Considering the size and complexity of large SAG mill trommel frames the latest Finite Element Analysis techniques are used to reduce fatigue stresses and ensure structural integrity The stresses considered are those induced by deformation of the support trunnion the live load as well as the mass of

SGS's comminution experts use the SAG Mill Comminution (SMC) test to characterize ore samples an important first step to grinding circuit design optimization and production forecasting Read more The SMC test is an abbreviated less expensive version of the JK Drop-weight test

What s the difference of Ball mill SAG mill AG mill Attrition mill is a type of grinding mill by kinds of media to crush lump to powder like substances The impact can be rock on rock such as in an Autogenous Grinding AG mill rock and a small ball charge 10 used in Semi Autogenous Grinding SAG mills balls of various sizes in Ball Mills and less commonly these days steel rods in Rod Mills

It is imperative to ensure the efficient removal of both slurry and coarse pebbles (critical size) in order to ensure the efficient operation of AG/SAG mills Elimination of the above mentioned material transport problems will allow the mill to respond truly in terms of power draw for changes in mill load which depends on feed ore characteristics
