Mota huru inotyaira pulley yebhandi kuti itumire simba kudhiramu kuburikidza nebhandi retriangle, izvo zvinoita kuti dhiramu ritenderere kutenderedza axis yaro nekumhanya kukuru uye rigadzire simba recentrifugal. Pakumhanya kwekudyisa, zvinhu zvinopinda mudhiramu kuburikidza nepombi yekudyisa uye zvinogoverwa zvakaenzana pamadziro edhiramu. Kana dhiramu rasvika pahuwandu, mudzori wemazinga anoita basa rekumisa dhiramu. Kusvika pakupatsanurwa kwekumhanya kukuru. Pasi pekushanda kwesimba recentrifugal, zvinhu zvakasimba zviri muzvinhu zvinofamba zvichienda kumadziro edhiramu uye pakupedzisira zvinogara pasi. Kana chikamu chemvura chajekeswa kuti chisvike pazvinodiwa, kumhanya kwedhiramu kunoderera kusvika pakumhanya kweskimmer uye mvura yakacheneswa inobviswa mumuchina kuburikidza nepaipi yekubuda kwemvura. Chinhu chakasimba chinobatwa mukati medhiramu uye chinoita keke rekusefa. Pakupedzisira, dhiramu rinodonha kusvika pakumhanya kwekuburitsa (30-100r/min), chikwepa chinotanga kukwesha, keke rekusefa rinokweshwa pasi, chikamu chakasimba chinoburitswa kuburikidza nechiteshi chekuburitsa pasi pecentrifuge, chikwepa chinosimuka kudzokera panzvimbo yekutanga, uye maitiro ekutenderera apera.
