Seramik tesisleri, mineral i\u015fleyicileri ve \u00f6zel kimyasal operasyonlar i\u00e7in yirmi y\u0131l\u0131 a\u015fk\u0131n s\u00fcredir \u00f6\u011f\u00fctme medyas\u0131 belirledikten sonra, en ucuz medyan\u0131n nadiren en ekonomik oldu\u011funu \u00f6\u011frendim.

Bu bilyalar, tipik olarak 92 % ila 99 % Al\u2082O\u2083 aral\u0131\u011f\u0131nda al\u00fcminyum oksitten yap\u0131l\u0131r. Al\u00fcmina i\u00e7eri\u011fi ne kadar y\u00fcksek olursa, a\u015f\u0131nma direnci o kadar iyi olur ve safs\u0131zl\u0131k riski o kadar d\u00fc\u015f\u00fck olur. \u00dcretim, az miktarda sinterleme yard\u0131mc\u0131lar\u0131 ile kar\u0131\u015ft\u0131r\u0131lan dikkatlice \u00f6\u011f\u00fct\u00fclm\u00fc\u015f al\u00fcmina tozu ile ba\u015flar. Toz daha sonra haddeleme veya izostatik presleme yoluyla k\u00fcreler haline getirilir, kurutulur ve 1500 \u00b0C'nin \u00e7ok \u00fczerindeki s\u0131cakl\u0131klarda pi\u015firilir. Sinterleme s\u0131ras\u0131nda partik\u00fcller \u00e7ok d\u00fc\u015f\u00fck g\u00f6zeneklili\u011fe sahip yo\u011fun, ince taneli bir yap\u0131ya ba\u011flan\u0131r.

Al\u00fcmina bilyelerin Mohs sertli\u011fi 9 civar\u0131ndad\u0131r ve bu da kuvars, feldispat, zirkon ve bir\u00e7ok cevheri etkili bir \u015fekilde \u00f6\u011f\u00fctmek i\u00e7in yeterince y\u00fcksektir.

Islak \u00f6\u011f\u00fctmede a\u015f\u0131nma oranlar\u0131 tipik olarak \u00e7ok d\u00fc\u015f\u00fckt\u00fcr - normal ko\u015fullar alt\u0131nda genellikle saatte 0,02 %'nin alt\u0131ndad\u0131r - bu da ortam y\u00fck\u00fcn\u00fcn daha uzun s\u00fcre dayanmas\u0131 ve de\u011firmen astar\u0131n\u0131n daha az agresif a\u015f\u0131nma g\u00f6rmesi anlam\u0131na gelir. Malzeme kimyasal olarak inert oldu\u011fu i\u00e7in \u00e7o\u011fu asit, alkali veya organik bile\u015fikle reaksiyona girmez ve neredeyse hi\u00e7 demir veya di\u011fer metalik kirlilik olu\u015fturmaz. Bu son nokta, az miktarda demirin bile rengi de\u011fi\u015ftirebilece\u011fi veya pi\u015fmi\u015f \u00fcr\u00fcnde kusurlara neden olabilece\u011fi seramik g\u00f6vdeleri veya s\u0131rlar\u0131 ta\u015flarken kritik \u00f6neme sahiptir.<\/p>\n
Pratik fark\u0131 bir\u00e7ok kez g\u00f6rd\u00fcm. Bir s\u0131r tesisinde, \u00e7akmakta\u015f\u0131ndan 95 % al\u00fcmina bilyeye ge\u00e7i\u015f, parti tutarl\u0131l\u0131\u011f\u0131n\u0131 art\u0131r\u0131rken \u00f6\u011f\u00fctme s\u00fcresini yakla\u015f\u0131k 25 % azaltt\u0131. \u00c7ak\u0131l ta\u015flar\u0131 d\u00fczensiz bir \u015fekilde a\u015f\u0131n\u0131yor ve zaman zaman yontularak elenmesi gereken kaba partik\u00fcller b\u0131rak\u0131yordu. Al\u00fcmina bilyeler daha uzun s\u00fcre yuvarlak kald\u0131 ve daha s\u0131k\u0131 bir partik\u00fcl boyutu da\u011f\u0131l\u0131m\u0131 \u00fcretti. Silika kumu i\u015fleyen bir mineral \u00f6\u011f\u00fctme devresinde, ayn\u0131 ortam demir toplanmas\u0131n\u0131 tespit edilebilir s\u0131n\u0131rlar\u0131n alt\u0131na indirdi ve bu da a\u015fa\u011f\u0131 y\u00f6nde ekstra bir manyetik ay\u0131rma ad\u0131m\u0131n\u0131 ortadan kald\u0131rd\u0131.

