Ama-crusher ayinsika yezimboni zezimayini, zokwakha, zokukhiqiza kanye nezokuvuselela imfucuza yokwakha, anesibopho sokunciphisa izinto zokusetshenziswa ezinkulu ezifana namatshe, i-ore kanye nemfucuza yekhonkrithi zibe ngosayizi ongasetshenziswa kumaphrojekthi engqalasizinda, ukwakhiwa kwezakhiwo kanye nezicelo zezimboni. Njengoba kunezinhlobo eziningi zama-crusher ezitholakala emakethe, ngayinye yenzelwe imisebenzi ethile kanye nezici zezinto ezibonakalayo, ukuqonda izimiso zazo zokusebenza, izimo zokusetshenziswa kanye nezindlela zokukhetha kubalulekile kochwepheshe bemboni ukuze bathuthukise ukusebenza kahle, banciphise izindleko futhi baqinisekise impumelelo yephrojekthi. Lesi sihloko sinikeza umbono oningiliziwe wezinhlobo zama-crusher ezivame kakhulu, izindlela zazo zokusebenza eziyinhloko kanye neziqondiso ezisebenzayo zokukhetha isayensi, ngokusekelwe emikhubeni yemboni kanye nokuqonda okusemthethweni kwezobuchwepheshe.
Zonke izigubhu zingahlukaniswa ngamaqembu amabili amakhulu ngokusekelwe ezimisweni zazo eziyinhloko zokuchoboza: izigubhu zokucindezela kanye nezigubhu zokushaya. Izigubhu zokucindezela ziphula izinto ngokuzicindezela phakathi kwezindawo ezimbili eziqinile kuze kube yilapho ziphuka, kuyilapho izigubhu zokushaya zisebenzisa izigubhu zesivinini esikhulu ukuphula izinto zibe yizinhlayiya ezincane. Isigaba ngasinye sihlanganisa izinhlobo eziningana ezijwayelekile ze-crusher, ngasinye sinemiklamo yesakhiwo ehlukile kanye nezici zokusebenza ezilungiselelwe izimo zokusebenza ezahlukene.
Ama-jaw crushers yiwona ama-crusher asetshenziswa kakhulu futhi amele ama-compression crushers. Isakhiwo sawo siqukethe ipuleti lomhlathi eliqinile kanye nepuleti lomhlathi elihambayo; ipuleti lomhlathi elihambayo lihamba liye emuva naphambili ngokumelene neliqinile ngaphansi kokuqhutshwa kwe-shaft eccentric kanye nepuleti lokugudluza, okwenza amandla okucindezela agudluza izinto ezinkulu ezifakwa ekamelweni. Ama-jaw crushers ahlukaniswe ngezinhlobo zokuguqula okukodwa kanye nokuguqula kabili, kanti amamodeli okuguqula okukodwa asetshenziswa kakhulu ezisetshenzisweni zesimanje ngenxa yamandla awo aphezulu uma kuqhathaniswa nama-double-toggle afanayo anobukhulu obufanayo. Ahamba phambili ekuphatheni izinto ezinkulu, eziqinile njenge-granite kanye ne-basalt, okwenza zibe zilungele izigaba zokugudluza zokuqala ezimayini nasema-quarry. Isakhiwo sawo esilula, ukulungiswa okulula kanye nekhono lokwamukela osayizi abakhulu bokuphakelayo (kufika kumamitha angu-1.5) kuwenze abe yimishini ebalulekile embonini yokugudluza.
Ama-gyratory crusher angolunye uhlobo lwe-compression crusher, asetshenziswa kakhulu ekuchobozeni okuyinhloko emisebenzini yokumba emikhulu. Ngokufana nokusebenza kwe-jaw crushers, ane-concave yangaphandle eqondile (egobile) kanye ne-conveyor yangaphakathi ejikelezayo (i-mantle) efakwe ku-swing shaft. Izinto zichotshozwa njalo phakathi kwama-cones amabili njengoba i-mantle gyrates, futhi uhlelo lokulungisa ukukhishwa kwe-hydraulic luvumela ukulawulwa kwesikhathi sangempela kokuhlelwa komkhiqizo wokugcina. Uma kuqhathaniswa nama-jaw crushers, ama-gyratory crushers anamandla aphezulu (afinyelela ku-1200 t/h nangaphezulu) ngenxa yendlela yawo yokuchoboza eqhubekayo kanye nokuvulwa okukhulu kokukhishwa okujikelezayo, okwenza afaneleke ezimayini ezinomthamo ophezulu lapho inani elikhulu lezinto zokusetshenziswa kudingeka licutshungulwe kahle. Kodwa-ke, isakhiwo sawo esiyinkimbinkimbi kanye nezindleko zokutshalwa kwezimali eziphakeme kunciphisa ukusetshenziswa kwawo kumaphrojekthi amancane naphakathi.
