## Closed circuit ball mill – Basics revisited ScienceDirect

Closed circuit milling flowsheet The total solids mass flow of the mill discharge is: (2) Q + CQ = Q ( 1 + C) The final product mass flow in the mill discharge is Q / E and the amount of final product in the circulating load is: (3) Q E Q = Q 1 E 1 The mass flow of the coarse material in the mill discharge is the difference between theIntroduction Over the years, ball mill circuits closed with cyclones have become an industry standard, and since the early days, it has been recognised that classification efficiency and circulating load both have a major effect on the efficiency of closed circuit grinding (ie its capacity to produce the desired final product)Closed circuit ball mill – Basics revisited ScienceDirectFor a closed circuit ball mill flowsheet as represented in Figure 2, a simplified relationship (Equation 1) for relative capacity at different circulating load and classification efficiencies wasClosed circuit ball mill – Basics revisited | Request PDF
