Mashiinnada rullaluistemadka taxanaha ah ee VSG waxay isticmaashaa mabda'a saamaynta, extrusion iyo shiidi si loo burburiyo alaabta.Qaab dhismeedka lakabyo badan iyo lammaane jajabin badan ayaa ka dhigaya alaabtan inay leedahay sifooyinka soo socda:
1> Saami burburin weyn iyo heerka isticmaalka tamarta sare.Kaalshiyam carbonate oo leh xajmi-qaybeed<10mm waxa lagu farsameeyaa budo ganaax ah<10µm hal mar, iyo budada ganaaxa ee - 2.5µm waxay u dhigantaa qiyaastii 40%, oo leh meel sare oo gaar ah.Waxay leedahay faa'iidooyinka waxtarka sare leh iyo isticmaalka hooseeya ee budada ee ay soo saarto burburinta saamaynta xawaaraha sare leh, waxayna leedahay ganaaxa alaabta ee u dhow midka hawada.
2> Cabbirka walxaha alaabada waa la hagaajin karaa, ganaaxuna waa wanaagsan yahay.Waa qalabka ugu habboon ee wax soo saarka qalalan ee ganaaxyada macdanta aan birta ahayn.Mashiinka ugu muhiimsan wuxuu ku qalabaysan yahay habka darajooyinka.Shaagaga qiimayntu waxa uu leeyahay qaab-dhismeed gaar ah mana wado budo aan dhab ahayn.Wanaagsanaanta badeecada waxaa lagu hagaajin karaa iyadoo loo eegayo baahiyaha.Waxay soo saari kartaa budo fiican oo leh D97=5-8 µm iyo budo aan dhab ahayn oo leh D97=10-40µm.
3> Badbaadinta tamarta: Waa nooc ka mid ah qalabka wax lagu shiido oo leh tamarta ugu yar wakhtigan.Marka loo eego xogta Hefei Cement Research and Design Institute, isticmaalka tamarta dhamaystiran (kwh/t) ee dhowr qalab oo inta badan loo isticmaalo soo saarista D97<10µm culus kalsiyum budada ganaax: Raymond mill 130, saamaynta mill 260, mill toosan 175, ciid qalalan Mill 150, Gariir Mille 160, Mill ball 160, iyo Roller Mill 95.
