A process is described for upgrading powdered coal to improve the usefulness thereof as a fuel for internal combustion engines which consists of: (a) pressure-leaching powdered coal having a particle size ranging from about 28 mesh to about 200 mesh in an aqueous caustic solution at a temperature ranging from about 175/sup 0/C, to about 350/sup 0/C., the amount of caustic in the ...

The grindability of coal is important for entrained-flow gasifiers, which require pulverized coal for dry feeding systems or coal with a wide range of particle size distribution for slurry feeding systems. Because grinding is an inefficient process, choosing coals that are easier to grind can increase the overall efficiency of the process.

Answer: Yes, but…. By "coffee grinder", I assume you mean an inexpensive grinder designed for home use in grinding coffee beans.
