Zida zowunikira feteleza wophatikiza makina
Zida zamakina zowunikira feteleza zimagwiritsidwa ntchito kulekanitsa zinthu zomalizidwa za feteleza wapawiri malinga ndi kukula kwake.Nthawi zambiri imakhala ndi makina owonera ma rotary, makina owonera ma vibration, kapena makina owonera mizere.
Makina owonera ma rotary amagwira ntchito pozungulira ng'oma sieve, yomwe imalola kuti zida ziwonekere ndikuzilekanitsa potengera kukula kwake.Makina owonera ma vibration amagwiritsa ntchito injini yogwedezeka kuti agwedeze chinsalu, chomwe chimathandiza kulekanitsa zida.Makina ojambulira mzere amagwiritsa ntchito chinsalu chozungulira chozungulira kuti alekanitse zida kutengera kukula ndi mawonekedwe ake.
Makina owunikirawa amagwiritsidwa ntchito kwambiri m'mizere yopangira feteleza kuti awonetsetse kuti zinthu zomwe zamalizidwa zikukwaniritsa kukula kwa tinthu tating'ono komanso miyezo yapamwamba.
