The total feed to the ballmill was therefore 11.54 T. per hr. or 179 per cent, of the original feed. It was evident that the ballmill was greatly underloaded in this test, but so much trouble developed in the classifier, due to the tendency of the sands to slip down the slopes, that a more rapid feed was not attempted at this time.
