I-100mm iibhola zokusila luhlobo lwemithombo yeendaba yokusila esetyenziswa kwimisebenzi yemigodi, ngakumbi kwiindawo zokusila i-ore.Ezi bhola zenziwe ngentsimbi kwaye zinkulu ngobukhulu kunezinye iintlobo zemidiya yokusila, njenge-20mm, 25mm, 30mm, 40mm, 50mm, 60mm, 80mm, 90mm, kunye neebhola zokusila eziyi-125mm.Ubungakanani obukhulu bezi bhola bubenza bakwazi ukusebenzisa impembelelo enkulu kunye nemikhosi yokutyumza, ebalulekileyo ekusileni nasekucokiseni intsimbi ekrwada.Ebudeni benkqubo yokusila intsimbi, ezi bhola zentsimbi zidlala indima ebalulekileyo ekwaphuleni iintsimbi zibe ngamasuntswana acolekileyo.
Ukusetyenziswa okuphambili kweebhola zokugaya i-100mm kwimigodi kukwii-ore grinding mills, apho zisebenza njengemithombo ebalulekileyo yokugaya.Ezi bhola zisetyenziselwa ukusila kunye nokucokisa iintsimbi ezikrwada, okubangela ukuba kubekho amasuntswana acolekileyo anokuthi aqhubeke nokucutshungulwa ukukhupha iiminerali ezixabisekileyo.Ubungakanani obukhulu bezi bhola bubenza bakwazi ukusebenzisa impembelelo enkulu kunye nemikhosi yokutyumza, ebalulekileyo ekusileni nasekucokiseni intsimbi ekrwada.
Isishwankathelo, iibhola zokugaya i-100mm ziyinxalenye ebalulekileyo yezixhobo zokugaya i-ore ekusebenzeni kwemigodi.Ubungakanani bazo obukhulu bubenza bakwazi ukusebenzisa amandla amakhulu kunye nokutyumza amandla, okubalulekileyo ekusileni nasekucokiseni intsimbi ekrwada ekrwada.Ezi bhola zentsimbi zidlala indima ebalulekileyo ekwaphuleni intsimbi ekrwada ibe ngamasuntswana acoliweyo ngexesha lokusila, nto leyo ekhokelela ekutsalweni kweeminerali ezixabisekileyo.
