Indima Yezihlungi Ezidlidlizayo Ekulawulweni Kwekhwalithi Ekukhiqizweni Kukasimende

Ekukhiqizweni kwe-cement, ikhwalithi engaguquki yomkhiqizo iyisidingo esingenakuxoxiswana ngaso. Phakathi kwamathuluzi amaningi okulawula inqubo yokukhiqiza, ama-vibrating screens adlala indima evame ukubukelwa phansi kodwa ebaluleke kakhulu ekuqinisekiseni ukuthi izinto zokusetshenziswa, imikhiqizo ephakathi nenqubo, kanye ne-cement yokugcina kuhlangabezana nezidingo eziqinile zosayizi wezinhlayiya. I-vibrating screen eklanywe kahle ayithuthukisi ukusebenza kahle kokukhiqiza kuphela, kodwa iphinde ibe nomthelela oqondile ekufaneni komkhiqizo wokugcina, inciphise ubungozi bamaphutha ezigabeni ezilandelayo zokukhiqiza. Kubaphathi bezitshalo zokukhiqiza kanye nonjiniyela bekhwalithi abahlola izixazululo zokuhlunga, ukuqonda ukuthi le mishini inegalelo kanjani ekulawuleni ikhwalithi kuyisinyathelo sokuqala sokwenza isinqumo sokutshala imali esinolwazi. Lesi sihloko sihlola imisebenzi ebalulekile yama-vibrating screens ekukhiqizweni kwe-cement, sichaze imingcele esemqoka ethinta ukusebenza kokuhlunga, futhi sethule izinzuzo zama-vibrating screens e-Haiside ekutholeni imiphumela yekhwalithi engaguquki.

Indima Eyisisekelo Yama-Vibrating Screens Ekukhiqizweni Kwe-Cement

Ama-vibrating screens yimishini esebenza ngomshini ehlukanisa izinto eziningi ngokususelwa kusayizi wezinhlayiya ngokusebenzisa ukuhlukaniswa kwezingqimba kanye nokudlula kwezinto okubangelwa ukudlidliza. Ekukhiqizweni kwe-cement, asetshenziswa ezigabeni eziningi, kusukela ekuchotshozweni kwezinto zokusetshenziswa (i-limestone, i-clay ne-gypsum) kuya ekupholiseni i-clinker nasekuqedeni umkhiqizo wokugcina. Iminikelo yawo eyinhloko ekulawuleni ikhwalithi ihlanganisa:

Ukuphakelwa Okungaguquki Kwezinto Zokusetshenziswa – Ngokuqinisekisa ukuthi izinto zokusetshenziswa ezingena emshinini wokugaya zingaphakathi kobubanzi obuthile bosayizi, ama-vibrating screens avimbela izinhlayiya ezinkulu kakhulu ukuthi zingalimazi imishini yokugaya futhi agcine ukusatshalaliswa kosayizi wezinhlayiya okufanayo ukuze kuthuthukiswe ukusabela kwamakhemikhali.
Ukuhlukaniswa Komkhiqizo Ophakathi Nenqubo – Ngemva kokushisisa ngaphambi kwesikhathi kanye ne-calcination, i-clinker kufanele ipholiswe futhi ihluzwe ukuze kususwe izingxenye ezincane kakhulu noma ezinkulu kakhulu ezingathinta ukusebenza kahle kokugaya. Lesi sinyathelo sinomthelela oqondile ku-Blaine fineness kanye namandla okucindezela e-cement yokugcina.
Ukufana Komkhiqizo Wokugcina – Esigabeni somshini wokugaya wokuqeda, ama-vibrating screens ahlukanisa i-cement egayiwe ukuze kutholakale usayizi wezinhlayiya odingekayo (ngokuvamile <45 µm ku-Portland cement). Ukuhlunga okunembile kuqinisekisa ukuthi i-cement ifinyelela indawo ethile edingekayo futhi kugwema ukwenqatshwa komkhiqizo ngenxa yokungahlangabezani nezidingo zekhwalithi.

