Closed Circuit Grinding VS Open Circuit Grinding
From a theoretical point of view, the ideal method of grinding would consist of a series of ball mills, each in closed circuit with a classifier and each so short that the ore in its passage through the mill would be struck only two or three times by the balls, any undersize produced being removed at once by the classifier ; in this way the chance of a particle being struck again after it had reached the required size …
Closed circuit ball mill – Basics revisited - ScienceDirect
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 (i.e. its capacity to produce the desired final product).

Because the ball mill closed circuit is the last stage before separation. Cyclone overflow should be clean of coarse particles. About the big pump, it’s one of the most important equipment when you are going to increase your capacity. It’s always a limitation unless you …
Grinding Circuit - an overview | ScienceDirect Topics
closed circuit ball mill. The Australian experience of milling lateritic ore is to use a high-aspect ratio mill at the initial stages of operation using a single-stage circuit. With time, as the hardness of the ore increases with depth in the mine, a second-stage ball mill is added.
Ball Mill - saVRee
Ball mills operate in a closed or open circuit. Closed circuits return a certain amount of the ball mills output back to the ball mill for further size reduction. Closed circuits are not unusual, and its also not unusual that the ore will pass two or three times through the ball mill …

Double helical feeders used in closed-circuit with classifiers; Spout feeders preferred when using a closed-circuit with classifying cyclones. Cyclones are typically installed above the mill and thus the cyclone underflow is fed to the mill by gravity. Discharge System. One exit unit; Exit about 5 – 110 cm lower than the center line of the overflow mill.
