The Rock Crusher is a machine introduced in the Railcraft mod. It functions much like the macerator from IndustrialCraft. 12 Rock Crushers must be placed in a 2x3x2 grid for the machine to work. The machine will also need to be powered by Engines, using up to 15 MJ of Buildcraft power. It has 9 input slots and 9 output slots. Also, it is very loud, so build it far from your home.
- When processing gravel, the Rock Crusher has less than a 1% chance to produce gold nuggets and/or diamonds.
