Embonini yemishini yokupakisha, kunezinhlelo eziningi zokusetshenziswa kwamaseli omthwalo, iningi lawo okuwukuhlolwa komthamo nezikali zokukala nezikali zokudlulisa nokuhlunga. Ukusetshenziswa okuyinhloko kwalezi zinzwa ukutholwa okusemgqeni kokungahambisani kwesisindo, izingxenye ezingekho noma imiyalelo phakathi nokupakishwa. Bahlinzeka ngempendulo kumishini yokupakisha ukuze baqinisekise ukuthi imikhiqizo ihlangabezana nezicaciso nezimfuneko, ithuthukisa ukusetshenziswa kwezinto ezibonakalayo, futhi ithuthukise ikhwalithi yomkhiqizo iyonke. Umkhiqizo ngokwawo wenziwe ngesidlulisi esikalayo, isilawuli kanye nesidlulisi sempahla esiphuma ngaphandle. I-conveyor enesisindo ibophezelekile ekuqoqeni isignali yesisindo futhi iyithumele kusilawuli ukuze sicutshungulwe, kuyilapho umthumeli we-infeed enesibopho sokwandisa isivinini somkhiqizo nokudala isikhala esanele phakathi kwezinto. Ngokulandelayo, isidluliseli esikhiphayo sidlala indima ebalulekile ekuthutheni imikhiqizo yokuhlola isuka endaweni yesisindo futhi isuse noma yiziphi izinto ezingalungile. Uma ufuna uhlobo olungcono kakhulu lwenzwa, cabangela amaseli omthwalo wephoyinti elilodwa, amaseli okulayisha ama-bellows noma amaseli omthwalo wohlobo lwe-S.
