Lapho kukhiqizwa amapayipi ekhonkrithi aqinile acindezelwe (amapayipi e-PHC ngamafuphi), inqubo yokukhiqiza "ukwelapha kwesibili", ehlanganisa ukwelapha umusi womoya kanye nokwelapha i-autoclave, ivame ukusetshenziswa. Impuphu yesihlabathi se-silica (noma isihlabathi esihle esigayiwe) isetshenziswa ekukhiqizweni kwamapayipi e-PHC ngokusebenzisa izici zokusabela kokwenziwa kwe-hydrothermal ngesikhathi sokwelapha i-autoclave Lobu buchwepheshe abugcini nje ngokunciphisa ukusetshenziswa kwesimende, kodwa futhi bungonga amandla futhi bunciphise ukusetshenziswa. Ngesikhathi esifanayo, bungasebenzisa ngempumelelo izinsizakusebenza ze-quartz debris ezishiywe emayini, ezinezinzuzo ezinhle zobuchwepheshe nezomnotho. Ngakho-ke, yimiphi imishini esetshenziswa ukukhiqiza isihlabathi se-silica esihle esigayiwe samapayipi? Njengomhlinzeki ochwepheshe weisihlabathi se-silicaumshini wokugaya umshini, HCMilling(Guilin Hongcheng)'sIsihlabathi se-silica se-HLMumshini wokugaya oqondileiye yasetshenziswa kabanzi ekukhiqizeni isihlabathi se-silica esigayiwe kahle samapayipi, okuzochazwa ngezansi.

Ngokusho kophenyo, iSunwood isebenzise i-silica sand powder ekukhiqizeni amapayipi e-PHC isikhathi eside, kodwa ayikho indinganiso yomkhiqizo we-silica sand powder. Ukuze kuqinisekiswe ikhwalithi yamapayipi ekhonkrithi aqinile kakhulu acindezelwe, kukhuthazwe kangcono intuthuko yemboni yamapayipi, kukhuthazwe ukusetshenziswa kabanzi kwe-silica sand powder, kuqinisekiswe ikhwalithi ye-silica sand powder, futhi kulinganiswe imakethe ye-silica sand powder, ngokusho kweDokhumenti No. 7 yeKhomishini Yentuthuko Nokuguqulwa KwaseShayina ngo-2005, Izinga lomkhakha wezinto zokwakha i-JC/T 950-2005 Silica Sand Powder yamapayipi ekhonkrithi aqinile acindezelwe, abhalwe yi-Civil Engineering Research Institute yaseJiaxing University of Suzhou Concrete and Cement Products Research Institute, yakhishwa ngoFebhuwari 14, 2005 futhi yaqala ukusebenza ngoJulayi 1, 2005.

