Sieve Bend imagwiritsidwa ntchito makamaka mu fakitale yokonzekera malasha ndi concentrator kuti isamaume madzi, ichotsedwe, ichotsedwe pakati komanso ibwezeretsedwe bwino zinthu zomwe zili ndi matope.

Chophimba chopindika ndi chimango cha chinsalu chimakhala ndi kapangidwe kapadera, komwe kamatha kuzungulira madigiri 180 kuti chiwonjezere moyo wa ntchito ya chophimbacho. Chopingasacho chimagubuduzidwa ndi bokosi lodyetsa, bokosi la chinsalu ndi shaft ya mpando wa makina ophimba, zomwe zimapangitsa kuti gawo la chakudya ndi gawo lotulutsa zigwire ntchito mofanana, kukulitsa nthawi yogwiritsira ntchito, komanso kugwira ntchito mosavuta.

Mfundo yogwirira ntchito ya chinsalu chogwedeza arc Mfundo yochotsera madzi ya chinsalu chogwedeza arc ndikulekanitsa madzi a matope ndi njira yodulira m'mbali zakuthwa zomwe zili mbali yodyera ya chinsalucho; Kutengera nthawi yogwiritsira ntchito komanso kusiyana kwa chinyezi cha zinthuzo.

Sieve Bend imagawidwa m'magulu awiri: chinsalu chogwedezeka cha arc ndi chinsalu chosakhala champhamvu cha arc. Chinsalu chooneka ngati arc chimagubuduzidwa ndi bokosi lodyetsera, bokosi lowonetsera ndi shaft ya mpando wa makina owonetsera, zomwe zimapangitsa kuti mapeto a chakudya ndi mapeto otulutsa agwirizane, zomwe zimapangitsa kuti ntchitoyo iwonongeke mofanana, kutalikitsa nthawi yogwira ntchito, komanso kugwira ntchito mosavuta. Chagwiritsidwanso ntchito kwambiri mu metallurgy, makampani opanga mankhwala ndi mafakitale ena.

Ndikusintha kosalekeza kwa mapangidwe a chinsalu chogwedezeka cha arc, mabizinesi ambiri adapanga chinsalu chotchinga chokhala ndi chiwongolero cha pivot, chomwe chimatha kuzungulira 180 °, kukulitsa moyo wautumiki wa pazenera. Kuphatikiza apo, akatswiri apanganso mawonekedwe a arc anjira ziwiri, omwe amapangidwa ndi injini yonjenjemera, wogawa ndi bokosi lowonekera. Amadziwika kuti chophimba bokosi wapangidwa ndi mbale mbali ziwiri, nthambi mipope zitsulo, zowonetsera awiri anaika n'zosiyana ndi mbale kulekana.
