \u00e7e\u015fitli par\u00e7ac\u0131k boyutlar\u0131 haz\u0131rlay\u0131n. Kafes kusurlar\u0131n\u0131 ve malzemenin spesifik y\u00fczeyini art\u0131r\u0131n, fiziksel ve kimyasal reaksiyonlar\u0131 h\u0131zland\u0131r\u0131n ve sinterlemeyi te\u015fvik edin.
\nEzme y\u00f6ntemleri kabaca \u015fu d\u00f6rt t\u00fcre ayr\u0131labilir: ekstr\u00fczyon, darbe, \u00f6\u011f\u00fctme ve b\u00f6lme. \u00c7e\u015fitli k\u0131rma makinelerinin i\u015flevi, yukar\u0131daki y\u00f6ntemlerin bir kombinasyonudur.<\/p>\n
K\u0131rma, kuru k\u0131rma ve ya\u015f k\u0131rma olarak ikiye ayr\u0131l\u0131r. Ya\u015f k\u0131rma daha \u00e7ok seramik veya \u00f6zel refrakter malzemelerin \u00fcretiminde kullan\u0131lmaktad\u0131r. Kuru k\u0131rma ile kar\u015f\u0131la\u015ft\u0131r\u0131ld\u0131\u011f\u0131nda, a\u015fa\u011f\u0131daki avantajlara sahiptir:
\n(1) Ezme oran\u0131 b\u00fcy\u00fckt\u00fcr ve ezilmi\u015f malzemenin par\u00e7ac\u0131k boyutu k\u00fc\u00e7\u00fckt\u00fcr;
\n(2) Ezme verimlili\u011fi y\u00fcksektir ve kuru k\u0131rma s\u0131ras\u0131nda “toz duvar\u0131” olgusunun olu\u015fmas\u0131 kolay de\u011fildir (ancak ezilmi\u015f \u00fcr\u00fcn\u00fcn par\u00e7ac\u0131k boyutu 0,01 mm’den az oldu\u011funda, toz agregasyonu da meydana gelir);
\n(3) Ekipman ve ta\u015flama g\u00f6vdesinin s\u00fcrt\u00fcnme kayb\u0131 k\u00fc\u00e7\u00fckt\u00fcr;
\n(4) Uygar \u00fcretim ve proses otomasyonu i\u00e7in elveri\u015fli olan iyi toz \u00f6nleme.<\/p>\n
