Grinding Lignite Used

Ultra fine grinding of low-rank coal. Progress report ...

The lignite used for Phase I of the project will be a Texas lignite from the Martin Lake mine. A test plan has been submitted to the GFPO outlining the specific grinding tests to be run in the fluid-energy mill. The primary grinding fluid will be steam, but ambient air will also be used in one run to provide an expanded data base.

Material-depednent non-linear modeling of fine coal

1984-3-1  Fine grinding of lignite in a ball mill was shown to be non-linear in rate because of the presence of both weaker and stronger organic phases. Weaker phases were ground rapidly, whereas stronger phases were ground more slowly. Lignite grinding was modeled by evaluating two sets of time-independent linear breakage rate constants, one for the ...
