Therefore the SAG mill speed could not be controlled using the microphone based signal and instead was manually controlled/set by the control room operator. Thus operation/speed of the mill could and would change significantly based on a particular operator running the mill and their overall level of mill operation experience and skill.
critical speed of ball mill. ball mill critical speed mineral processing metallurgyjun 20 2015 183; a ball mill critical speed actually ball rod ag or sag is the speed at which the centrifugal forces equal gravitational forces at the mill shells inside surface and no balls will fall from its position onto the shell the imagery below helps explain what goes on inside a mill as speed varies .

Buildup in critical size: It is well established from the earliest use of AG and SAG mills that the buildup of competent critical size material, can drop throughput to half (Morrell and Valery
It is an approximation or a best guess based on limited data. This equation is: y = 225 x (1) Where x = the load in the mill expressed as measured % by volume and y = kg/h of feed. This information is based on observed throughput reductions caused by loading the 3ft. SAG mill to over 26% by volume.
