AG/SAG mills are normally used to grind run-off-mine ore or primary crusher product Wet grinding in an AG/SAG mill is accomplished in a slurry of 50 to 80 percent solids 2D and 3D simulations of particles in a SAG Mill red=fastest blue=slowest moving particles [image: (135-6-4)]Get price

Mining Milling

A gyratory crusher reduces the ore to minus 15-20 centimetres The ore is then fed to a coarse ore stockpile from which it is reclaimed for grinding first to a semi-autogenous ("SAG") mill and then to a ball mill which together reduce the grain size to 80% passing 140 microns Get price
