    Milling Machine: What is a Autogenous Mill? Quora. A SAG mill uses the same properties as an AG mill but with the addition of steel balls can handle more homogenous ore hardness and achieve the desired grind size faster, allowing more throughput, and hence a lower ore feed grade in the circumstance that grinding is your processing constraint.

    AG Autogenous Grinding - Mineral Processing Metallurgy

    Autogenous Grinding Explained. Mill length was the primary variable investigated in an autogenous pilot mill circuit. The 5-½’ diameter mill had both pebble ports and ½” wide slotted grates. The plus ½” mill product was crushed in a cone crusher and returned to the mill feed along with the minus ½” plus 4 or 6 mesh fraction.

    Ore characterisation forand simulation ofprimary

    In comparison to conventional tumbling mills, i.e., rod- and ball mills, the grinding media in an autogenous mill derive from the feed ore itself (Rowland and Kjos, 1978). Any change in feed ore properties will therefore affect the grinding charge and thus, the breakage mechanisms within the mill.
