Grindability of Various Ores The experimental grinder was a small iron tube-mill, 8 by 12½ in., in which was placed a definite number (74) and weight (3450 gm.) of ¾-in. steel balls, 1 lb. water and 1 lb. ore. To obtain uniform conditions, each ore was first crushed and screened, and from the sized products a ‘‘standard feed” was artificially prepared, the same standard being adopted for all tests in that particular series.
