Crusher is a small mod by duke605 that adds ore doubling. Its purpose is to add a way to double ores, without adding a lot of other content, like other mods, such as Thermal Expansion and IndustrialCraft 2. It is just a simple, fuel-based ore doubler.
The Crusher is a block from the mod of the same name. This block is used to turn ore blocks into dusts. It will turn a single ore into two dusts, like a Macerator. It requires solid fuel in the bottom slot, and the ores in the top slot.