Ama-cone crushers, nawo ayingxenye yama-compression crushers, asetshenziswa kakhulu ezigabeni zokuchoboza zesibili, ezintathu kanye nezinhle kakhulu. Ngokufana nama-gyratory crushers, ahluka ngobukhulu kanye nezimo zokusetshenziswa—ama-cone crushers aminyene kakhulu futhi aklanyelwe ukuchoboza okuncane. Inqubo yokuchoboza incike ekujikelezweni okungavamile kwe-mantle, okudala amandla okucindezela phakathi kwe-mantle kanye ne-concave, kuqhekezwe izinto zibe yizinhlayiya ezifanayo. Inzuzo ebalulekile yama-cone crushers umphumela wokuchoboza phakathi kwezinhlayiya, lapho izinhlayiya zichobozana phakathi nenqubo, kunciphisa ukuguguleka kwamapuleti e-liner futhi kuthuthukiswe ikhwalithi yomkhiqizo. Afaneleka kakhulu ekucubunguleni izinto eziqinile nezinolaka, futhi uhlelo lwawo lokulungisa ukukhishwa kwe-hydraulic luvumela ukulungiswa okuqhubekayo ngaphansi komthwalo, okwenza kube ngcono ukuguquguquka kokusebenza. Ukuze kwandiswe ukusebenza kahle, ama-cone crushers anconywa ukuthi asebenze ngokuphakelwa kwegumbi eligcwele, okungatholakala ngokusebenzisa ama-silos namadivayisi okuqapha izinga.
Ama-impact crushers, asekelwe kusimiso sokuchoboza ngomthelela, ayakwazi ukusetshenziswa ngezindlela eziningi futhi angasetshenziswa ezigabeni zokuchoboza eziyinhloko, zesibili noma zesithathu. Ahlukaniswe ngezinhlobo ezimbili eziyinhloko: ama-horizontal shaft impact crushers (HSIC) kanye nama-vertical shaft impact crushers (VSIC). Ama-horizontal shaft impact crushers ane-rotor ejikelezayo esheshayo ene-blow bars; izinto zishaywa yi-blow bars bese ziphonswa emapuletini omthelela ekamelweni lokuchoboza, bese zichotshozwa ngokushayisana phakathi kwezinhlayiya, zikhiqize imikhiqizo efana ne-cubical ene-gradation enhle. Afanele ukucubungula izinto eziqinile eziphakathi nendawo njenge-limestone kanye ne-construction waste. Ama-vertical shaft impact crushers, avame ukubizwa ngokuthi "amaphampu amatshe", asheshisa izinto nge-rotor ejikelezayo futhi azikhiphe ngesivinini esikhulu, aziphule ngokushaya ngodonga lwegumbi kanye nokushayisana phakathi kwezinhlayiya. Asetshenziswa kakhulu esigabeni sokugcina sokuchoboza, ikakhulukazi lapho kudingeka ama-cubic aggregates ekhwalithi ephezulu kumaphrojekthi okwakha.
Ukukhetha i-crusher efanele kudinga ukucatshangelwa okubanzi kwezinto eziningi, okuhlanganisa izici zezinto, izidingo zokukhiqiza, izindleko zokusebenza kanye nokuhambisana nemvelo. Okokuqala, izakhiwo zezinto ezifana nokuqina, umswakama kanye nosayizi wezinhlayiya zokuqala zibalulekile: izinto zokuqina okuphezulu (isb. i-granite) zifanelekela ama-jaw crushers noma ama-cone crushers, kuyilapho izinto zokuqina eziphakathi nendawo zingacutshungulwa ngama-impact crushers. Izinto ezinomswakama ophezulu zivame ukuvaleka, zidinga ama-crusher anemiklamo ekhethekile njengezikrini ze-grate. Okwesibili, amandla okukhiqiza kanye nezidingo zekhwalithi yomkhiqizo zinquma uhlobo lwe-crusher kanye nokucushwa: amaphrojekthi amakhulu anezidingo zomthamo ophezulu angadinga inhlanganisela yama-jaw crushers nama-cone crushers, kuyilapho amaphrojekthi amancane noma ahambayo angamukela iziteshi zokuchoboza ezihambayo. Okokugcina, ukusebenza kahle kwezindleko kufanele kuhlolwe, okuhlanganisa ukutshalwa kwezimali kokuqala, ukusetshenziswa kwamandla, izindleko zokulungisa kanye nemijikelezo yokushintsha izingxenye zokuguguleka.
Ekuphetheni, ukuqonda izinhlobo ezahlukene zama-crusher, izimiso zazo zokusebenza kanye nezimo zokusetshenziswa kubalulekile ekwenzeni izinqumo zokukhetha ezinolwazi embonini yokuchoboza. Kungakhathaliseki ukuthi i-jaw crusher eqinile yokuchoboza okuyinhloko, i-gyratory crusher enamandla aphezulu ezimayini ezinkulu, i-cone crusher esebenza kahle yokuchoboza okuncane, noma i-impact crusher eguquguqukayo yemikhiqizo ye-cubic, uhlobo ngalunye ludlala indima ehlukile ekwenzeni ngcono inqubo yokuchoboza. Ngokulandela iziqondiso zesayensi zokukhetha kanye nokuhlanganisa ulwazi lwethiyori kanye nokusebenza endaweni, ochwepheshe bemboni bangakhetha i-crusher efaneleke kakhulu, bathuthukise ukusebenza kahle, banciphise izindleko futhi bakhuthaze intuthuko esimeme yezimboni zezimayini nezokwakha.
