    Closed-circuit systems. The efficiency of the early stages of grinding in a ball mill is much greater than that for formation of ultra-fine particles so ball mills operate most efficiently by making a coarse product the fine fractions of this then being separated and the coarse part being returned to the mill inlet.

  • NEUROCONTROL OF A BALL MILL GRINDING CIRCUIT USING

    The increase in the hydrocyclone feed rate initiated by the first control loop consequently causes the second control loop in pairing I to decrease the fresh feed to the mill (reducing the mill production rate). This is primarily a response to the mill s inability to cope with the larger amount of coarse particles in the mill.