Ngakho-ke, yimiphi imishini engasetshenziswa ukukhiqiza isihlabathi se-silica esicolekile samapayipi ukuze kuhlangatshezwane nezidingo zekhwalithi yesihlabathi se-silica esicolekile samapayipi? Isihlabathi se-silica siyiminerali ye-silica eqinile, engagugi futhi eqinile ngamakhemikhali ene-SiO2: njengokwakheka kwamaminerali okuyinhloko kanye nosayizi wezinhlayiya ezingu-0.020 ~ 3.350mm. Umbala wayo umhlophe ofana nobisi, uphuzi okhanyayo, onsundu nompunga, ubulukhuni 7, ukuphuka ngaphandle kokuqhekeka, ukuqhekeka okufana negobolondo, ukukhanya kwamafutha, ubuningi obuhlobene 2.65. Ayincibiliki ku-asidi, incibilika kancane kusisombululo se-KOH, iphuzu lokuncibilika 1750C. Ngokusho kwezici zomzimba zesihlabathi se-silica kanye nezidingo zekhwalithi yemikhiqizo yesihlabathi se-silica esicolekile samapayipi. Kucatshangwa ukuthi i-roller, isihlabathi se-silicaumshini wokugaya oqondile kanye ne-ball mill yesihlabathi se-silica kungahlangabezana nezidingo zenqubo yokugaya isihlabathi se-silica. Lapho umthamo wokucubungula isihlabathi se-silica ungama-5-10t/h, i-roller njenge-silica sand mill yokugaya inamandla amakhulu, kodwa ukutshalwa kwezimali kohlelo kuphezulu. Ngemva kokuphuka kwengcindezi yesibili, usayizi womkhiqizo kunzima ukuhlangabezana nezidingo, futhi intengo iphezulu. Ukuntuleka kwedatha yokuhlola edingekayo. Kunzima ukuhlangabezana nezidingo; I-ball mill kulula ukuyigaya ngokweqile, usayizi wezinhlayiya kunzima ukuwulawula, ukusetshenziswa kwamandla kukhulu, umthamo wokukhiqiza uphansi, ukugeleza kwenqubo kuyinkimbinkimbi, futhi imishini ihlanganisa indawo enkulu. Nakuba intengo yokutshalwa kwezimali iphansi, ayifanele ukukhiqizwa okukhulu kwesihlabathi se-silica esigayiwe kahle samapayipi. Ngakho-ke,Isihlabathi se-silica se-HLMumshini wokugaya oqondile ekugcineni yakhethwa njengemishini yokukhiqiza isihlabathi se-silica esigayiwe kahle samapayipi ngemuva kokukhethwa okuphoqelekile kwamakhasimende epayipi.isihlabathi se-silicaumshini wokugaya, isihlabathi se-silicaumshini wokugaya oqondile inomthamo omkhulu, uhlelo olulula, ukusebenza okuthembekile, ukusebenza okulula, ukucophelela komkhiqizo okulawulwayo kanye nokusetshenziswa kwamandla aphansi. Isimiso sayo sokusebenza kanye nezici zokusebenza yilezi ezilandelayo:

① Isimiso sokusebenza:isihlabathi se-siliconokuqondileukugayaumshini wokugaya Injini iqhuba idiski yokugaya ukuze ijikeleze nge-reducer eqondile, bese izinto zokusetshenziswa eziqinile zingena phakathi kwediski yokugaya ngedivayisi yokondla evala umoya kusukela endaweni yokudla, bese ziphonswa emngceleni wediski yokugaya ngaphansi kwesenzo sensimu yamandla e-centrifugal bese zichotshozwa ngokugoqa okuphindaphindiwe kwe-roller yokugaya. Izinto ezichotshoziwe zigcwele kusukela emaphethelweni epuleti yokugaya, futhi izinto eziwumpuphu ezikuyo zithwalwa umoya ogeleza ngesivinini esikhulu okhuphuka engxenyeni engezansi yomshini, bese ukugeleza komoya okhuphukayo nezinto eziwumpuphu kudlula emshinini wokugaya. Engxenyeni engenhla ye-powder concentrator, ngaphansi kwesenzo se-rotor ejikelezayo ngokushesha, i-coarse powder iyahlukaniswa bese iphonswa phakathi kwepuleti yokugaya ukuze iphinde igaywe, bese i-coarse powder igaywa kusukela engxenyeni engenhla ye-silica sand grinding mill kanye nokugeleza komoya, bese iqoqwa kudivayisi yokuqoqa uthuli, okuwumkhiqizo. Izinto ezihlanganisiwe ezingathwalwa ukugeleza komoya zizogcwala ipuleti lokugaya bese zibuyela endaweni yokungena yokuphakelayo yesigayo nge-elevator yamabhakede okujikeleza kwangaphandle, bese zingena esigayweni ukuze ziphinde zigaywe kanye nezinto zokusetshenziswa ezisanda kufakwa.

② Izici zokusebenza:

1. Ihlanganisa imisebenzi yokugaya, ukomisa, ukuhlela kanye nokudlulisa. Kulula ukuyisebenzisa nokulungisa, ngezinga eliphezulu lokuzenzakalela kanye nomthamo omkhulu wokucubungula womshini owodwa.

