Kwimizi-mveliso yezemigodi yehlabathi, ukumba, kunye nokucubungula amacandelo, ii-crushers zezona zixhobo ziphambili zemigca yemveliso, kwaye iindawo zazo zokuguguleka—kuquka iipleyiti zemihlathi, ii-cone liners, ii-blow bars, kunye nee-hammer tips—zezona zinto zibalulekileyo ezisetyenziswayo. Kubaqhubi, ukutshintshwa rhoqo kweendawo zokuguguleka akunyusi nje iindleko zokuthenga ngokuthe ngqo kodwa kukwabangela ixesha lokungasebenzi elicwangcisiweyo, elinokunciphisa ukusebenza kakuhle kwemveliso ngokubanzi nge-15-25% ngonyaka, ngokwezibalo zoshishino. Abaqhubi abaninzi bagxila kuphela kwixabiso lokuthenga kwangaphambili leendawo zokuguguleka, kodwa bangazinaki izizathu eziphambili zokusilela kwangethuba, okukhokelela kumjikelo ombi wokutshintshwa okuphindaphindiweyo kunye neendleko ezikhulayo. Eli nqaku lichaza izizathu eziphambili zokusilela kweendawo zokuguguleka kwe-crusher, kwaye labelana ngamaqhinga aqinisekisiweyo oshishino okwandisa ubomi benkonzo, ukunceda abaqhubi ukuba baphucule iindleko ezipheleleyo zobunini (TCO) kunye nokwandisa ukuqhubeka kwemveliso.
Izizathu Eziphambili Zokusilela Kweenxalenye Zokunxiba Kwangaphambi Kwexesha
Ukuqonda iindlela zokusilela linyathelo lokuqala lokwandisa ubomi beendawo ezigugileyo. Idatha yeshishini ibonisa ukuba ngaphezulu kwe-90% yokusilela kweendawo ezigugileyo ngaphambi kwexesha kuvela kwizizathu ezine eziphambili, uninzi lwazo eziqikelelwayo nezinokuthintelwa.
Isizathu esiphambili, esibangela ukuwohloka kweendawo ezingaphezulu kwama-80%, kukuwohloka okurhabaxa. Oku kwenzeka xa amasuntswana aqinileyo, abukhali eeminerali kwizinto zokutya ekrwela, esika, kwaye etshabalalisa umphezulu wenxalenye yokuwohloka ngexesha lenkqubo yokutyumza. Ubunzima bokuwohloka okurhabaxa bunxulunyaniswa ngqo nobunzima bezinto zokutya: umzekelo, amatye aphezulu e-silica afana ne-granite, i-basalt, kunye ne-iron ore abangela ukuwohloka okukhawulezayo kakhulu kunezinto ezithambileyo ezifana ne-limestone okanye amalahle. Kwanakwizinto ezinganyangekiyo kakhulu, ukuhlelwa kokutya okungahambelaniyo kunye namasuntswana amancinci kakhulu kunokukhawulezisa ukuwohloka okurhabaxa, njengoko inkunkuma encinci isebenza njengephepha lesihlabathi phakathi kwezinto ezityumzayo.
Indlela yesibini eqhelekileyo yokusilela kukusilela kokudinwa yimpembelelo. Oku kuxhaphake kakhulu kwii-jaw crushers, ii-impact crushers, kunye nee-hammer crushers, apho iindawo ezigugileyo zijongana neempembelelo ezinamandla aphindaphindwayo ezivela kwizinto zokutya. Ekuhambeni kwexesha, imithwalo yempembelelo ejikelezayo idala ii-micro-cracks kumphezulu wenxalenye; ezi qhekeko ziyanda ngokusetyenziswa okuqhubekayo, ekugqibeleni zikhokelela ekuqhekekeni, ekuqhekekeni, okanye nasekuqhekekeni ngokupheleleyo kwenxalenye. Ukungaphumeleli kwempembelelo kudla ngokuba mandundu zizinto zokutya ezinkulu, izinto zangaphandle ezingaqhekekiyo (ezifana neziqwenga zesinyithi okanye ii-drill bits) kwi-feed, kunye namazinga okutya angaguqukiyo abangela ukugqithiswa ngequbuliso.
