Isichotho se-SPX sand sand kanye ne-gravel trap cyclone isetshenziselwa ukususa itshe le-hydraulic DE-itshe ngemuva kokufika efektri yesitashi sommbila. Umsebenzi oyinhloko ukususa ukungcola okunjengamatshe nezinsimbi kuxutshwe kummbila ngaphambi kokuphuka, ukuvikela ngempumelelo imishini esezansi. (efana ne-crusher, njll.) ukugwema ukulimala, ngoba ihlukaniswe indlela yesiphepho se-hydro, inezici zokusebenza kokuhlukanisa okuphezulu, amandla amakhulu okusebenza, kanye nensiza encane yonyawo.
