The total feed to the ballmill was therefore 1154 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
