I-limestone iyidwala eliyi-sedimentary, eliqukethe kakhulu i-calcium carbonate kanye ne-magnesium carbonate. Inhloso yalo eyinhloko ukucubungula i-sand aggregate. Ama-chips amatshe kanye ne-stone powder ekhiqizwa enkambisweni yokucubungula nokukhiqizwa iba yi-limestone tailings. Ama-lime tailings agaywa abe yi-limestone powder yi-umshini wokugaya i-limestoneIngasetshenziswa njengengxube yekhonkrithi kanye nezingxenye ezenziwe kusengaphambili zekhonkrithi ukuze kusetshenziswe kakhulu ama-chip amatshe. Njengomkhiqizi we i-limestoneumshini wokugayaumshini, i-HCMilling (Guilin Hongcheng) izokwethula ukusetshenziswa kwei-limestoneumshini wokugaya umshini wokucubungula impuphu ye-limestone.

Impuphu yamaminerali e-limestone ibhekisela ezinhlayiyeni zempuphu ezinosayizi wezinhlayiya ezingaphansi kuka-0.075mm (ezichazwe kukhonkrithi ye-hydraulic enosayizi wezinhlayiya ezingaphansi kuka-0.16mm) ezikhiqizwa ngesikhathi sokucubungula i-aggregate yesihlabathi sokwakha. Izindlela eziyinhloko zokusetshenziswa yilezi:

(1) I-Limestone egayiwe ibe yimpuphu yamaminerali njengokuhlanganiswa kwekhonkrithi: Ukusetshenziswa kwempuphu yamaminerali ye-limestone embonini yekhonkrithi sekufundwe isikhathi eside. Njengengxenye eyinhloko yemisila, indlela yokusebenzisa i-limestone ore powder njengokuhlanganiswa kwekhonkrithi isibe yindawo eshisayo kanye nomkhuba wokuthuthuka embonini yekhonkrithi yasekhaya. I-limestone powder iyinhlanganisela engasebenzi. Njengengxube yekhonkrithi, i-limestone powder inezinzuzo ezisobala kanye nokusebenziseka kwayo: okokuqala, ukungezwa kwempuphu ye-limestone kungasheshisa ukumuncwa kwekhonkrithi; Okwesibili ukuthi izinhlayiya zempuphu ye-limestone ore zinomphumela wokuma kanye nomphumela wokugcwalisa. Akugcini nje ngokwandisa ukugeleza kwengxube, kuthuthukise ukufakwa kwezinhlayiya ohlelweni lwezinto ezisimende, kodwa futhi kuthuthukise nesakhiwo sembobo yekhonkrithi; Okwesithathu, i-limestone powder inomphumela osebenzayo. Eminyakeni yamuva nje, iShayina ikhiphe ngokulandelana amazinga kazwelonke nawasendaweni, aqinisekisile futhi alinganisela ukusetshenziswa kwempuphu ye-limestone njengomthombo. Njengengxube yekhonkrithi, i-limestone egayiwe ibe yimpuphu yamaminerali inemakethe ebanzi kanye nezinzuzo ezinhle zomphakathi nezomnotho ngokuhamba kwesikhathi.

(2) Ukulungiswa kokuhlanganiswa kwezingxenye ezenziwe kusengaphambili ngokugaya i-limestone ibe yi-mineral powder: Uhlelo olusha lwezingxenye ezenziwe kusengaphambili lunezinzuzo zesivinini sokwakha esisheshayo, ukulawula ikhwalithi okulula, ukonga izinto, ikhwalithi yokubukeka okuhle, ukuqina okuhle, ukusebenza okumanzi okuncishisiwe endaweni, kanye nokuvikelwa kwemvelo. Emkhakheni wezingxenye ezenziwe kusengaphambili, inani elikhulu le-limestone mineral powder emisileni ye-limestone lingasetshenziswa futhi njenge-concrete kanye ne-cement admixtures. Izinga Lokulawula Ikhwalithi Yezingxenye Zekhonkrithi Ezilungiselelwe Ngaphambi (DB11/T1312-2015) lidinga ukuthi lapho kukhethwa i-mineral admixtures njenge-limestone mineral powder yekhonkrithi eyenziwe kusengaphambili, ukusebenza kwayo kufanele kuhlangabezane nezidingo zezindinganiso ezifanele. Ezinye izifundo zibonise ukuthi i-limestone powder ingathuthukisa ngempumelelo ukugeleza kanye nokulwa nokuhlukaniswa kwekhonkrithi ekukhiqizweni kwezingxenye zekhonkrithi ezenziwe kusengaphambili ezingenayo i-vibration kanye ne-self-compact, futhi inomthelela osobala ekubunjweni kwekhonkrithi, ixazulule izinkinga zezinto zokusetshenziswa ezinganele. Ngaphezu kwe-limestone powder okukhulunywe ngayo ngenhla, i-dolomite kanye ne-granite powder enezakhiwo ezifanayo ne-limestone nayo ingasetshenziswa njenge-concrete kanye ne-cement admixtures.

Ngaphezu kokusetshenziswa embonini yokwakha, izimayini zesihlabathi se-limestone zezinga eliphezulu zingasetshenziswa ukuthuthukisa imikhiqizo esezingeni eliphezulu njenge-calcium carbonate, i-high-calcium powder for flux, i-limestone powder for desulfurization ezitshalweni zamandla ezishisayo. Lezi zicelo azihlukaniseki nokusekelwa yi-i-limestoneumshini wokugaya umshini. Njengomkhiqizi wei-limestoneumshini wokugayaumshini, i-HCMilling (Guilin Hongcheng) ikhiqiza imishini yomshini wokugaya i-limestone efana ne-i-limestone Raymondumshini wokugaya, i-limestone eqondileumshini wokugaya, i-limestone enhle kakhuluumshini wokugayaumshini, njll. Inikeza ukwesekwa okuhle kwemishini yokukhiqizwa nokusetshenziswa kwempuphu ye-limestone, futhi ingacubungula i-powder ye-limestone enama-mesh angu-80-2500. Iphrojekthi yempuphu ye-limestone inolwazi oluningi ekuklanyweni kanye nasezimweni eziningi zamakhasimende.

Uma unezidingo ezifanele, sicela usithinte ukuze uthole imininingwane yemishini i-limestoneumshini wokugaya umshini.
