Ekwenziweni kwebhodi lesifunda eliphrintiwe (i-PCB), ukunemba kubalulekile. Esinye sezingxenye ezibalulekile ezithinta ukunemba umbhede wegranite osetshenziswa emishinini yokubhoboza i-PCB. Uhlelo lokumiswa kwalawa ma-lathe egranite ludlala indima ebalulekile ekuthuthukiseni ukusebenza kanye nokunemba komshini.
I-Granite yaziwa ngokuqina kwayo okuhle kakhulu, okwenza ibe yinto efanelekile yokusetshenziswa ngokunemba. Lapho imibhede ye-granite ilenga emshinini wokubhoboza we-PCB, ihlukaniswa nokudlidliza nokuphazamiseka kwangaphandle okungathinta inqubo yokubhoboza. Lolu hlelo lokumisa luvumela i-granite ukuthi igcine isicaba sayo nokunemba kwayo, okubalulekile ekuqinisekiseni ukuthi izimbobo zokubhoboza zihambisana kahle nomklamo wesekethe.
Ngaphezu kwalokho, ukumiswa kombhede wegranite kusiza ukunciphisa imiphumela yokwanda kokushisa. Njengoba amazinga okushisa eshintshashintsha ngesikhathi senqubo yokunyathela, izinto zinganda noma zinciphe, okubangela ukungahambisani kahle. Ngokumisa umbhede wegranite, abakhiqizi banganciphisa le miphumela yokushisa, baqinisekise ukuthi umbhede uhlala uzinzile futhi balondoloze ukunemba kokunyathela.
Enye inzuzo ebalulekile yombhede we-granite olengayo yikhono lawo lokumunca ukushaqeka. Ngesikhathi sokusebenza kokunyathela, umshini uvezwa emandleni ahlukahlukene angabangela ukudlidliza. Umbhede we-granite olengayo usebenza njengohlelo lokudambisa, umunca lezi zigameko futhi uzivimbele ukuthi zingadluliselwa ezingxenyeni zomshini. Lokhu akugcini nje ngokwandisa impilo yenkonzo yemishini, kodwa futhi kuthuthukisa ikhwalithi yama-PCB alengayo.
Ngamafuphi, ukumiswa kwemibhede ye-granite enembile emishinini yokubhoboza i-PCB kuyisici esibalulekile sokuklama ukuthuthukisa ukunemba, ukuzinza nokuqina. Ngokuhlukanisa i-granite ekudlidlizeni nasekushintsheni kokushisa, abakhiqizi bangafinyelela ukunemba okukhulu ekukhiqizweni kwe-PCB, ekugcineni bathuthukise ukusebenza kwamadivayisi kagesi. Njengoba isidingo sama-PCB asezingeni eliphezulu siqhubeka nokukhula, ukubaluleka kwalokhu kusungulwa kwenqubo yokukhiqiza akunakuphikiswa.
