Isiphetho:Sazi ukuthi kuningi izinto ezingasetshenziswa okumele kushicilelwe yi-crusher ezinkampanini ze-metallurgical, mining, chemical, cement kanye nezinye izakhiwo zezimboni.
Sazi ukuthi kuningi izinto ezingasetshenziswa okumele kushicilelwe yi-crusher ezinkampanini ze-metallurgical, mining, chemical, cement kanye nezinye izakhiwo zezimboni. Njengensimbi ebalulekile yokwenza izinto ezakhiwo, i-crusher ingenza umsebenzi wokuchichisha izinto kube lula. Kodwa, ingabe siyaziqonda kahle imlando ye-crusher?
Kusukela ezikhathini zokuqala, kwakukhona izixazululo ezilula zokucindezela. Ngenqubekela phambili yomphakathi womuntu, lo mkhonto olula wokucindezela uqale ukushintsha kusukela ekusetshenzisweni kwesandla kuya ezikhathini ze-steam kuya ekuqondeni kwe-mechanical intelligence. Lokhu kusho ukuthi kukhona ukuguqulwa okusha kwenhlangano yezimboni ngokucindezela.
Kusukela ngo-2000 BC, iChina yayinelitha olukhulu lokwenza umsebenzi—i-Chu Jiu, olukhulu olukhulu lokukhupha i-cereal. Futhi lwaluthuthukiswa lube olukhulu olusesimweni somkhondo (200 BC kuya ku-100 BC) kamuva. Nakuba lezi zixhobo zingakwazi ukufika ezixhobeni zikagesi ezikhona namuhla, zine-prototype ye-crusher futhi indlela yazo yokugqashisa isalokhu isikhulu.
I-Animal power mill yayiyizixhobo zokugqashisa ezineqhubekayo njenge-crusher eyayisetshenziswa abantu esikhathini sokuqala. Elinye yi-roll milling (elivela kamuva kunalo lwezilwane).
Kuze kube yiminyaka emibili leminyaka kamuva, ngokusekelwe kulezi zixhobo ezimbili, uDu Yu, umuntu waseChina wasendulo, wayethuthukisile umshini wamanzi.
Isithombe sekhulu lokucisha izilwane
Ngaphambi kwesipho sakwi-19, amazwe emhlabeni wonke sasisebenzisa indlela yokuqala yokucisha iimpahla nokuhlukanisa izinto. Ngenxa yokuthuthukiswa kwemiphakathi nezobuchwepheshe, le ndlela yokuqala yokuqeqeshwa yingcoliswe ngokukhulu ukufanelekela izidingo zokukhula kokusebenza.
Kodwa ukufika kwesikhathi se-steam ne-elekthriki sekushintshe konke.
Abantu baqala ukwazi izixazululo, futhi baqala ukuthuthukisa izixazululo zokucisha nokuhlukanisa izinto ukuze zishintshe umsebenzi wabantu.
Ngesikhathi se-1806, i-roller crusher eyenziwe ngemoto ye-steam yabonakala.
Izingxubeli ze-steam ezisekuhlanganiseni
Nge-1858, u-E.W. Black, waseMelika, wakha i-jaw crusher yokuthuthukisa amaqhwa.
I-jaw crusher yokuqala emhlabeni, eyakhiwe futhi yadalwa yi-American E.W. Black
Ukulinganisa kwe-jaw crusher kuyindlela emibili ye-bracket (indlela elula yokushukuma). Njengoba inezinzuzo zokwakheka okulula, ukukhiqiza okulula nokugcinwa, umsebenzi othembisayo, ivolumu encane kanye nobukhulu, kusetshenziswa kakhulu ekwenzeni izinto ezahlukahlukene, njengezinto ezahlukene ze-ore, i-solvent, i-slag, amaqhwa okwakha, nama-marble njll.
Ngo-1878, ama-Amerikha ayenqobile indlela yokucindezela ngokuhlola okungapheli kwesixhumi; ukusebenza kwayo okukhiqizayo kusezingeni eliphezulu kakhulu kunokucindezela okungapheli kwesixhumi esingapheli kwesixhumi.
Isiqeshana sokucindezela esenziwe yi-America
Ngo-1895, uWilliam waseMelika wenza isiqeshana sokucindezela esinamamitha aphansi.