Ngayinye yalezi zinhlelo idinga i-screen ekwazi ukuphatha umthamo omkhulu wokusebenza, imelane ne-blinding (ukuvaleka kwezimbobo), futhi inikeze izindawo zokuhlukanisa ezinembile ngaphansi kwezimo ezinothuli nezibangela ukuguguleka. Ngaphandle kokuhlunga okusebenzayo, ukushintshashintsha kosayizi wezinhlayiya kungaholela ezikhathini ezingaguquki zokuqina kwe-cement, ekunciphiseni kwamandla, kanye nokwanda kwezikhalazo zamakhasimende.

Indlela Idizayini Ye-Vibrating Screen Ethinta Ngayo Ukusebenza Kokulawulwa Kwekhwalithi

Akuwona wonke ama-vibrating screens asebenza ngokulinganayo ekulawuleni ikhwalithi ye-cement. Imingcele eminingi yokuklama nokusebenza inquma ukuthi i-screen ingakwazi yini ukugcina ukunemba kokuhlukanisa okudingekayo ngokuhamba kwesikhathi:

Indlela Yokudlidliza Nokulawulwa Kwe-Amplitude

Iphethini yokudlidliza (i-linear, circular noma elliptical) kanye ne-amplitude kuthinta ngokuqondile ukuhamba kwezinto nokwakheka kwezingqimba. Ezinhlelweni ze-cement, ama-linear motion screens avame ukukhethwa ngoba ahlinzeka ngokusheshisa okufanayo kuyo yonke i-deck, okunciphisa ubungozi bokuhlukana kwezinhlayiya. I-amplitude elungisekayo ivumela opharetha ukuthi balungise i-screen ngokunembile ukuze isebenze ngezinto ezahlukene ngaphandle kokushintsha i-eccentric mass. Ama-vibrating screens e-Haiside afaka uhlelo oluqinile lwe-eccentric shaft drive olunikeza amandla okudlidliza angaguquki ngisho nalapho imithwalo yokuphakelwa ishintsha, okuqinisekisa ama-cut points azinzile.

Ukukhethwa Kwe-Screen Media

Uhlobo lwe-screen deck – i-woven wire mesh, ama-polyurethane panels noma amashidi erabha – luthinta kokubili ukuqina nokusebenza kahle kokuhlunga. Ezitshalweni ze-cement, ukuguguleka nokugqwala okubangelwa umswakama nezinhlayiya ezincane kusheshisa ukonakala kwe-screen media. I-high-tensile steel wire noma ama-polyurethane modular panels anikeza impilo ende yokusebenza kanye nokumelana ne-blinding. I-Haiside inikeza izinhlobo ezahlukene ze-screen media ezimelana nokuguguleka futhi eziklanyelwe ngokukhethekile izindawo zokukhiqiza i-cement, ezinezindawo ezivulekile ezilungiselelwe ukukhulisa umthamo wokucubungula ngaphandle kokunciphisa ukunemba.

Izici Zokuvimbela I-Blinding

I-blinding – lapho izinhlayiya zibambeka ezikhaleni noma zinamathele ebusweni be-screen – iyimbangela enkulu yokuphambuka kwekhwalithi. Ama-vibrating screens asetshenziswa ku-cement kufanele abe nezici ezifana nama-ball decks, ultrasonic vibrations noma i-trapezoidal wire ukuze kugcinwe izikhala zivulekile. I-Haiside ihlanganisa uhlelo oluthuthukile lokuzihlanza olusebenzisa i-adjustable ball tray support ukuze lwehlise i-blinding kuze kufike ku-40% uma kuqhathaniswa nemiklamo evamile, lugcine ukusebenza kahle kokuhlunga kungaguquki ngisho nasezintweni ezinomswakama ophezulu.

