Course Details
AG/SAG Mills can accept feed up to 350mm and are used as primary grinding units. The mill is thus fed with the product from a Primary Jaw or Gyratory crusher. Grinding action is by particle-on-particle impact (AG Mills) and a combination of ball & particle-on-particle impact (SAG Mills). SAG applications include both wet and dry operation.
The discharge of the AG/SAG mill is fitted with a grate discharge, where ground material passes through slotted apertures into a pulp chamber that then lifts the material out the belly of the mill. The lifted material is then deflected into the trunnion and exits via a trommel into the mill discharge sump.