Okwesithathu, ukuguguleka kokubola yinto edla ngokungajongwa kodwa echaphazelayo, ingakumbi kwizicelo zemigodi. Xa kusetyenzwa i-ore enomxholo ophezulu wesalfure, iiminerali ezine-asidi, okanye izinto ezigcwele umswakama, ukuguguleka kweekhemikhali kwenza buthathaka ulwakhiwo lwesinyithi lwenxalenye yokuguguleka. Ukuguguleka kudala imingxunya kunye neendawo ezinemingxuma kumphezulu, ezingagcini nje ngokunciphisa ubukhulu obusebenzayo benxalenye kodwa zikwaba ziindawo zokuqala zokuguguleka kokubola kunye nokwanda kweentanda. Kwiindawo zokutyumza ezimanzi, indibaniselwano yokuguguleka kunye nokuguguleka inokunciphisa ubomi benxalenye yokuguguleka ukuya kuthi ga kwi-40% xa kuthelekiswa neemeko zokusebenza ezomileyo.
Okokugqibela, ukufakwa okungafanelekanga kunye nokusebenza okungekho semgangathweni kubangela isabelo esikhulu sokusilela kwangethuba. Kwaneendawo zokuguguleka ezikumgangatho ophezulu ziya kusilela kwangethuba ukuba zifakwe ngendlela engafanelekanga: umzekelo, izithuba zokufakelwa ezingafanelekanga, ukuqina okunganelanga kwezibophelelo, okanye ukungalungelelani kakuhle kwezinto kunokubangela ukusasazwa koxinzelelo olungalinganiyo, ukuguguleka okugqithisileyo kwendawo, kwanokwaphuka ngequbuliso. Ukongeza, iiparameter zokusebenza ze-crusher ezingalunganga—ezifana nokuseta icala elivaliweyo kakhulu (CSS), isantya se-rotor esingahambelaniyo, okanye ukusebenza ngokugqithisileyo kwexesha elide—nazo ziya kukhawulezisa ukuguguleka kwaye zinciphise ubomi benkonzo.
Amaqhinga Aqinisekisiweyo Okwandisa Ubomi Benkonzo Yeenxalenye Zokunxiba
Ukwandisa ubomi bezinto ezigugileyo ze-crusher akupheleli nje ekukhetheni izinto ezinzima, kodwa kukudibanisa ukufanisa izinto, ukuphucula inkqubo, kunye nokugcinwa okusemgangathweni. Apha ngezantsi kukho amaqhinga asebenzayo, avavanyiweyo entsimini anika iziphumo ezilinganisekayo kubaqhubi.
Okokuqala nokubalulekileyo, khetha izinto ezifanelekileyo kwiimeko ezithile zokusebenza. Eyona mpazamo inkulu eyenziwa ngabaqhubi kukukhetha inxalenye yokuguguleka enobukhulu obufanayo, endaweni yokufanisa izinto kunye nesicelo. Umzekelo, intsimbi ye-manganese e-austenitic (efana ne-Mn13Cr2) ifanelekile kwiimeko zokutyumza ezinempembelelo ephezulu, njengoko isebenza nzima xa itshayiswa ukuze yenze umphezulu onganyangekiyo ngelixa igcina ukuqina kwangaphakathi. Kwiimeko zokuguguleka okuncinci, intsimbi emhlophe ye-chromium ephezulu inika ukumelana okuphezulu kokuguguleka. Kwiimeko zokusebenza ezinzima ezinempembelelo ephezulu kunye nokuguguleka okuphezulu, izinto ezidityanisiweyo ze-bimetallic zidibanisa ukuqina kwentsimbi ye-manganese kunye nokuxhathisa kokuguguleka kwe-alloy ephezulu ye-chromium, zibonelela ngobomi benkonzo obude obuyi-30-50% kunezixhobo ezizodwa. Ukusebenza ne-foundry yobungcali enokwenza ngokwezifiso iifomyula zezinto ngokusekelwe kwizinto zakho zokutya ezithile kunye neemeko zokusebenza kubalulekile ekwandiseni ubomi benxalenye.
