Know MoreIn a mining plant or processing mill they have a big grinding circuit for crushing raw material these are usually Ball or SAG mills Inside these Sag/Ball mill are big steel balls that grind ore via an impact process In simple terms these hard metal steel balls get to the top of the rotating chamber and fall down crushing the ore being...

Know MoreTypically a SAG mill based circuit P80 of 106 to 150 um has media costs of around A 1/t Providing the ore is amenable the use of primary autogenous milling can reduce this cost by 40 Autogenous milling is typically practiced in association with...

Know MoreJul 29 2019 0183 32 I ve created 2 processing patterns one to have the Sag Mill turn for example Iron Ore into Iron Dust and then one for the Alloy Smelter to turn Iron Dust into Iron Ingots What I would like to do though is have this be an automated process where if I put an Iron Ore into my network the Sag Mill immediately turns it into dust and the...
