    Flow of materials in rod mills as compared to ball mills

    The rod mill product is characterized by its narrow size distribution if it is compared with that of a ball mill operating under the same conditions in open circuit. This is partly due to the bridging action of the rods over the coarse particles avoiding the fine sizes (the grinding kinetics aspect), and partly due to the nature of material

    Nov 01, 2006 Ball mills are used for grinding of rocks, cement clinker and limestone from 10 to 100. mm feed sizes down to sub-millimetre product.. They are typically rotating cylinders with diameters from 3 to 6 m and lengths from 6 to 12 m.The flow of particulate solids within these mills can be modelled using the discrete element method (DEM)

    Feb 13, 2017 This fact should be carefully kept in mind when determining the capacity of a Steel- Head Ball-Rod Mill, as this unit can carry a greater ball or rod charge and has potentially higher capacity in a given size when the full ball or rod charge is carried. A mill shorter in length may be used if the grinding problem indicates a definite power input

    Feb 20, 2017 Due to the hindering effect that the ball charge gives to the material flow in dry grinding, the ball charge is not more than 28-35% of the mill volume. This should be compared with 40-45% in wet grinding. The expression used for this phenomenon is that the charge in a dry grinding mill is swollen

    Mar 21, 2007 Similar to slurry flow-back, the pebbles flowing back into the mill increase with larger pebble port or grate slot size. As the pebbles flow down and slide across the grate slots, they get an equal chance to go back into the mill. Similar to slurry pool formation, pebbles flow-back would increase the quantity of critical size material in the mill