2. Ubukhulu bemikhiqizo egayiwe bungalungiswa, futhi ukusebenza kahle kokukhetha impuphu kuphezulu.

3. Ukuguga okuphansi, ukusetshenziswa kwensimbi okuphansi, izinto ezingagugi kakhulu ze-disc lining kanye ne-roll surface, impilo yenkonzo ende.

4. Ukusebenza okuthembekile kanye nokugcinwa okulula. I-grinding roller ingakhishwa emzimbeni womshini ngesikhathi sokulungiswa.

5. Ukudlidliza okuphansi, umsindo ophansi, ukungabikho kothuli ngesikhathi sokusebenza kwengcindezi engemihle.

Inqubo yokukhiqiza isihlabathi se-silica esicolekile samapayipi isebenzisa uhlelo lokugaya isihlabathi se-silica ngokuqondile: inquboisihlabathi se-silicaumshini wokugaya Umshini uqala kusukela ekwamukeleni nasekugcineni kuya ekuthuthweni kwesihlabathi se-silica esiqediwe, okuhlanganisa ukwamukelwa nokugcinwa kwesihlabathi se-silica, ukugcinwa kwe-elevator yamabhakede, ukugaya isihlabathi se-silica ngokugaya okuqondile, ukuqoqwa kothuli lwesikhwama, kanye nokuthuthwa ngaphandle kwesihlabathi se-silica esiqediwe.

① Ukwamukela nokugcina isihlabathi se-silica: isihlabathi se-silica sithuthwa siyiswe endaweni yokwamukela i-hopper ngeloli noma siye endaweni yokugcina impahla kuqala bese siyiswa endaweni yokwamukela i-hopper nge-forklift.

② Indawo yokugcina izinto ze-lifti yamabhakede: izinto zokusetshenziswa zixhunywe ne-lifti yamabhakede ukuze kuphakanyiswe isihlabathi se-silica siye endaweni yokugcina izinto zokusetshenziswa zesihlabathi se-silica.

③ Ukugaya: ibhini lezinto zokusetshenziswa zesihlabathi se-silica lixhunywe ne-silica sand roller mill eqondile nge-flange, futhi izinto zokusetshenziswa zifakwa ku-silica sand roller mill eqondile kusukela endaweni yokungena yokuphakelayo ye-isihlabathi se-silicaokuqondileukugayaumshini wokugayayokugaya.

④ Ukuqoqwa kothuli lwezikhwama: uma ucabangela izidingo zokuvikela imvelo, idivayisi yokuqoqwa kothuli lwezikhwama isethwe ekugcineni kokukhipha umshini wokugaya.

⑤ Ukuthuthwa ngaphandle kwesihlabathi se-silica esiqediwe: isihlabathi se-silica esifanelekile ngemva kokugaywa nge-ball mill singena ebhandeni lokuthuthwa langaphandle nge-chute ekugcineni kokukhipha, bese sithuthwa siyiswe ebhinini lezinto ezisetshenziswayo egumbini lokuhlanganisa, noma sihlanganyele ngqo ekuhlanganiseni.

I-HCMilling (Guilin Hongcheng) ingumkhiqizi weisihlabathi se-silicaumshini wokugaya oqondile. Ezethu isihlabathi se-silicaumshini wokugaya oqondileiye yafakwa ekukhiqizweni kumaphrojekthi amaningana okukhiqiza isihlabathi se-silica esigaywa kahle samapayipi, futhi iqashelwa kakhulu futhi iyathandwa amakhasimende. Uma ufuna ukwazi kabanzi mayelana nokucushwa kwemishini kanye nokukhiqizwa kanye nokusebenza kwesihlabathi se-silica esigaywe kahle samapayipi, sicela uxhumane ne-HCM ukuthola imininingwane.
