Emkhakheni wokulinganisa ngokunemba, umshini wokulinganisa ubude uyithuluzi elibalulekile lokuqinisekisa ukunemba kobukhulu bemikhiqizo, futhi ukusebenza kwezinto zawo eziyisisekelo kuthinta ngqo ukuzinza nokuphila kwenkonzo yemishini. Eminyakeni yamuva nje, inani elikhulayo lemishini yokulinganisa ubude seliqalile ukusebenzisa i-granite njengezinto eziyisisekelo. Esinye sezizathu ezibalulekile zalokhu amandla okukhathala avelele e-granite. Idatha yokuhlola ikhombisa ukuthi amandla okukhathala ezinto ze-granite aphezulu ngokuphindwe kasikhombisa kunensimbi ephonswe. Le nzuzo ebalulekile inikeza isiqinisekiso esinamandla sokwandisa impilo yenkonzo yesisekelo somshini wokulinganisa ubude.
Ukuze kuqinisekiswe umehluko emandleni okukhathala phakathi kwe-granite ne-cast iron, ithimba locwaningo lenze uchungechunge lwezivivinyo eziqinile. Ukuhlolwa kwakhetha amasampula ezisekelo ze-granite neze-cast iron ezinezincazelo ezifanayo nangaphansi kwezimo zokulingisa zezimo zokusebenza ezifanayo. Ngomshini wokuhlola ukukhathala, kufakwa imithwalo eshintsha njalo kumasampula esisekelo sezinto ezimbili ukuze kulingiswe amandla angaphandle njengokudlidliza nokucindezela umshini wokulinganisa ubude obhekana nawo ngesikhathi sokusetshenziswa kwesikhathi eside. Ngesikhathi sokuhlolwa, isakhiwo esincane siyashintsha, izimo zomonakalo womphezulu kanye nezinga lokuwohloka kwezakhiwo zemishini ezinkulu zezinto ngemuva komjikelezo ngamunye wokulayisha kwaqoshwa ngokunembile.
Ngemva kwenani elikhulu lokuhlolwa kwe-loop yokulayisha, imiphumela iyamangalisa. Ukuqhekeka kokukhathala okusobala kwavela kumasampula esisekelo sensimbi ephonswe ngemuva kwenani elincane kakhulu lemijikelezo yokulayisha. Njengoba inani lemijikelezo landa, la maqhekeka akhula njalo futhi ahlangana, okuholela ekubhujisweni kobuqotho besakhiwo sezinto kanye nokwehla okukhulu kwezakhiwo zayo zemishini. Kodwa-ke, amasampula esisekelo se-granite aqala ukubonisa imiqhekeko emincane kakhulu emincane kakhulu ngemuva kokudlula imijikelezo yokulayisha izikhathi eziningana kuneyensimbi ephonswe, futhi ijubane lokusabalala kwemiqhekeko lalihamba kancane kakhulu. Ngokombono we-macroscopic, izinga lokuwohloka kwesakhiwo semishini yezisekelo ze-granite liphansi kakhulu kunelezisekelo zensimbi ephonswe. Ngokuhlaziya idatha yobungcweti kanye nokubala, ekugcineni kwaphethwa ngokuthi amandla okukhathala ezinto ze-granite aphezulu ngokuphindwe kasikhombisa kunezensimbi ephonswe.
Isizathu sokuthi izinto zegranite zinamandla aphezulu okukhathala sihlobene kakhulu nesakhiwo sazo sangaphakathi kanye nezakhiwo zazo zamaminerali. Igranite iyidwala eliyi-igneous elakhiwe yinhlanganisela eseduze yamakristalu ahlukahlukene amaminerali. Izinhlayiya zamaminerali ezingaphakathi kwayo ziyahlangana, zakha isakhiwo esiqinile nesizinzile. Lesi sakhiwo senza igranite ikwazi ukusabalalisa ukucindezeleka ngokulinganayo lapho ibhekene namandla angaphandle, kunciphisa isimo sokugxila kokucindezeleka kwendawo, ngaleyo ndlela ibambezele ngempumelelo ukukhiqizwa nokwanda kwemifantu yokukhathala. Ngokuphambene nalokho, kunezimbobo ezincane kanye nokungcola ngaphakathi kwensimbi ephonswe phansi. Lezi ziphambeko ziba "indawo yokuzalela" yokuqalisa imifantu yokukhathala. Uma ibhekene namandla angaphandle, ivame ukubangela ukugxila kokucindezeleka futhi isheshise ukwehluleka kokukhathala kwezinto.
Kumshini wokulinganisa ubude, amandla aphezulu okukhathala kwesisekelo se-granite asho ukuthi ngesikhathi sokusetshenziswa isikhathi eside, ukuzinza nokunemba kwesakhiwo kungagcinwa kangcono. Iphutha lokulinganisa elibangelwa ukuguquguquka kokukhathala kwesisekelo linciphile, futhi ukuthembeka kwemiphumela yokulinganisa kuthuthukisiwe. Okwamanje, njengoba isisekelo se-granite singathinteki kakhulu ekulimaleni kokukhathala, kunciphisa kakhulu imvamisa yokulungisa kanye nezindleko zokufaka esikhundleni semishini, futhi kwandisa kakhulu impilo yesevisi iyonke yomshini wokulinganisa ubude.
Esimweni sanamuhla sokukhiqiza lapho izidingo zokunemba zemikhiqizo ziqina khona, ukuzinza kokusebenza komshini wokulinganisa ubude, njengemishini eyinhloko yokulawula ikhwalithi, kubaluleke kakhulu. Izinto ze-granite, ezinamandla okukhathala adlula kakhulu ensimbi ephonswe, zinikeza ukukhetha okungcono kokuklama nokukhiqizwa kwesisekelo somshini wokulinganisa ubude, okuba yimfihlo ebalulekile yokwandisa impilo yesevisi yesisekelo somshini wokulinganisa ubude nokuqinisekisa ukunemba kokulinganisa okunembile. Kuzoba nendima enkulu ekukhuthazeni ukuthuthukiswa kobuchwepheshe bokulinganisa okunembile.
