Emkhakheni wokulinganisa ukunemba, umshini wokulinganisa ubude uyidivayisi eyinhloko yokuqinisekisa ukunemba kobukhulu bemikhiqizo, futhi ukusebenza kwesisekelo sawo kuthinta ngokuqondile ukuzinza nempilo yesevisi yezinto zokusebenza. Eminyakeni yamuva nje, inani elikhulayo lemishini yokulinganisa ubude seliqalile ukusebenzisa i-granite njengento eyisisekelo. Esinye sezizathu ezibalulekile zalokhu amandla okukhathala avelele egwadle. Idatha yokuhlola ibonisa ukuthi amandla okukhathala we-granite aphakeme ngokuphindwe kasikhombisa kunalawo ensimbi ekhonjiwe. Le nzuzo ephawulekayo inikeza isiqinisekiso esiqinile sokwandisa impilo yesevisi yesisekelo somshini wokulinganisa ubude.
Ukuqinisekisa umehluko wamandla okukhathala phakathi kwegranite ne-cast iron, ithimba locwaningo lenze uchungechunge lokuhlolwa okuqinile. Ukuhlolwa kukhethwe amasampuli egwadle nezisekelo zensimbi ezisansimbi zokucaciswa okufanayo nangaphansi kwezimo zokulingisa zezimo zokusebenza ezifanayo. Ngomshini wokuhlola ukukhathala, imithwalo eshintsha ngezikhathi ezithile isetshenziswa kumasampula esisekelo sezinto ezimbili ukuze kulingise amandla angaphandle afana nokudlidliza nokucindezela umshini wokulinganisa ubude ongaphansi kwawo ngesikhathi sokusetshenziswa isikhathi eside. Ngesikhathi sokuhlolwa, izinguquko ze-microstructure, izimo zokulimala kwendawo kanye nezinga lokuwohloka kwezakhiwo zemishini ye-macroscopic yento ngemva kokuba umjikelezo wokulayisha ngamunye urekhodwe ngokunembile.
Ngemuva kwenani elikhulu lokuhlolwa kwe-loop, imiphumela iyamangalisa. Imifantu yokukhathala esobala ivele kumasampula esisekelo sensimbi ngemuva kwenani elincane lemijikelezo yokulayisha. Njengoba inani lemijikelezo landa, le mifantu ikhula ngokuqhubekayo futhi ihlangane, okuholela ekubhujisweni kobuqotho besakhiwo sezinto ezibonakalayo kanye nokwehla okukhulu kwezakhiwo zayo zemishini. Kodwa-ke, amasampula esisekelo se-granite aqala ukukhombisa imifantu emincane emincane emihle kakhulu kuphela ngemuva kokudlula emijikelezweni yokulayisha izikhathi ezimbalwa kune-cast iron, futhi isivinini sokusabalalisa ukuqhekeka sasihamba kancane kakhulu. Ngokombono we-macroscopic, izinga lokucekelwa phansi kwempahla eyimishini yezisekelo ze-granite liphansi kakhulu kunalelo lezisekelo zensimbi. Ngokuhlaziywa kochwepheshe bedatha nokubala, ekugcineni kwafinyelelwa esiphethweni sokuthi amandla okukhathala ezinto zegwadle aphakeme ngokuphindwe kasikhombisa kunalawo ensimbi ekhonjiwe.
Isizathu esenza izinto ze-granite zibe namandla amakhulu okukhathala kuhlobene eduze nesakhiwo sazo sangaphakathi kanye nezakhiwo zamaminerali. I-Granite iyidwala elivuthayo elakhiwe inhlanganisela eseduze yamakristalu amaminerali ahlukahlukene. Izinhlayiya zamaminerali ngaphakathi kwayo ziyahlangana, zakha isakhiwo esiminyene nesizinzile. Lesi sakhiwo senza i-granite ihlakaze ngokulinganayo ukucindezeleka lapho ingaphansi kwamandla angaphandle, ukunciphisa ukwenzeka kokuhlushwa kokucindezeleka kwendawo, ngaleyo ndlela kubambezeleke ngokuphumelelayo isizukulwane nokwandiswa kwemifantu yokukhathala. Ngokuphambene, kukhona ezinye izimbotshana ezincane kanye nokungcola ngaphakathi kwensimbi ekhonjiwe. Lezi zinkinga ziba "indawo yokuzalela" yokuqala ukukhathala. Uma bebhekene namandla angaphandle, bathambekele ekubangeleni ukugxila kwengcindezi futhi basheshise ukuhluleka kokukhathala kwezinto.
Ngomshini wokulinganisa ubude, amandla aphezulu okukhathala kwesisekelo se-granite kusho ukuthi ngesikhathi sokusetshenziswa kwesikhathi eside, ukuzinza nokunemba kwesakhiwo kungagcinwa kangcono. Iphutha lokulinganisa elibangelwa ukuguqulwa kokukhathala kwesisekelo liye lancishiswa, futhi ukwethembeka kwemiphumela yokulinganisa kuye kwathuthukiswa. Phakathi naleso sikhathi, njengoba isisekelo se-granite singathandeki kakhulu ekulimaleni kokukhathala, sinciphisa kakhulu imvamisa yokulungisa kanye nezindleko zokushintshwa kwemishini, futhi sandise kakhulu impilo yesevisi iyonke yomshini wokulinganisa ubude.
Ezimweni zanamuhla zokukhiqiza lapho izidingo zokunemba zemikhiqizo ziqina kakhulu, ukuzinza kokusebenza komshini wokulinganisa ubude, njengesisetshenziswa esibalulekile sokulawula ikhwalithi, kubaluleke kakhulu. Impahla ye-Granite, namandla ayo okukhathala adlula kude awensimbi ecijile, inikeza ukukhetha okungcono kokuklama nokukhiqizwa kwesisekelo somshini wokulinganisa ubude, ibe imfihlo ebalulekile yokwelula impilo yesevisi yesisekelo somshini wokulinganisa ubude nokuqinisekisa ukunemba kokulinganisa okunembile. Ibophezelekile ukudlala indima enkulu ekukhuthazeni ukuthuthukiswa kobuchwepheshe bokulinganisa ukunemba.
