The Crusher is a 3×5×3 multiblock added by Immersive Engineering. It is used for crushing ores into grit, which is more efficient than normal smelting.

  • Once the blocks are assembled, use the Engineer's Hammer on the center of the front of the longer side (which should be a Steel Fence with a Hopper above it) to complete the structure.


    The Crusher does not have a GUI. The machine accepts any form of Forge Energy (FE) or Redstone Flux (RF) through the top of the multiblock, through the interface shown below.

    When an entity falls into the center pit, the machine adds it to its internal inventory (composed of 2048 stacks[1]) and crushes it. Products drop out the front-bottom-center hatch, marked with an orange dot. If there is an inventory there (like a Chest), outputs land in that inventory.

    When a mob falls into the Crusher's hopper, it gets crushed, and the machine outputs its drops. If an ore falls in, it's crushed into two grits. If an ingot or gem falls in, it's crushed into a single grit. If an item that cannot be processed falls in, it stays loose in the machine's hopper. (In older versions of the mod, the item gets destroyed.No citation needed; please confirm.[citation needed])

    The speed that the Crusher processes one item is very close to the speed that a furnace processes one item when fueled with an External Heater. 2 furnaces can keep up with a Crusher that's processing ores.

    The Crusher accepts a Redstone signal through the "control panel", the front-rightmost-center block, to halt its processes.