Okwesibini, phucula ulawulo lokutya ukuze kuncitshiswe ukuguguleka okungeyomfuneko. Ukuqinisekisa ukuba ubungakanani bezinto zokutya bukwimigaqo eyilelwe yi-crusher kususa ukugqithiswa okukhulu kwempembelelo okubangela ukungaphumeleli kokuqhekeka. Ukufaka izixhobo zokubona isinyithi kunye nezahluli zemagnethi kumgca wokutya kususa izinto zangaphandle ezingagugulekiyo, kuthintela umonakalo omkhulu kwiindawo zokuguguleka. Ukongeza, ukugcina izinga lokutya elifanayo nelilinganayo kuthintela ukulayisha okungalinganiyo kunye nokuguguleka kwendawo, ngelixa ukuvavanya kwangaphambili ukususa amasuntswana amancinci angaphezulu kunciphisa ukuguguleka okurhabaxa phakathi kwezinto ezityumzayo.
Okwesithathu, sebenzisa ukufakelwa okusemgangathweni kunye neenkqubo zokugcinwa rhoqo. Ukulandela ngokungqongqo izikhokelo zofakelo zomenzi kuqinisekisa ukufakwa ngokufanelekileyo kunye nokusasazwa koxinzelelo olulinganayo kuyo yonke indawo egugileyo. Kwiipleyiti ze-jaw crusher, ukujikeleza rhoqo kweepleyiti ze-jaw ezizinzileyo nezishukumayo kunokulinganisa iipateni zokuguguleka, njengoko icandelo elisezantsi leepleyiti ze-jaw lidla ngokuguguleka ngokukhawuleza kunecandelo eliphezulu. Ukuhlolwa kwemihla ngemihla okubonakalayo kunye nokuhlolwa rhoqo kwe-torque yee-fasteners kunokufumana izinto ezikhululekileyo okanye iimpawu zokuqala zokuguguleka ngaphambi kokuba zikhokelele ekusileleni okukhulu, kunciphisa ixesha lokungasebenzi elingalindelekanga.
Okokugqibela, sebenzisa ubuchwepheshe obuphambili bokuphosa kunye nonyango lobushushu obuvela kubathengisi abaziwayo. Ukusebenza kweendawo zokugquma akuxhomekekanga nje kuphela kulwakhiwo lwezinto kodwa nakwinkqubo yokuvelisa. Iinkqubo zokuphosa ngokuchanekileyo, ezifana nokuphosa igwebu elilahlekileyo, ziqinisekisa uxinano lwezinto ezifanayo kunye nezinto ezingenaziphene, ngelixa unyango lobushushu oluphuculweyo (njengokuqinisa amanzi kwintsimbi ye-manganese kunye nokucima isinyithi kwi-chromium ephezulu) kwandisa ubulukhuni kunye nokuqina kwezinto. I-foundry yobungcali enolawulo oluqinileyo lomgangatho inokubonelela ngeendawo zokugquma ngokusebenza rhoqo, iphephe ukutshintsha kwe-batch-to-batch okukhokelela kubomi obungenakucingeleka.
Isiphelo
Ubomi benkonzo yeendawo zokuguguleka ze-crusher bubangelwa kukudibana kokukhethwa kwezinto, iimeko zokusebenza, kunye neendlela zokulungisa. Ngokuqonda izizathu eziphambili zokusilela kunye nokusebenzisa amaqhinga achazwe apha ngasentla, abaqhubi banokwandisa kakhulu ubomi beendawo zokuguguleka, banciphise ixesha lokungasebenzi, kwaye banciphise iindleko zemveliso iyonke.
