The rock crusher, a 3x2x2 structure

The Crusher is built out of 12 special blocks made from a Block of Steel, Pistons, and Diamonds. If broken down, it takes 3 Blocks of Steel, 12 Pistons, and 12 Diamonds to build one Rock Crusher. They cannot be built adjacent to each other, there must be at least one tile in between Rock Crushers (the 3x2x2 structure).

The Crusher can be loaded and unloaded via Loaders or Buildcraft pipes. The entire 3x2x2 structure is treated as a single block, similar to a large chest. It will accept input from the top and will output from any remaining side.

It will draw 15 MJ of power while processing materials. This can be easily supplied through an MFE connected to an Energy Link, or a single Steam Engine.

The crusher can also crush ores into dust just like a Macerator .

The list of materials that can be processed includes just about any vanilla blocks made from stone or brick. Additionally, you can process Bones and Blaze Rods, but one of the most important products it can produce is Obsidian Dust. Obsidian Dust has a 25% chance of being produced when processing Obsidian in addition to producing Crushed Obsidian. Crushed Obsidian can be further processed directly into Obsidian Dust if you desire, but it also makes an excellent ballast material.
