  • Modelling SAG milling power and specific energy

    Two new SAG milling models are developed in this work, able to predict power or specific energy consumption, including the usual design variables such as mill size; balls charge level, solids concentration in the SAG mill feed and % of critical speed, but adding a variable that represents the feed size distribution. The −6″ +1″ (−152 +25 mm) size class was used because in many plants

  • Modelling SAG milling power and specific energy

    In these circuits the SAG mill is the largest energy consumer. In many engineering projects either a power equation and/or a specific energy equation are used for the designing of these mills but not always with acceptable results. In general these equations are used to predict power consumption as a function of mill size, level and density of

One such consideration is the decision to use a pebble crusher in the SAG mill circuit. This adds grinding capability to the SAG mill and allows the selection of a smaller

  • Difference Between Sag Mill vs Ball Mill mech4study

    In ancient time, the mills were operated with muscle power (by hands), water animals and wind. They were totally based on the mechanical energy by natural resources and living beings.There are many types of mills which are used in the grinding industries. Today we will discuss about two important mill, sag mill and ball mill. Sag Mill vs Ball Mill: Semi-Autogenous Grinding Mill SAG Mill
