I have been trying to get osmium gravel (exnihilo:osmium_gravel) to go into the pulverizer and come out as 2 osmium dust (Mekanism:Dust:2 * 2) however when i use this line:
mods.thermalexpansion.Pulverizer.addRecipe(3200, exnihilo:osmium_gravel, Mekanism:Dust:2 * 2);
nothing happens. can someone explain what i have done wrong please?

forgot symbol "<" and ">"

mods.thermalexpansion.Pulverizer.addRecipe(3200, exnihilo:osmium_gravel, <Mekanism:Dust:2 * 2>);

That's Github's markdown automatically removing "bigger than" and "lower than" symbols.