Elbette al\u00fcmina bilyeler her uygulama i\u00e7in do\u011fru cevap de\u011fildir. Kilogram ba\u015f\u0131na \u00e7elik bilyelerden veya temel seramik ortamlardan daha pahal\u0131ya mal olurlar, bu nedenle gerek\u00e7e genellikle daha az kontaminasyon, daha uzun ortam \u00f6mr\u00fc veya ton \u00fcr\u00fcn ba\u015f\u0131na daha d\u00fc\u015f\u00fck enerji kullan\u0131m\u0131d\u0131r. A\u015f\u0131r\u0131 sert cevherlerin \u00e7ok y\u00fcksek darbeli kuru \u00f6\u011f\u00fct\u00fclmesinde, daha y\u00fcksek yo\u011funluk ve tokluk nedeniyle zirkonya veya \u00e7elik bilyalar tercih edilebilir. De\u011firmen uzun s\u00fcre bo\u015f \u00e7al\u0131\u015ft\u0131r\u0131l\u0131rsa veya \u015farj\u0131n i\u00e7ine yabanc\u0131 metal nesneler girerse al\u00fcmina bilya da tala\u015flanabilir veya k\u0131r\u0131labilir, bu nedenle iyi temizlik ve uygun de\u011firmen y\u00fckleme prosed\u00fcrleri \u00f6nemlidir.<\/p>\n
Se\u00e7im ve kullan\u0131m detaylar\u0131 g\u00f6zle g\u00f6r\u00fcl\u00fcr bir fark yarat\u0131r. Yayg\u0131n bir hata, t\u00fcm \u015farj i\u00e7in tek bir bilye boyutu kullanmakt\u0131r. En verimli kurulumlar kademeli bir \u015farj kullan\u0131r - ilk par\u00e7alama i\u00e7in daha b\u00fcy\u00fck bilyeler ve ince \u00f6\u011f\u00fctme i\u00e7in giderek daha k\u00fc\u00e7\u00fck olanlar. Islak de\u011firmenlerde bilya-malzeme oran\u0131 ve bulama\u00e7 viskozitesi de izlenmelidir; a\u015f\u0131r\u0131 viskoz kaymalar bilyalar\u0131 yast\u0131klayabilir ve \u00f6\u011f\u00fctme verimlili\u011fini azaltabilir. Bilye a\u015f\u0131nmas\u0131n\u0131n d\u00fczenli olarak kontrol edilmesi ve ara s\u0131ra yap\u0131lan takviyeler \u015farj\u0131n en iyi \u015fekilde \u00e7al\u0131\u015fmas\u0131n\u0131 sa\u011flar. Genellikle sahada en \u00e7ok kullan\u0131lan boyutlardan k\u00fc\u00e7\u00fck bir stok bulundurman\u0131z\u0131 \u00f6neririm, b\u00f6ylece de\u011firmenler teslimat beklerken t\u00fckenmi\u015f veya k\u00f6t\u00fc derecelendirilmi\u015f bir \u015farjla \u00e7al\u0131\u015fmak zorunda kalmaz.<\/p>\n
Kullan\u0131m\u0131 basittir ancak dikkatle yap\u0131lmal\u0131d\u0131r. Yeni bilyalar y\u00fcklenmeden \u00f6nce \u00e7atlak veya tala\u015f a\u00e7\u0131s\u0131ndan incelenmelidir. Bir de\u011firmeni doldururken, t\u00fcm \u015farj\u0131 bir kerede bo\u015faltmak yerine de\u011firmen yava\u015f\u00e7a d\u00f6nerken bunlar\u0131 kademeli olarak eklemek en iyisidir. Bir kampanyadan sonra, a\u015f\u0131nm\u0131\u015f bilyalar genellikle elenebilir ve biraz daha k\u00fc\u00e7\u00fck medyay\u0131 tolere eden farkl\u0131 bir de\u011firmende yeniden kullan\u0131labilir.<\/p>\n
Daha geni\u015f bir perspektiften bak\u0131ld\u0131\u011f\u0131nda, al\u00fcmina \u00f6\u011f\u00fctme bilyeleri enerji t\u00fcketimini ve at\u0131klar\u0131 azaltmaya y\u00f6nelik mevcut bask\u0131lara iyi uyum sa\u011flar. Yava\u015f a\u015f\u0131nd\u0131klar\u0131 i\u00e7in, at\u0131lmas\u0131 veya geri d\u00f6n\u00fc\u015ft\u00fcr\u00fclmesi gereken kullan\u0131lm\u0131\u015f medya hacmi bir\u00e7ok alternatife g\u00f6re daha d\u00fc\u015f\u00fckt\u00fcr. Tutarl\u0131 performanslar\u0131 ayn\u0131 zamanda tesislerin sabit verimi korumas\u0131na yard\u0131mc\u0131 olur, bu da dolayl\u0131 olarak ba\u015flatma ve kapatma d\u00f6ng\u00fcleri s\u0131ras\u0131nda bo\u015fa harcanan enerjiyi azalt\u0131r.<\/p>\n
Sonu\u00e7 olarak, al\u00fcmina \u00f6\u011f\u00fctme bilyeleri pop\u00fclerli\u011fini koruyor \u00e7\u00fcnk\u00fc i\u015fletme tesislerinde ger\u00e7ekten \u00f6nemli olan sorunlar\u0131 \u00e7\u00f6z\u00fcyorlar: d\u00fc\u015f\u00fck kirlilik, \u00f6ng\u00f6r\u00fclebilir a\u015f\u0131nma ve \u015farj \u00f6mr\u00fc boyunca kabul edilebilir toplam maliyet.
