Ultrafine Ring Roller Mill

VSG mndandanda mphete wodzigudubuza mphero amagwiritsa ntchito mfundo za zotsatira, extrusion ndi akupera kuphwanya zipangizo.Kapangidwe ka magawo angapo ndi mawiri ophwanyidwa angapo zimapangitsa kuti mankhwalawa akhale ndi izi:

1> Chiŵerengero chachikulu chophwanyidwa ndi kugwiritsa ntchito mphamvu zambiri.Calcium carbonate yokhala ndi tinthu tating'ono <10 mm imasinthidwa kukhala ufa wabwino wa<10µm nthawi imodzi, ndipo ufa wabwino wa - 2.5µm umakhala pafupifupi 40%, wokhala ndi malo enieni enieni.Lili ndi ubwino wochita bwino kwambiri komanso kugwiritsa ntchito pang'ono ufa wopangidwa ndi makina othamanga kwambiri, ndipo uli ndi ubwino wa mankhwala pafupi ndi mphero ya mpweya.

2> The tinthu kukula kwa mankhwala ndi chosinthika ndi fineness ndi zabwino.Ndiwo zida zoyenera zopangira zowuma zopanda zitsulo zachitsulo.Makina akuluakulu ali ndi makina owerengera.Gudumu loyikamo lili ndi kapangidwe kake ndipo silimayendera ufa wosalala.Ubwino wa mankhwalawa ukhoza kusinthidwa malinga ndi zosowa.Ikhoza kupanga ufa wabwino ndi D97 = 5-8 µ m ndi ufa wonyezimira ndi D97 = 10-40µm.

3> Kupulumutsa mphamvu: Ndi mtundu wa zida zabwino zogaya zomwe zimagwiritsidwa ntchito kwambiri masiku ano.Malinga ndi kafukufuku wa Hefei Cement Research and Design Institute, kugwiritsa ntchito mphamvu zonse (kwh/t) kwa zida zingapo zomwe zimagwiritsidwa ntchito popanga D97<10µm heavy calcium fine powder: Raymond mill 130, impact 260, vertical mphero 175, mchenga wouma. mphero 150, vibration mphero 160, mphero 160, ndi mphete 95.
