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