Izinto Ezibalulekile Ekukhetheni I-Vibrating Screen Yokulawula Ikhwalithi Ye-Cement

Lapho kuhlolwa abahlinzeki bama-vibrating screens ukuze kusetshenziswe ekulawuleni ikhwalithi ye-cement, abathatha izinqumo kufanele baqhathanise izici zokusebenza ezithinta ngokuqondile ukufana komkhiqizo. Uhlu olulandelayo lufingqa izindlela ezibalulekile zokukhetha kanye nendlela ama-screen e-Haiside abhekana ngayo nazo:

Ukuqhathaniswa Kwezixazululo Zokuhlunga Zekhwalithi Ye-Cement

Ukunemba kwe-Cut-point: Ama-screen ajwayelekile angaphambuka ngo-±2–3% uma kuqhathaniswa ne-nominal aperture; ama-screen e-Haiside afinyelela ukunemba kwe-±1% ngokusebenzisa ama-deck akhiqizwe ngokunemba kanye nesakhiwo sefreyimu esiqinile.
Umthamo wokucubungula: Ama-screen amaningi alahlekelwa ukusebenza kahle kokuhlukanisa lapho imithwalo iphezulu. I-angle yokudlidliza elungiselelwe kanye ne-adjustable stroke angle kuma-screen e-Haiside kuvumela umthamo ofinyelela ku-200 t/h ku-deck eyodwa ngaphandle kokulahlekelwa ukunemba kwe-cut.
Ukuqina ezimweni ezinokuguguleka: I-Haiside isebenzisa amapuleti aseceleni ensimbi eqinisiwe kanye nama-wear liners ashintshwayo ezindaweni zokuthintana, okwandisa izikhathi phakathi kokulungiswa ngo-30–50% uma kuqhathaniswa nesilinganiso semboni.
Ukunakekelwa okulula: Ama-deck panels akhishwa ngokushesha kanye nezindawo zokugcoba ezihlanganiswe endaweni eyodwa kunciphisa isikhathi sokuma. Ama-screen e-Haiside aklanyelwe ukushintshwa ngokushesha kwe-screen media – ngokuvamile ngaphansi kwemizuzu engu-30 nge-deck ngayinye.
Ukuhlanganiswa kwe-automation & control: I-Haiside inikeza ama-vibration frequency converters ongawakhetha kanye nokuqapha i-amplitude ngesikhathi sangempela, okuvumela ukulungiswa okuzenzakalelayo ukuze kugcinwe ukuhlukanisa okungaguquki naphezu kokushintsha kokuphakelwa.

Abaphathi bekhwalithi ye-cement kufanele futhi bacabangele ulwazi lomhlinzeki embonini. I-Haiside isineminyaka engaphezu kwengu-15 ihlinzeka izitshalo ze-cement ngama-vibrating screens, inerekhodi lokusiza amakhasimende ukuthi afinyelele izidingo zekhwalithi eziqinile futhi anciphise amazinga okwenqatshwa kwemikhiqizo.

Isiphetho

Ama-vibrating screens awuwona nje imishini eyisizayo, kodwa ayizingxenye ezibalulekile zokulawulwa kwekhwalithi ekukhiqizweni kwe-cement. Kusukela ekuqinisekiseni ukuphakelwa okungaguquki kwezinto zokusetshenziswa kuya ekutholeni i-fineness enembile ye-cement yokugcina, ukusebenza kwawo kuthinta ngokuqondile ukufana komkhiqizo, ukusebenza kahle kwesitshalo kanye nokwaneliseka kwamakhasimende. Ngokukhetha i-screen enokulawula okuqinile kokudlidliza, izici zokuvimbela i-blinding kanye nesakhiwo esiqinile, njengalezo ezinikezwa yi-Haiside, abakhiqizi be-cement banganciphisa ukushintshashintsha kwekhwalithi futhi bagcine ukuhambisana nezindinganiso zamazwe ngamazwe. Ezinhlanganweni ezifuna ukuthuthukisa inqubo yazo yokulawula ikhwalithi, ukuhlola ngokucophelela ubuchwepheshe bokuhlunga kuwukutshalwa kwemali okuletha izinzuzo ngokunciphisa imikhiqizo enqatshwayo kanye nokwandisa ukwethembeka kokusebenza.
