I-Limestone iyidwala le-sedimentary, ikakhulukazi elakhiwe i-calcium carbonate ne-magnesium carbonate.Inhloso yawo enkulu ukucubungula inhlanganisela yesihlabathi.Ama-chips amatshe kanye nempushana yetshe ekhiqizwa ngesikhathi sokucutshungulwa nokukhiqiza iba yinsalela ye-limestone.Izinsalela ze-limestone zigaywa zibe yimpushana ye-limestoneumshini wokugaya i-limestone.Ingasetshenziswa njengengxube kakhonkolo kanye nezingxenye ezakhiwe ngaphambili ukuze kwandiswe ukusetshenziswa kwamatshe amatshe.Njengomkhiqizi we i-limestoneumshini wokugayaumshini, HCMilling(Guilin Hongcheng) izokwethula isiceloi-limestoneumshini wokugaya umshini wokucubungula i-limestone powder.

Impushana yamaminerali e-limestone ibhekisela ezinhlayiyeni eziyimpushana ezinosayizi wezinhlayiyana ezingaphansi kuka-0.075mm (ochazwe kukhonkolo we-hydraulic enosayizi wezinhlayiyana ezingaphansi kuka-0.16mm) okhiqizwa ngesikhathi sokucutshungulwa kwenhlanganisela yesihlabathi sokwakha.Izindlela eziyinhloko zokufaka isicelo yilezi:

(1) I-limestone egaywe ibe yimpushana yezimbiwa njengengxube kakhonkolo: Ukusetshenziswa kwempushana yamaminerali e-limestone embonini kakhonkolo sekuhlolisiswe isikhathi eside.Njengengxenye eyinhloko yama-tailings, indlela yokusebenzisa i-limestone ore powder njengengxube kakhonkolo isiphenduke indawo eshisayo kanye nentuthuko embonini kakhonkolo yasekhaya.I-limestone powder iyinhlanganisela engasebenzi.Njengenhlanganisela yekhonkrithi, i-limestone powder inezinzuzo ezisobala kanye nokwenzeka: okokuqala, ukungezwa kwe-limestone powder kungasheshisa ukugeleza kukasimende;Okwesibili ukuthi izinhlayiya ze-limestone ore powder zinethonya lomumo kanye nomphumela wokugcwalisa.Akukwazi nje ukwandisa uketshezi lwengxube, ithuthukise ukuhlelwa kwezinhlayiyana zesistimu yezinto ze-cementitious, kodwa futhi ithuthukise isakhiwo se-pore sikakhonkolo;Okwesithathu, i-limestone powder inomphumela osebenzayo.Eminyakeni yamuva nje, i-China ikhiphe ngokulandelana izindinganiso zikazwelonke nezasekhaya, eziye zaqinisekisa futhi zamisa ukusetshenziswa kwempushana ye-limestone njengesisetshenziswa.Njengengxube kakhonkolo, umhlabathi we-limestone ube yimpushana yezimbiwa unemakethe ebanzi kanye nezinzuzo ezinhle zezenhlalo nezomnotho ngokuhamba kwesikhathi.

(2) Ukulungiswa kwengxube yengxenye eyenziwe ngaphambilini ngokugaya i-limestone ibe yimpushana yamaminerali: Uhlelo olusha lwezingxenye ezakhiwe lunobuhle besivinini sokwakha esisheshayo, ukulawula ikhwalithi okulula, ukonga impahla, ikhwalithi enhle yokubukeka, ukuqina okuhle, ukunciphisa ukusebenza okumanzi endaweni, kanye ukuvikelwa kwemvelo.Emkhakheni wezingxenye ezakhiwe ngaphambili, inani elikhulu le-limestone mineral powder ku-limestone tailings lingasetshenziswa njengokhonkolo kanye nezixube zikasimende.Izinga Lokulawulwa Kwekhwalithi Yezingxenye Ze-Precast Concrete (DB11/T1312-2015) lidinga ukuthi lapho kukhethwa izingxube zamaminerali ezifana ne-limestone mineral powder yokhonkolo wangaphambili, ukusebenza kwayo kufanele kuhlangabezane nezidingo zezindinganiso ezifanele.Ezinye izifundo zibonise ukuthi i-limestone powder ingathuthukisa ngokuphumelelayo i-fluidity kanye nokuphikisana nokuhlukaniswa kokhonkolo ekukhiqizeni izingxenye zekhonkrithi ezingenayo ukudlidliza kanye nokuzihlanganisa, futhi kunomphumela osobala ekubumbeni ukhonkolo, ukuxazulula izinkinga zezinto ezinganele zokusetshenziswa.Ngaphandle kwempushana ye-limestone okukhulunywe ngayo ngenhla, i-dolomite ne-granite powder enezici ezifanayo ne-limestone ingasetshenziswa futhi njengengxube kakhonkolo nosimende.

Ngaphandle kwesicelo embonini yezokwakha, izimayini ze-limestone sandstone ezisezingeni eliphezulu zingasetshenziselwa ukuthuthukisa imikhiqizo ephezulu efana ne-calcium carbonate, i-high-calcium powder ye-flux, i-limestone powder ye-desulfurization ezitshalweni zamandla ashisayo.Lezi zicelo azihlukaniseki ekusekelweni kwei-limestoneumshini wokugaya umshini.Njengomkhiqizi wei-limestoneumshini wokugayaumshini, HCMilling(Guilin Hongcheng) ukhiqiza limestone ukugaya imishini yokugaya ezifanai-limestone uRaymondumshini wokugaya, i-limestone imileumshini wokugaya, I-limestone i-ultra-fineumshini wokugayaumshini, njll. Inikeza ukusekelwa okuhle kwemishini yokukhiqiza nokusebenzisa i-limestone powder, futhi ingacubungula i-80-2500 mesh limestone powder.Iphrojekthi ye-limestone powder inokuhlangenwe nakho okucebile ekwakhiweni kanye namacala amaningi wamakhasimende.

Uma unezidingo ezifanele, sicela usithinte ukuze ufunde imininingwane yesisetshenziswa i-limestoneumshini wokugaya umshini.
