To illustrate how grinding conditions can affect ball mill efficiency, the batch grinding model will be used to model closed circuit ball milling of the soda lime glass. For this model, the size range of a particulate assembly in a batch mill is divided into size intervals with a maximum size X 1 above and a minimum size X n+1.
The feeder uses two same motors and two same exciters as the excitation source . Exciter is a special device with eccentric. It is vibration actuator equipment to generate centrifugal force by driving exciter rotating eccentric, which is powered by motor rotation.

SAG is an acronym for Semi Autogenous Grinding. SAG mills are autogenous mills but use grinding balls like a ball mill. A SAG mill is usually a primary or first stage grinder. SAG mills use a ball charge of 8 to 21%. The largest SAG mill is 42' (12.8m) in diameter, powered by a 28 MW (38,000 HP) motor.
