2/20/2005· Because of physical limitations the air swept mill discharge could not be sampled. The inside mill samples were taken in the grinding chamber from nine points equally spaced along the mill axis. At each point, the material on the surface was removed and the ball and material samples were collected at a 25 cm depth.
