Grinder is a multiblock Structure added by the Magneticraft mod. The Grinder is the second of the machines used for ore processing that can multiply output.
It is powered by Magneticraft Low Voltage that either has to be produced by Magneticraft machines or converted from other sources of power (RF, etc) using Magneticraft converters.
The Grinder turns Chunks from the Crusher into their respective Magneticraft specific Rubble and has a small chance of also producing alternative Dusts. The Rubble can be smelted (some Rubble like the Uranium Rubble can not be smelted and must be further processed) to produce 2 Ingots or can be further refined by grinding them again in the Grinder to produce Pebbles for the Sifter. Each additional step has a small chance of producing additional Dust.
Grinder Control is a block added by the Magneticraft mod. It is the heart of the multiblock Grinder structure. The Grinder is built by placing this block one block above the ground and then right-clicking it to see a ghost layout of the other blocks to place.