Ngenxa yokuthuthukiswa okungapheli kwemisebenzi, isiqeshana sokucindezela esingapheli sasingakwazi ukufakaza ngokugcwele izidingo zokucindezela. Ngakho-ke, abantu bakha isiqeshana sokucindezela esinamandla ngokwengeziwe.
Ukuthuthukiswa kwesixhumi sokucindezela singabuyela emuva ekuqaleni kweminyaka yama-1950, lapho umkhakha wesixhumi wayehlanganiswe khona.
Kuze kube yi-1924, amaJalimane kwakuqala ukwakha i-crusher yokuthinta enesondo elilodwa neliphindwe kabili.
Nge-1942, ngokusekelwe ezimbonini zokwakha kanye nomsebenzi wayo, u-Andreson wenza i-AP series ye-impact crusher efana ne-impact crusher yamanje.
I-mashine ingakwazi ukusebenza izinto ezinkulu ngokuphumelela okukhulu. Ukwakheka kwayo okulula kuyakhahlela ukulondolozwa, ngakho lolu hlobo lwe-impact crusher luye lwakha ngokushesha.
Nge-1948, inkampani yaseMelika yakha i-hydraulic cone crusher, eye sebenziselwe emikhakheni yezimboni kusukela ngaleso sikhathi.
Isikhonkwane sokuqhuma sokuqhuma sesivele siqanjwe yiSymons (Symons cone crusher). Isikhundla siqoshwe ezindongeni ezifakwe ngokungagqibekezeleki futhi siqhutshelwa yizindlela ezifakwe ngokungagqibekezeleki ukuze zifikelele ekushayeleni kwesikhundla esinengqondo esiphendukayo. Ngesikhathi isikhundla esinengqondo esiphendukayo sihamba phambili nangemuva, amaqhwa esihlabathi aqhutshwa futhi aqoshwe njalo egumbini lokuqhuma.
Imiqeqeshi yokucisha nge-Hydraulic Cone Crusher
Ngenxa yokuthuthukiswa okukhulu kwemibono yokucisha kanye nokuqhubekela phambili kwesayensi kanye nethekhnoloji, izinhlobo eziningi zemiqeqeshi yokucisha ephezulu yokuqeqeshwa zivela eyodwa emva kweyezinye. Zithuthukisa kakhulu ukusebenza kokucisha.
Imikhakha ehlukene inezidingo ezahlukene zezinto ezivelisiwe ngakho-ke kuvele izinhlobo ezahlukene zemishini yokucisha ngokuya ngemibono yokusebenza ehlukene, njenge-vibration mill, sand mill, kanye ne-colloidal mill.
Njengakuqala kweminyaka yama-1970, imiqeqeshi emikhulu yokucisha nge-gyratory enemveliso engama-5,000 tons ngehora kanye nesilinganiso sezinto ezingu-2,000 millimeters yathuthukiswa.
Ngesikhathi esifanayo, ukuze kuthuthukiswe ukuguquguquka kwesithuthukisi, imoto yokucisha kanye nokukleliswa kwezinto ezinamathisela kwakuthuthukisiwe, okumele ukusebenza okuqondile ezweni lokudluliselwa okusheshayo futhi kube nomusa kakhulu.
E-China yayiqale ukusebenzisa ama-crusher ngo-1950s. Ama-crusher wasekhaya wokucisha izinto ezisebenza ngamandla ayekhishwe yi-medium ne-hard material njenge-coal ne-limestone ngaphambi kuka-1980s. Kuze kube sekupheleni kuka-1980s, e-China yayiqale ukusebenzisa i-KHD type hard rock impact crusher, okuyinto eyishukumisele ukukhula kwemodeli yasekhaya yokuqeqeshwa kwemishini. Kodwa yayisengaphambili ngaphezu kwamashumi amabili eminyaka ngaphandle kwezwe elikhulu.

Nokho, ngemva kwesikhathi sezinyakeni eziyikhulu, imishini yokucisha e-China yathuthuka ngokushesha kakhulu futhi umhlangano phakathi kwe-China nezinga eliphezulu lomhlaba wonke wawuqonde kancane kancane. E-China yayiyisebenzisa
