= Pulverizer is a machine added by Thermal Expansion mod and its used to extract twice as much dust from ore. Pulverized ore can be cooked in any of the furnaces to produce ingots. It needs power to run, so an engine or filled redstone cells are required. It has a small chance of secondary byproduct and a slight advantage over the macerator, but it doesn't support all the ores.
