  • Ball Mills

    The apparent difference in capacities between grinding mills (listed as being the same size) is due to the fact that there is no uniform method of designating the size of a mill, for example: a 5′ x 5′ Ball Mill has a working diameter of 5′ inside the liners and has 20 per cent more capacity than all other ball mills designated as 5′ x 5′ where the shell is 5′ inside diameter and

  • Exploring ball size distribution in coal grinding mills

    ρ charge = total coal mass + ball mass / J ∗ Mill volume. α is the angle of repose, which is estimated to be about 35°. Mill capacity increases linearly with increasing ball load for both ball sizes within the considered range. The 30 mm ball draws slightly more power as J increases from 11 to 16% but the gain in capacity is much more.

  • Coal Mill

    The analysis [45] proves that the maximum capacity of the ball-ring mill is obtained using 5 or 6 balls. Because earlier, as a rule, a greater number of balls was used, there is a possibility to increase the capacity by replacing the existing balls through a lower number of bigger balls.
