Ball Mill Pulverizing
When Kincaid lignite was pulverized utilizing in-the-mill drying at product moisture content in the range of 11 to 12 percent, the comparison factor was 4.4 for pulverization in the ball mill and 4.5 in the hammermill. Power requirements at these conditions were 17.9 kwhr/ton in the ball mill and about 17 kwhr/ton in the hammermill.
