Imishini ekhethekile yokupholisa umanyolo
Imishini ekhethekile yokupholisa umanyolo isetshenziselwa ukwehlisa izinga lokushisa likamanyolo we-granulated noma oyimpuphu ngemva kokuba omisiwe.Ukupholisa kubalulekile ekukhiqizweni kukamanyolo ngoba ama-fertilizer ashisayo anganqwabelana futhi kube nzima ukuphatha, futhi angalahlekelwa izakhi zawo ngenxa yokusabela kwamakhemikhali.
Ezinye izinhlobo ezijwayelekile zemishini yokupholisa umanyolo zihlanganisa:
1.Ama-coolers ajikelezayo: Lawa ma-cooler ahlanganisa isigubhu esijikelezayo esiwisa izinto zikamanyolo kuyilapho umoya opholile uvunguza kuwo.Zifanele ukupholisa uhla olubanzi lwezinto zomanyolo, kufaka phakathi ama-granules nama-powders.
2.Ama-Fluidized bed coolers: Lawa ma-cooler asebenzisa umoya opholile ukuze akhiphe umanyolo, awumise emoyeni futhi awuvumele uphole ngokushesha.Zifanele ukupholisa izimpushana ezinhle nama-granules.
3.Ama-cooler-flow aphikisayo: Lezi zipholile zisebenzisa isistimu yomoya ogeleza ophikisanayo kanye nezinto zikamanyolo ukuze kukhuliswe ukudluliswa kokushisa nokusebenza kahle kokupholisa.Zifanele ukupholisa ama-granules amakhulu noma imikhiqizo ekhishwe.
Ukukhethwa kwezinto zokupholisa umanyolo kuncike ezidingweni ezithile zomkhiqizi kamanyolo, uhlobo nenani lezinto ezipholiswayo, kanye nesikhathi sokupholisa esifiselekayo nezinga lokushisa.Ukukhetha kahle kanye nokusetshenziswa kwezinto zokupholisa umanyolo kungathuthukisa ikhwalithi kanye nezici zokuphatha umanyolo, okuholela ekuvuneni kwezitshalo okungcono kanye nempilo yomhlabathi engcono.
