Oomatshini be-SHANVIM bavelisa iindawo eziphezulu ze-Vertical Shaft Impactor. Sinamacandelo aphezulu kubo bonke abenzi bomatshini abakhulu, Izixhobo zokugqoka ze-VSI ziqulethwe ngaphakathi nangaphandle kwi-rotor.
Ukukhethwa kweendawo ezichanekileyo zokunxiba kwisicelo esifunekayo kubalulekile ukuqinisekisa ukusebenza okufunwayo. Amacandelo kufuneka akhethwe ngokweempawu zemathiriyeli ye-abrasiveness kunye nokukwazi ukutyumza, ubungakanani bokutya kunye nesantya seRotor ukuhambelana neemfuno zemveliso.
